Entomology (Study of Bugs)/Mystery Bug.


Small bugs
Small bugs  

I live in Central Minnesota in an apartment and I have been seeing  these little guys around my kitchen, bathroom and occasionally in my living room. They look like thy have wings but don't seem to fly, only crawl around during the day. Any ideas as to what they are and if I need to call an exterminator?


Hi, Jess:

Thank you for including the very nice image with your question.  I know how tiny those are, great job!

The insects are "Saw-toothed Grain Beetles," Oryzaephilus surinamensis .  Here's more about them, their management, control, and prevention:



http://www.extension.umn.edu/garden/insects/find/insect-pests-of-stored-food/ from U of Minnesota, addresses most "stored product pests."

No exterminator needed.  Simply find the infested product(s) and discard it (them).  Store vulnerable foodstuffs (including dry pet food, birdseed) in glass, metal, or durable plastic containers with tight-fitting lids.

Good luck!

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
