There are many people out there who think the only good bug is a dead bug. We all know about honeybees and lady bugs, but there are numerous good bugs out there, and you will want to encourage them. Many occur naturally in your garden and can monitor and contain pest problems. Catalogs are available where you can purchase these beneficial insects, but make sure you need them before you order. Many have specific food or insect needs.
Ladybugs are great aphid hunters.
You can incorporate all the ladybugs in the world, but unless you have aphids, they won t stay in your garden, they ll move on to find some food. Ladybugs, everyone can identify, or so they think. But the larval stage of a ladybug is every bit as desirable as the red-spotted adult, yet they look nothing like a mature ladybug. The larvae look like tiny black alligators with orange or blue spots on the back which is covered in spines. Both are useful if aphids are a problem.
