Just because a bug is a bug, doesn't mean it is also a pest. In fact, rather than being pests, most insects are actually garden helpers. You don't want to destroy the best fighters in your garden army. Do not go around killing every bug you see. First ask the question, "Friend or foe?"

To increase the effectiveness of your garden fighting force you may need to get reinfocements. Beneficial insects can be purchased in huge numbers from good garden catalogs or home and garden stores. These include lace wings (in larvae form), praying mantis (in egg cases), predatory wasps such as the Trichogramma, and ladybugs (also called lady beetles).

Besides encouraging the habitation of beneficial insects in your yard and garden, you also need to protect plants, including fruit trees, from the ravages of destructive pests

Apple Maggot can cause the fruit on an apple tree in a yard to be inedible and unsprayed trees pose a very serious threat to neighboring orchards. The primary host for Apple Maggots is Hawthorn and Apple trees although it is reported that Apple Maggots have been found in Crab Apples, Plums, Apricots, Pears, Cherries, and wild Rose Hips. A female Codling Moth can lay over 100 eggs on foliage or on the fruit itself. When the worms hatch they eat into the fruit and destroy it. Other pests and diseases of concern include Cherry Fruit Fly, San Jose Scale, Pear Psylla, Pandemis and Fire Blight.

How to Care for Your Backyard Apple Trees and Host Ornamentals to Protect them from Apple Maggot

The Kittitas County Pest Board reminds owners of horticultural property of their legal responsibility to properly care for and treat their fruit trees. If you have fruit trees or host ornamentals growing on your property, the commercial fruit growers in our county are asking for your cooperation in controlling destructive horticultural insects. Every landowner (including the city municipality) has a duty to control pests and diseases on private and public property under the Laws of the State of Washington. There are a multitude of destructive pests and diseases that could potentially attack fruit trees.

Two examples of pests that you should pay primary attention to on apple trees are Apple Maggot and Codling Moth. Before you plant any new fruit trees in your yard, or if you have any existing fruit trees on your property, be sure that you understand and are willing to accept the responsibilities that go along with owning them. You must be able to give them the special attention that they need throughout the year.

The sure way to control pests and diseases on your fruit trees is to spray them with insecticides and other products. This usually requires one early spray plus as many as eight or more cover sprays depending on what products you use.

If you do not have the equipment to do this you will need to hire a reputable pest control spray service. Tree or fruit removal is an additional option. If you do not take care to eradicate pests and diseases affecting fruit trees and host ornamentals that you own, they can spread to a neighbor’s backyard tree or travel to commercial orchards where they can cause serious economic damage.

In order to start your pest control program you need to spray on a regular schedule. You can obtain information on pesticides and timing of sprays from WSU Cooperative Extension Bulletin 1928 titled Protecting Backyard Apple Trees from Apple Maggot. Another option would be to simply not plant new trees and remove existing fruit trees to avoid the costs of purchasing special spray and equipment or having to pay a commercial pesticide applicator several times per season. If you do decide to plant or keep existing fruit trees on your property, be aware of your responsibilities of ownership and take care of your trees.
