Organic Backyard Care - Insects
Insects-- how to balance the helpful insects with the invasive, destructive ones organically.The rewards of increasing your "organic" activities and decreasing your "chemical" activities are great. You have less cost, easier maintenance, and a much healthier environment in which to work and play.
Here are a few tips on how to "think organic" about insects that are common backyard residents.
Organic Insect Control
By following good yard care practices, you will have a good head start on eliminating the conditions that would invite insects to your yard.
The key to effective control of a pest insect is correctly identify the insect. This will help you determine the appropriate measures to take to control or eliminate it.
You need to be aware of insect feeding cycles. For example, early detection of sod webworms is essential for successful control since the damage is already done by the time it becomes evident when you find small one to two inch spots becoming large dead patches. Keep a lookout for the buff-colored moths starting in mid-spring. If you see them, expect a caterpillar problem in a few weeks.
Mechanical Insect Control
Pheromone traps contain odorous substances emitted by insects for thepurpose of communicating with others of the same species. Trapping maybe done to either monitor or control insect populations. Pheromone-baited traps are on the market for many pests. For example, Japanese beetletraps use scented lures to attract beetles to a hanging bag into which they fall and can't get out. They are very effective, so much so that they will encourage beetles to visit your yard and can attract beetles from as far away as a quarter of a mile.
Easy when you know what you're looking for and can detect an insect problem early. Get to know the signs of insect damage and the lifecycle of the lawn pests in your area to have an idea of when you need to be on the lookout. For example, if you see a patch of lawn turning brown, check to see if the sod pulls away easily and check for root feeding insect grubs.
When white grubs migrate toward the soil's surface they are vulnerable to spiking tools. This is usually in late spring as they prepare to turn into beetles and again in August and September as they just hatch from eggs. Sharp spikes that penetrate at least two inches into the soil impale and kill grubs. Special shoes with spikes attached to the bottom are now available. A hand-spiking tool also will do a good job.
Ground fossilized shells into a fine, talc-like powers that can be handled safely without gloves and can kill insects on contact. It is not a poison, butworks mechanically by piercing an insects exoskeleton dehydrating and killing it when comes into contact. To kill grubs, cutworms and other larval lawn pests, dust four times a year, using 25 pounds per 1500 square feet. Helpful insects, however, such as Ladybugs, praying mantises, honeybees and the larvae of parasitic wasps are also vulnerable.
Biological Insect Control
Unlike the harmful root knot nematodes which attack plants, beneficial or predatory nematodes only attack pest insects in the soil. These naturally occurring organisms will control a large number of grubs and larvae of pest insects and eggs of beetles and weevils.
Another way to control insect populations is to attract birds to your yard. Plant trees to encourage nesting or provide bird houses and shrubs that produce berries, such as Honeysuckle. Birds are also attracted by birdbaths and feeders.
Maintenance Insect Control
Environmental stress may trigger pest infestation no matter how healthy your lawn is. Your lawn has a better chance against insect infestation if you eliminate stress by using healthy lawn practices such as proper mowing, watering, fertilizing as well as removing excessive thatch.
Long term prevention of attacks from insects such as sod webworms, billbugs and cinch bugs can be warded off by eliminating excessive thatch where they live. Remove thatch by raking and prevent thatch buildup by using a top dressing of organic material on a yearly basis to provide the microbes that naturally feed on thatch. Since sod webworms prefer turf that is dry and warm, water in the late morning and cut grass no shorter than 2 inches to keep the lawn cool. Topdress it with a one-fourth inch layer organic material such a peat moss or sifted compost each year to control the buildup of thatch.
Eliminate compacted soil Check your soil for signs of compaction and a deficiency in organic matter. Aerate soil to eliminate compaction and reduce thatch. Correct these conditions for long-term control of ants.
