<p>I am staying at a friend’s this weekend, a tri level. Some catching up on laundry has me on all four levels. The house seems unusually hospitable to spiders and to some extent so are the locals.</p>
<p>There are two questions: What is making these spiders flourish? There are almost no other insects apparent but for very tiny flies here and there in a web. No fruit flies. The other question, being averse to using toxins, what less drastic measures might dampen the arachnid enthusiasm for the place?</p>
<p>Measures? I’ve got two - one calico and one white! They pounce on anything that scurries across the floor. I have not seen a spider inside my house in ages.</p>
<p>“What is making these spiders flourish? There are almost no other insects” - It’s not likely that the spiders have bloomed all at once. More likely that they have just been undisturbed. A vacuum with a hose and crack and crevice tool will help you with do wonders to reduce the population immediately.</p>
<p>LOL - cottonwood513, I didn’t think you were really their next meal. Spiders that bite humans are often just trapped or disturbed by them trying to get away.</p>
<p>I love having spiders in the house… because as a result I don’t have the insects I really dislike, like mosquitoes and flies. Spiders pretty much stay put!</p>
<p>We are on the same latitude and are having our annual autumn spider invasion. I think they want someplace warm to lay their eggs instead of freezing to death. (This is not an expert opinion!)</p>
<p>DMD, that’s about how I feel about them at home. Just stay in the basement.</p>
<pre><code> It’s been unseasonably warm this October, in Chicago. I think you are right about laying their eggs before winter, I never saw so many egg cases as in the laundry room here.

<p>I should have mentioned that I do NOT like wolf spiders. They don’t have webs and they are roving predators that actually pounce on their prey. ([Wolf</a> spider - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Wolf_spider]Wolf”>Wolf spider - Wikipedia)) I taught in a school that had wolf spiders for a while—that was pretty bad. Just try to calm down a class of high schoolers when a one-inch diameter wolf spider is running across the wall.</p>
