Need to know what keeps bitting my wife !! Please help we already had an exterminator come over and spray And bomb and still getting bites!
Unfortunately it is impossible to id the cause of skin lesions from their appearance alone because many things can result in very similar lesions, everything from actual bites to food or contact allergies. Plus people react differently to different things. Here's a list of insects and mites that bite http://www.livingwithbugs.com/unknown_bug_bites.html but I'd urge you to also consider the possibility that some other agent may be the cause. Sorry I can't be more specific.
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
20 years as university extension entomologist, now retired; currently publish a website about home and garden insects.
