We don't often find flies such a popular topic of conversation, but given recent events, we'd like to seize the moment to share some science-based information about their status as both pests and beneficial insects.
Flies can be nuisance insects both indoors and outdoors. There are many species of flies in California with some being more problematic than others. In UC IPM's publication Pest Notes: Flies, the authors provide information about identification, habitat, damage, and management of several common flies including house flies and face flies.
You may be surprised to learn that some flies are actually beneficial insects. Many flies in the...

While you are home working, learning, or relaxing, you may have noticed a few other critters sharing space with you. If some of these critters have 8 legs, we have a video to show you how to catch and release them!
Why might you release spiders outside? Spiders are beneficial insects called natural enemies. They are predators that help control other pests and insect eggs.

Beneficial insects can provide a lot of support in the garden. Natural enemies, which include predators, parasites, and pathogens, reduce pest populations and can help prevent damage to plants. Pollinators such as honeybees, native bees, butterflies, beetles, and other insects are essential for many vegetables you may be growing.
You may not have noticed many of these parasites, pathogens, and predators that help control pests in the garden, but they are there! Lady beetles (ladybugs), lacewings, and predaceous ground beetles are some common predators that you may find in your garden.../h2>
This Saturday, April 13th, is the annual Picnic Day celebration at UC Davis.
Join the UC Statewide IPM Program from 9am to 3pm at the entomology building Briggs Hall on the UC Davis campus. We'll have lady beetles (ladybugs) to give away, information on beneficial insects, stickers and temporary tattoos. Plus, this is a great time to get your pest questions answered and learn about the UC IPM resources available to the public.
Praying mantids are well-known predators we often see lurking around gardens, landscapes, and sometimes near porch lights, waiting for a tasty meal to arrive.
Praying mantid adults are 2 to 4 inches (5-10 cm) long and are usually yellowish, green, or brown. Mantids (often referred to as praying mantis) go through incomplete metamorphosis (egg, nymph, adult) and have one generation per year. Overwintering eggs are laid in groups in hard, grayish egg cases which are glued to wood, bark, or other plant material. Adults and immatures (nymphs) have an elongated thorax and grasping forelegs, which they have the...
