Other Insect Information

Guidelines for submitting an insect to the Entomology Lab:

Residents are encouraged to submit unfamiliar insects to the lab for identification. These samples are often how AWM personnel become aware of exotic pests in San Diego County.  Please submit clean, intact samples, preserved in alcohol if possible. If not, a small container will do. Avoid submitting samples on tape, or which have been squashed.

Bring the sample to one of our offices and fill out a Specimen For Determination form. Click here for office addresses and phone numbers. You may also print out a form and mail it, with the sample, to either office.

Please allow 2 weeks for determination. The results will be mailed to the address you provide. Please ensure that you have COMPLETELY and LEGIBLY filled out the address portion of the form.

If you suspect you have Red Imported Fire Ant, please call (800)200-2337 to request a RIFA submission kit.

Please also be aware that our Lab does not currently have the specialized equipment or staffing expertise to respond to issues associated with pet or human health. Please contact your local veterinarian or health care provider in these instances.
