Entomology (Study of Bugs)/Unknown Insects on Glue Traps


Any idea what these are, finding tons of them on the glue traps we set out to catch recluses.

Adonis (seriously?),

Thanks for including the image with your question.  Those would be "springtails" in the order (or class) Collembola.  Most scientists now consider springtails to be "non-insect hexapods."

Springtails are moisture-dependent, so wherever you are trapping them, that room likely has humidity or moisture issues.  Springtails feed mostly on decaying organic matter, but probably graze on mold and mildew spores as well.  The best (only?) way to control them is by thoroughly drying the area where you find them.  Consider a de-humidifier, for example.

Springtails are *not* a threat to the health of people or pets, or to property, as far as I know.

Oh, and not all species of springtails....spring.  Some lack the jumping organ.

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.
