Questions people ask
Do brown recluses live in my area?
Probably not. Utah is outside the brown recluse range.
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.
How long does spider treatment take to work?
You'll usually see fewer within a week or two. Webs and egg sacs need clearing too, or new spiders hatch.
Should I use a fogger or bug bomb for spiders?
No. Foggers don't reach where spiders hide. They can also be a fire risk if used wrong.
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.
Was it really a spider bite?
Probably not. Three point eight percent of the 182 patients who came to one California emergency department with a suspected spider bite between 2006 and 2007 actually received a spider-bite diagnosis, according to Suchard's 2011 clinical study.
