IDPH entomologists accept specimens (insects, spiders, ticks, etc.) for identification from Illinois residents.
1 Submit specimens in leak-proof, crush-resistant containers. If possible, do not tape or glue specimens.
2 Certain specimens (e.g., ticks, insect larvae) should be in 70% ethanol or isopropyl (rubbing) alcohol.
3 Mail specimens in crush-proof containers (plastic vials, med/specimen bottles, boxes, etc.) sealed inside plastic bags.
4 Specimens will be identified, but not tested for the presence of pathogens or disease.
5 Most specimens are identified and a written report mailed the same day they are received.
