spray more in the future. Also, insects benefit your garden by pollinating your plants, helping them grow and propagate.
Good Bugs and Bad Bugs Not all insects are pests, and some are actually beneficial to your home and garden, because they are predators to specific pests and prevent them from becoming a problem. This Pocket Guide describes some common beneficial insects found in Kentucky, (and other states), and offers a pictorial guide to aid in identification.
How to make your good bugs feel welcome - Beneficial insects are more likely to remain in your garden if there is a ready food supply. While you can buy many of these predators, it's probably cheaper and more effective to encourage the ones already in your garden. Many beneficial insects need to sip flower nectar to survive. Plan your garden to feed beneficial insects by choosing a variety of plants that will bloom as many months of the year as possible. Here are some things you can do to support your beneficial insect population: • Plant nectar-producing flowers to further increase the food
supply. Plants in the cabbage, carrot and sunflower family are especially attractive to beneficial insects.
There are over one million kinds of insects, divided into thirty different groups, called Orders. So as to simplify this guide, we have ignored most scientific classifications, and instead grouped insects, mollusks, and other arthropods, (bugs, slugs, and eight-legged creatures), into general groups that exhibit a set of characteristics. Why is it important to recognize bugs that help us in the garden and those that do no harm? To use a pesticide effectively, one must carefully select an insecticide that is targeted for the specific pest. In using a pesticide, often other bugs-- those that do no harm to the garden, or may even kill the pest-- are harmed. To reduce the use of pesticides, pay close attention to actual bug that is a nuisance. In many cases, if you can wait, or use a non-chemical control targeted for the specific pest, nature will allow these bug predators into your lawn to naturally remove the pest.
• Control ants, which may prevent predators from controlling aphids.
• Don't use persistent, broad-spectrum, contact insecticides. These provide only temporary pest control and are likely to kill more of the natural enemies than the pests. When their enemies are gone, pest populations may soar and become more of a problem than before they were sprayed.
• Cover bare dirt in your garden with mulch of dead leaves or grass clippings, thick enough to shade the soil surface. This provides shelter for spiders, which are the number one predator on insects. (Most of these spiders are tiny.)
We would like to attribute many of the photos, text, and general information to the University of Kentucky’s Department of Entomology Critter ID and ENTFacts section of their web site. We would also like to thank the University of Kentucky’s Cooperative Extension Service for their advice and aid in developing this Pocket Guide.

Don't forget the birds - Birds can also be very helpful with controlling pests in your garden. Trees, shrubs with berries, birdhouses and water features all encourage birds to visit your yard. Bug-eating birds include Bluebirds, Cardinals, Grosbeaks, Nuthatches, Orioles, Sparrows, Swallows, Titmice, Warblers, and Woodpeckers.
Beneficial and benign insects are listed as bugs that crawl, those that fly long enough to get from one plant to the next, those that hop, and those that fly. This is not a complete listing, but a

The concept of a pest is based on human purposes and perceptions. Under this criterion, a pest is an organism that has characteristics regarded by humans as injurious or unwanted.
Usually, an organism is identified as a pest because it is harmful to agricultural activities or the ecosystem, or carries germs within human habitats. Examples include those organisms that vector human disease, such as rats and mosquitoes. The term may also include fungi and viruses.
How to Promote Beneficial Bugs in Your Garden Think before you spray a pesticide - You may kill the insects that are helping you keep pests in check. This means you will have to
