Any creepy crawly thing with six legs is an insect. They share similar life stages, going from egg to larva to adult. Of course, from your point of view, spiders are bugs, too, even though they're not insects, but arachnids.
Control What's Bugging Your Flowers, Shrubs, and Trees
Your landscaping looks beautiful. To many bugs, it looks like lunch. All sorts of bugs stop by to feast on your trees, shrubs, and flowers. Some fly, some crawl, and some dig around underground. Not all of them are harmful. Ladybugs, for instance, gobble up pest bugs. Don't try to eradicate all of your pests, since you never will,but you can effectively control them easily with contact or systemic bug controls.
Learn About Your Bugs
You have your flying bugs, your crawling bugs, your stay - in - the - ground bugs. Not all are bad. Ladybugs, and praying mantises eat some of the bugs that eat your plants. Bees help pollinate many of your flowers, shrubs, and trees. Bugs also attract birds, which eat all sorts of bugs, too. Be careful to keep the good guys in your garden while you control the pests.
There are two types of products used for controlling insects in the landscape. Systemic bug controls are absorbed by the plant and kill insects when they feed. Systemic controls, like Ortho® Tree & Shrub Insect Control Granules work well on bugs like scale that form a tough coating over themselves protecting them from many contact controls. Contact bug controls kill bugs when they come into contact with it, either directly by the spray or by the residual left on the surface of the plant. That's how Ortho® Bug B Gon® Insect Killer for Lawns & Gardens works on over 200 types of bugs.
