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.

Natural enemies, also called beneficials or biological control agents, include lady beetles (ladybugs), lacewings, spiders, parasitic wasps, and even some mites! These natural enemies feed on pests in the garden and landscape and may reduce the need for insecticides.

Here are some things to consider if you decide to try lady beetle releases:
