Questions people ask
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.
Is a spider bite what I think it is?
Often not. Many 'spider bites' are really other insects or skin infections. See a doctor if a bite spreads, blisters or hurts badly.
Do brown recluses live in my area?
In parts of Texas, yes. They're less common here than further into their range. Get a suspect spider identified before treating.
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.
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. Across McAllen, most things people call spider bites are not, as Suchard's 2011 emergency-department study found when only 3.8% of 182 suspected cases from 2006 to 2007 were confirmed as spider bites. It's worth looking for the spider before blaming one. A good pro in McAllen will explain how their plan fits what they found at your home.
