When it comes to vile predators interfering with the natural growth of your peaceful plants, these insects and other beasties do their dirty work in two main ways.

The first is chewing insects. These guys will leave holes in your plant’s leaves or eat away whole sections of them, weakening the leaf tremendously. Insects or other deviants in this category include earwigs, beetles, grasshoppers, slugs, caterpillars and snails. The second variety is the sucking variety, and yes, these guys just plain suck. These guys are generally smaller and include mites, flies and aphids, and they prey on the plant by sucking all the juices and nutrients out of the leaves, which naturally doesn’t leave your leaves in very good shape.

Don’t get the idea that all chewing creatures are big and all sucking ones are small though, and plan your attack strategy around that, because it may not be the case. There are some larger sucking creatures as well, including squash bugs, chinch bugs and stinkbugs. These guys can be as big as your little fingernail. By the same token not all chewers are big. One little bugger with a big appetite for leafy goodness is the black flea beetle, who enters the ring at just 1/4 of an inch in diameter.

You may come across leaves that become rolled, puckered or twisted out of shape after a time. The likely cause of a rolled leaf is a little green hairless caterpillar, who you’ll likely find nestled contentedly inside the leaf when you unroll it.

It could also be aphids taking up residence inside a rolled up leaf. Aphids come in a variety of colors, but are easily identifiable by their nearly transparent bodies, large abdomens with prong shaped protrusions jutting out the back, and their six legs. For these distinct little guys, a good chemical spray may be needed without causing more damage on abused leaves of even small plants like pony tail palm. This procedure can be difficult to get off manually especially on a plant with many leaves.

One last guy who leaves a distinctive trail of destruction in its wake is the leaf miner. These guys are aptly named, as they take up residence inside the leaf and tunnel around in it like a jolly miner in the mountain. The tunnels they make leave a transparent trail in the leaf that actually gives the appearance of a window in which you can look right through the leaf. You may even see the miner itself in one of these tunnels upon close inspection.

The Top Ten Enemies for Your Rose Bushes

Monday, August 18th, 2008
by Thomas Fryd

Insects might be responsible for some of the problems you are experiencing with your roses. These insects can be your roses’ worst friends, and will cause major damage if you do nothing to keep them away. These are some of the top ten most wanted enemies of your roses, and some ways to identify them and get rid of them.

1. Aphids

Aphids are the most frequent insect problem you will find in your roses. These insects like to make themselves comfortable in the roses’ growing tissues like buds and shoots. Aphids usually are just a problem during the spring and early summer.

Although few - or even moderate - numbers of aphids won’t cause much damage to your roses, you need to watch them and make sure their numbers don’t spread. A large group of aphids can produce honeydew, a waste product that has the consistency of a sugary liquid. This honeydew can encourage mold; the mold eventually will blacken the roses’ leaves. Flowers may decrease and new buds may be killed if there are large numbers of aphids in your roses.

You may not need to use insecticides to control your aphids. They have some natural enemies, including syrphid flies and lady beetles. If these insects aren’t around to deter your aphids, you can try washing them off of the roses with water or special types of soaps.

2. Spider Mites

Spider mites may be to blame if you notice that your roses’ leaves are drying up and falling off, or if they look like they have numerous small dots (stippling). These pests are so small that you might need a magnifying glass to find them.

Spider mites usually infest your roses because of dry and dusty conditions. It’s possible to try to control them by reducing the amount of dust and by making sure that your roses and other plants have enough water.

3. Fuller Rose Beetles

Fuller rose beetles spell big trouble as adults, when they like to chew on your rose bushes. You can usually tell they are there by the ragged edges on the roses’ leaves and flowers.

The beetles usually feed at night, when they will chew away at the roses’ flowers and leaves. During the day, fuller rose beetles hide on the leaves’ undersides.

Pesticides typically are not effective in dealing with these persistent beetles. Your best method to get rid of them is picking them off by hand.

4. Thrips

Thrips have a particular fondness to white or light-colored roses. They damage the blooms by leaving brown streaks on the flowers and cause an immense amount of damage. Thrips are a very big problem when the rose bushes are planted close to each other; thrips move easily from one plant to another.

It can be hard to control thrips with pesticides because the pesticides are mainly effective when the insects are in their development phase and are very difficult to see. The best way to get rid of thrips is to clip and throw away the infected flowers.

5. Caterpillars

Some caterpillars love to make lunch and dinners out of rose leaves. Although the damage usually doesn’t threaten the plant, the leaves can look unsightly. Remove the damaged leaves and prune any buds that are damaged.

6. Rose Slug

These insects are actually the larva of sawflies, but look like caterpillars because the rose slugs have legs. You can wash rose slugs off the bushes using a spray of water. One of their natural enemies also may keep them at bay.

7. Leafcutter Bees

These bees make holes in the rose bush leaves and take the leafy material back to their nests.

Although the leaves may not look nice, you really must put up with the bees. There’s no effective way to keep leafcutter bees away from your roses. Bees also are good for the plants because they help with pollination.

8. Rose Curculios

These pests, which are about a quarter of an inch long, start dining as young as larvae on your rose buds as they develop. The rose curculios are particularly fond of yellow and white roses.

Rose curculios eat the buds by punching holes in the buds and blooming flowers. They kill the buds before the buds can even open. You can get ride of a rose curculio infestation by getting an insecticide from a local garden or home center.

9. Flat-headed borers

Flat-headed borers can make the canes of the rose die back, and can kill the canes and the entire plant.

To get rid of the insects, you’ll need to remove any material that has an infestation. You can keep your rose bushes healthy by making sure they have enough water and not overpruning them during the summer.

10. Scale Insects

These pests get their names from the armored scales that they have. Scale insects also like to cause havoc with the cans on your rose bushes.

They may look like small gray ovals, and don’t really move around but you can find them in the front yard or back yard landscape. Because scale insects have no legs, they are there to stay. The best way to try to control them is to prune infected canes and put pesticide oil on any canes that you don’t prune.

House Plants and Pesky Pests

Tuesday, July 29th, 2008

A disease known as “damping off” is a common affliction suffered by plant seedlings in their transition to a new home. A good method to cut down on this is through the use of a sterilized starting mixture, which limits the appearance of this disease. If you notice any of your seedlings have been affected by this, you must remove and discard them to ensure it doesn’t spread to other seedlings.

Another common bane of the average house plant is leaf mold, most commonly found on rubber plants and screw pines. This fungus will also spread if not contained, so affected leaves should be immediately removed and burned. If the disease has already spread too far there may be nothing left to throw out the plant, as it could very well lead to the disease affecting other nearby plants as well.

This rule applies in many instances. Pest infestation especially will often require you to throw away the entire plant. The effort to try and rid the plant of the pests and restore it to good health, coupled with the ever present risk of other plants becoming infected really makes this choice an easy one.

Of course this may certainly be a difficult decision, especially when the plant in question is one you’ve had for a long time, and has become as much a part of your decor as any other piece of furniture or decoration. The good news is that if the pests or disease have not spread overly much, you can still endeavor to save it. The plant should be moved to a new location, away from other plants while you try to bring it back to health. At least in this way you can be certain that no other plants will be infected should the threat continue to grow worse.

Pests, in the form of insects, are one of the most common forms of plant suffering. One of these is the aphid, an insect which usually inhabits the underside of leaves. They come in a variety of colors, which may be difficult to pick up when colored similarly to the leaves themselves. A good spray with water may be enough to remove them, and should be the first step taken in trying to do so. When that fails you can resort to a commercial insecticide instead.

Multiple sprayings will likely be necessary, after which point the remaining few may need to be taken off by hand. This can be accomplished by winding a wisp of cotton around the end of a toothpick and lightly dipping it in alcohol. This creation should easily remove the remaining few who proved resistant to the water or insecticide.

Another form of insects are scale insects, which con in a number of different shapes, sizes and colors. Plants most susceptible to these pests are ferns, ficus tree plant, citrus fruits, ivy and palms.

These hardy pests have a level of immunity to insecticides that makes other methods of removing them more viable. The toothpick method mentioned above is one of the better ways to get rid of these guys, as you’ll be all but forced to remove them by hand one way or the other.

These are just a few of the many pests you may encounter when dealing with house plants. The most important thing is to always keep a watchful eye over your plants to make sure they’re in good health, and take action immediately when anything seems to be awry.

Naturally Say Goodbye to Garden Pests

It’s an unavoidable fact that if left untended, for every flower and plant that adorns our gardens, a greater number of pests will also take root. The good news is that removing these scoundrels from infesting your vegetation does not need to rely on chemicals, nor should it. For each individual species of pest that shows up in your garden abode, there is a natural solution that is cheaper and most importantly, safer to use than pesticides.

Shockingly, North Americans use upwards of 130 million pounds of pesticide each year, both in their gardens and in their homes. This dwarfs the amount used by farmers by almost three times, and accounts for a high percentage of wildlife pest poisonings and contamination of surface water from pesticide use.

Cutting back on this problem requires educating gardeners and homeowners everywhere. Taking the initiative by spreading the word yourself can only help, and the best way to do that is to lead by example, and keep your own home pesticide free.

The following tips will help you keep your garden healthy and pest free without resorting to harmful pesticide use.

The most common problem gardeners will face is insect damage to their plants. With proper cultivation and gardening methods, this problem can be drastically reduced before having to resort to other methods. This means having well-prepared soil, adjusting the pH balance as needed, good drainage and air circulation.

As your garden continues to grow and take shape, remove and dispose immediately of any struggling plants. Be sure to keep your compost area for storing your weeds, discarded plants and compost well away from your main gardening area, as the compost heap will be sure to attract pests.

Keep your garden beds well mulched and top-dressed with compost to ensure healthy plant development. Ensure you’re using clean mulch, bought from a reputable dealer or cultivated yourself.

Be sure to keep your garden area clear of debris and things that will attract insects. If you have fruit trees near your garden, be sure to dispose of any fallen fruit immediately. Spoiled pears or apples will attract all many of pests.

Seaweed fertilizer sprays are useful for strengthening soil and promoting plant growth. They contain helpful minerals and trace elements like iron, calcium, sulphur and magnesium.

Mix up your garden beds with a variety of plant types interspersed throughout. This makes it difficult for plant specific pests to propagate and spread throughout your garden bed.

If you’ve used your gardening implements on infected plants, be sure to sterilize them before using them on healthy plants.

Finally, you can call on the power of nature itself to help you in your fight using a natural product like neem oil. By attracting or purchasing insects which feast upon the particular pests bothering your plants, you can remove them in one fell swoop of natural selection. Praying Mantises, Hover Flies, Ladybugs, Chalcids, Brachonids, and if they don’t frighten you, Wasps, are all insects which will help you battle common varieties of garden pests.

Having a healthy and beautiful garden should not be your number one priority, the health and safety of family should be. Thankfully it is not a choice of one or the other. By using any or all of the above tips, you can keep your garden looking great, and have no fear of your children playing near your plants. It’s truly the best of both worlds.

Cats and Gardens Don’t Mix

Tuesday, May 13th, 2008

by Mike Roberts

You’ve probably spent a lot of time on your garden and the last thing you need is a cat in there digging around. Read below for some tips.

The very first thing you can do when trying to keep cats out of your garden is to make sure that you have your garden boundaries secure. If there are any gaps in your fence (if you use one), you should make sure that you block them to prevent any low access. Cats are very agile animals, and can jump very high. Normally they can jump a small fence, which is why you should also invest in string or taut wire across the top to deter them.

If a cat has made his way into your garden, it may be hard to get him out. Most people choose to use dogs, simply because dogs are known to dislike cats. There are several dog breeds out there that completely dislike cats, such as pit bulls and Dobermans. Cats are completely fearful of these breeds, and will flee if they see them around.

Cats are known to hate water as well. If you spy a cat in your garden, water almost always will get him out. All it takes is a bucket of water or a well aimed squirt with a garden hose to make him think twice about using your garden as his litter box. I have known the real dedicated cat chaser to keep a toy water gun nearby, fully filled for any cat problems.

Protecting your plants is a different story. Mothballs are said to be very effective, as cats don’t like the smell. You can use mothballs around your plants, garden borders, or even along the fence. There are other repellents that you can use as well, such as cayenne peppers, tobacco, lavender oil, citronella oil, mustard oil, and even lemon grass oil. Simply spray a mixture of one of these around the border of your garden.

If you pay a visit your local hardware or lawn and garden store, you can find motion activated sprinklers. They work great in keeping cats out of your garden. Once you install the sprinkler system and a cat comes into the area, the detector will pick up the cat’s presence and immediately shoot out a jet of water that will douse the cat. In most cases, all it takes is a few times of exposure to the sprinkler before a cat learns to stay out of that area.

Sound devices that feature high frequencies are also a great way to scare off cats, although they aren’t annoying to humans. You can find several different models, such as those that stay on all the time, and those that are motion detected. To use this type of device, you’ll need to make sure that the model you have is strong enough to cover the entire area. If you model you are using is strong enough to cover your entire garden, it should suffice in scaring off any unwanted animals.

You can also try commercial repellents to keep cats at bay. Commercial repellents use scents to keep cats away, and shouldn’t be used near any food crops. Due to their high chemical content, commercial repellents can pollute the garden foods that you might eat. You can find them at your local hardware store, with several varieties to choose from, many of which will fend off other critters from your garden as well.

If you have a garden, it can be very annoying if cats and other animals decide to make your garden their home. If you stick to your guns and do your part, you can prevent them from bothering your garden or your crops. Once you have secured your boundaries around the garden, you should try using water first or a fence. If that doesn’t seem to work, you can look into the other methods I have mentioned in this article.

How to Treat Termites

Monday, April 28th, 2008
by John Daily

Oftentimes, Termites can be found dwelling in or near your house. Sometimes overt signs, such as fecal remnants, are hard to notice, so Pest Management Professionals are recommended to determine signs of termite damage. These trained professionals are taught, and deal regularly in regards, to find these lurking critters.

Sometimes, if you are lucky, you can find termites by their droppings that they leave. However, finding termites and their nest are not necessarily equivalent. I know that I have gotten so caught up in trying to kill termites that I forget that there is a nest making termites just as fast as I can kill them. Let us be productive in our endeavors and find out where their nest is. You can do this by knowing the environment that termites like to live in and then parading your property in pursuit of discovering these nests.

Most termites live on pieces of wood or underground. However, at times, some termites can dwell on your property under your real estate. You should consult a professional immediately if you suspect this to be the case.

Subterranean termites are the only termite species that live on top of the soil. They connect to their food through mud tubes. Since they lack eye sight, these tubes serve as an ideal means to find a food source. These pathways can also serve as a way to keep subterranean termites sheltered from natural enemies such as ants.

Termites can also live in dry wood. These types of termites are known as Drywood Termites. They live in the same place that they feast upon, so these termites eat dry wood, live on dry wood, and hence are called Drywood Termites. You can detect signs of their nesting when you notice holes, cracks and leaks in wood portions of the house or other wood objects near you house such as posts and tree trunks. Decayed wood provides essential nitrogen via a fungus that enables these termites to live.

Overall, termites like to live in environments that provide adequate moisture and food. They also need to be protected against harsh weather climate changes. They also need to be sheltered from their enemies as well.

Termite activity is at its lowest during the winter. However, some termites with ideal living environments can continue to unleash havoc on your property during the winter. Even worse, if Global Warming continues to increase, then we will have even more termites surviving the winter. You can use this knowledge to scope out your house property for possible termite locations, but if in doubt, use a professional.

Garden Pests

Wednesday, April 23rd, 2008
by Kim and Charles Petty

If we could garden without any interference from the pests which attack plants, then indeed gardening would be a simple matter. But all the time we must watch out for these little foes little in size, but tremendous in the havoc they make.

As human illness may often be prevented by healthful conditions, so pests may be kept away by strict garden cleanliness. Heaps of waste are lodging places for the breeding of insects. I do not think a compost pile will do the harm, but unkempt, uncared-for spots seem to invite trouble.

There are certain helps to keeping pests down. The constant stirring up of the soil by earthworms is an aid in keeping the soil open to air and water. Many of our common birds feed upon insects. The sparrows, robins, chickadees, meadow larks and orioles are all examples of birds who help in this way. Some insects feed on other and harmful insects. Some kinds of ladybugs do this good deed. The ichneumon-fly helps too. And toads are wonders in the number of insects they can consume at one meal. The toad deserves very kind treatment from all of us.

Each gardener should try to make her or his garden into a place attractive to birds and toads. A good birdhouse, grain sprinkled about in early spring, a water-place, are invitations for birds to stay a while in your garden. If you wish toads, fix things up for them too. During a hot summer day a toad likes to rest in the shade. By night he is ready to go forth to eat but not to kill, since toads prefer live food. How can one “fix up” for toads? Well, one thing to do is to prepare a retreat, quiet, dark and damp. A few stones of some size underneath the shade of a shrub with perhaps a carpeting of damp leaves, would appear very fine to a toad.

There are two general classes of insects known by the way they do their work. One kind gnaws at the plant really taking pieces of it into its system. This kind of insect has a mouth fitted to do this work. Grasshoppers and caterpillars are of this sort. The other kind sucks the juices from a plant. This, in some ways, is the worst sort. Plant lice belong here, as do mosquitoes, which prey on us. All the scale insects fasten themselves on plants, and suck out the life of the plants.

Now can we fight these chaps? The gnawing fellows may be caught with poison sprayed upon plants, which they take into their bodies with the plant. The Bordeaux mixture which is a poison sprayed upon plants for this purpose.

In the other case the only thing is to attack the insect direct. So certain insecticides, as they are called, are sprayed on the plant to fall upon the insect. They do a deadly work of attacking, in one way or another, the body of the insect.

Sometimes we are much troubled with underground insects at work. You have seen a garden covered with ant hills. Here is a remedy, but one of which you must be careful.

This question is constantly being asked, ‘How can I tell what insect is doing the destructive work?’ Well, you can tell partly by the work done, and partly by seeing the insect itself. This latter thing is not always so easy to accomplish. I had cutworms one season and never saw one. I saw only the work done. If stalks of tender plants are cut clean off be pretty sure the cutworm is abroad. What does he look like? Well, that is a hard question because his family is a large one. Should you see sometime a grayish striped caterpillar, you may know it is a cutworm. But because of its habit of resting in the ground during the day and working by night, it is difficult to catch sight of one. The cutworm is around early in the season ready to cut the flower stalks of the hyacinths. When the peas come on a bit later, he is ready for them. A very good way to block him off is to put paper collars, or tin ones, about the plants. These collars should be about an inch away from the plant.

Of course, plant lice are more common. Those we see are often green in colour. But they may be red, yellow or brown. Lice are easy enough to find since they are always clinging to their host. As sucking insects they have to cling close to a plant for food, and one is pretty sure to find them. But the biting insects do their work, and then go hide. That makes them much more difficult to deal with.

Rose slugs do great damage to the rose bushes. They eat out the body of the leaves, so that just the veining is left. They are soft-bodied, green above and yellow below.

A beetle, the striped beetle, attacks young melons and squash leaves. It eats the leaf by riddling out holes in it. This beetle, as its name implies, is striped. The back is black with yellow stripes running lengthwise.

Then there are the slugs, which are garden pests. The slug will devour almost any garden plant, whether it be a flower or a vegetable. They lay lots of eggs in old rubbish heaps. Do you see the good of cleaning up rubbish? The slugs do more harm in the garden than almost any other single insect pest. You can discover them in the following way. There is a trick for bringing them to the surface of the ground in the day time. You see they rest during the day below ground. So just water the soil in which the slugs are supposed to be. How are you to know where they are? They are quite likely to hide near the plants they are feeding on. So water the ground with some nice clean lime water. This will disturb them, and up they’ll poke to see what the matter is.

Beside these most common of pests, pests which attack many kinds of plants, there are special pests for special plants. Discouraging, is it not? Beans have pests of their own; so have potatoes and cabbages. In fact, the vegetable garden has many inhabitants. In the flower garden lice are very bothersome, the cutworm and the slug have a good time there, too, and ants often get very numerous as the season advances. But for real discouraging insect troubles the vegetable garden takes the prize. If we were going into fruit to any extent, perhaps the vegetable garden would have to resign in favour of the fruit garden.

A common pest in the vegetable garden is the tomato worm. This is a large yellowish or greenish striped worm. Its work is to eat into the young fruit.

A great, light green caterpillar is found on celery. This caterpillar may be told by the black bands, one on each ring or segment of its body.

The squash bug may be told by its brown body, which is long and slender, and by the disagreeable odour from it when killed. The potato bug is another fellow to look out for. It is a beetle with yellow and black stripes down its crusty back. The little green cabbage worm is a perfect nuisance. It is a small caterpillar and smaller than the tomato worm. These are perhaps the most common of garden pests by name.
