Many different kinds of insects are found in and around our homes, yards and fields.  Most of these insects are completely harmless and do provide a valuable service for us.  We refer to these insects as beneficials.  The majority of beneficials fall into two general categories: parasites and predators.  Parasites are usually the immature or larval stages of wasp and flies.  Predators are commonly larger than parasites.  Predator insects actively seek and capture pest insects.

A parasite insect kill only one host during their life while a predator will kill and eat many prey.  Some common beneficial insects are the lady beetle, lacewings, Assassin Bug, Syrphid flies and Damsel bugs.  It is important that we pay attention to beneficial insect populations before we apply an unnecessary insecticide application.

Beneficials can keep pest numbers in check however when pest population levels reach the economic threshold, we have to treat to protect our investment.
