Entomology (Study of Bugs)/Bug indentification



Hi there! I keep seeing these late at night on my bathroom floor. I was finally able to catch some. These are ones I killed via drowning them in big spray. They are young bugs I'm pretty sure because they even smaller than this last time I saw them.

Hi, Ashley:

Thank you for including the images with your question.

I am pretty confident these are nymphs (juveniles, immatures, "babies") of some kind of cockroach.  German Cockroach is the most likely suspect, as other species are much, much larger.

I would stop using "big" spray (I'm sure you meant to type "bug spray"), and seek a professional pest control company that uses *baits* to control roaches.  Baits are generally much less toxic to people and pets, leave no residue, and are much more effective at eliminating roaches than any other kind of treatment.

You could also buy over-the-counter baits to use yourself, but PAY HEED TO THE DIRECTIONS AND WARNINGS.  Some baits should not be used by women, especially if they are pregnant or may become pregnant.  That is why I recommend using a reputable professional, preferably a local one with an "A" rating or higher from the Better Business Bureau.

Best wishes to you for a swift and complete resolution to the roach problem.  I do believe that the potential dangers posed by roaches are a bit inflated, but at the very least they are a disconcerting presence.  I know from my own experience.

Take care, feel free to ask any follow-up questions.

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.
