Question Greetings. I have a bad flea infestation and want to bomb my place but do not want to kill the spiders living here. I will be leaving town for a week so any treatment is acceptable. Are there any products/substances that will kill fleas but not harm arachnids? Thank you!
The best way to control fleas is with topical flea meds like Frontline or oral meds like Capstar (see http://www.livingwithbugs.com/fleas.html for details), these won't harm the spiders. Flea bombs in fact do not work well.
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.
