The cockroach has two long antennae, 6 legs, and two small protrusions from its back end. The mite has a few white lines showing what the squiggly digestive tract looks like inside the mite. The mite has 8 legs - two pairs are on the front end of its body and two pairs are on the back end.

Is something bugging you? District entomologists can help identify insects and provide information on whether the insect is harmful and how to control it. Samples can be submitted in the following ways: 

  • Email us a photo - You may email photos to Not all insects can be identified from a photograph, so save the sample in case we ask you to send it in later.  (Read these tips on taking a photo that we can use to identify your pest.)
  • Drop off a sample - Bring a sample by the District office anytime we’re open. Please read the recommendations and restrictions below before you bring a sample.
  • Submit a service request - We can pick up a sample you have collected if you fill out our online service request form.
  • Just curious or want to learn how to identify on your own? - Read more here about how to identify insects, including some great resources.
