Questions people ask
Do spider sprays actually work?
Store-bought sprays kill what they touch. They rarely reach hiding spots. Removing webs and egg sacs and sealing gaps works better.
Why are there suddenly so many spiders in fall?
Males wander in late summer and fall looking for mates. Many end up indoors by accident. It usually settles down in a few weeks.
Why do spiders keep coming back after I clean?
Usually because the insects they eat are still around. Egg sacs and gaps around doors also keep them coming.
Are the spiders in my house dangerous?
Almost always no. Most house spiders can't hurt you. Widows and recluses are the main exceptions in the U.S.
Will treatment get rid of all the spiders?
No, and that's fine. The goal is fewer spiders indoors. A few outside help control other pests.
Why do spider bites often turn out to be infections?
For Miramar homes, eighty-five point seven percent of the 182 patients with suspected spider bites in Suchard's 2011 study of one California emergency department, seen between 2006 and 2007, were diagnosed with an infection instead.
Does every house have spiders?
Nearly, based on the best available room-by-room study. In the 2012 study by Bertone and colleagues, entomologists searched 50 volunteer homes in North Carolina room by room and found spiders in every one, which shows how common spiders are indoors.
