This meant that insects did quite well at the start of the season.  Spiders mainly eat insects (and each other, of course) so that meant that the first generation of spiders had a higher success rate than usual.  After that, the compound interest effect kicked in so now, by the end of the season, it is said that many homes in the Twin Cities and greater Minnesota are loaded with the tiny eight-legged creatures.  <\/p>\n<p><H3 style=\"color:black;\">Is it bad to have so many spiders?  What if a spider bites me???<\/H3><\/p>\n<p>Keep in mind that the reason there are so many spiders in your house is that <!--more--><\/p>\n<p>there were a lot of insects for these spiders to eat. So, for every spider you see now, there were a whole bunch of insects that got eaten.  So, one could say that it is a good thing that there are a lot of spiders in your house!<\/p>\n<p>Spiders don&#8217;t bite people very often.  There is a belief that spiders come into your bed and bite you during the night. People who wake up with large red welts that itch or hurt may think that they were bitten by a spider.  The rule of thumb, it seems, is this: A small welt that itches for a while then goes away was a mosquito, and a larger welt that lasts a long time is a spider.  This is not true.  Most likely both are mosquito bites, but the smaller welt is from an unsuccessful mosquito bite where you chased the mosquito away or mushed it before it got finished with you, and the larger welt is from when you were sleeping and a mosquito had a nice, full, complete, slow, delicious blood meal at your expense.  A spider did not sneak into your bed and bite you.  They don&#8217;t do that.  (I quickly add that your large uncomfortable welt could have been something else besides a mosquito, but not likely a spider). <\/p>\n<p><strong>See Also: <a href=\"https:\/\/gregladen.com\/blog\/2017\/10\/truth-brown-recluse-spider\/\">The Truth about the Brown Recluse Spider<\/a> <\/strong><\/p>\n<p>People just say that it was a spider bite because they are more creeped out by spiders than they are by mosquitoes, so the mosquitoes get blamed for the smaller bites and the spiders get blamed for the bigger bites.  <\/p>\n<p>One downside of having a lot of spiders is, of course, having a lot of spider webs, also known as &#8220;cobwebs.&#8221;  (Word Origin: the word &#8220;cob&#8221; comes from an old word for spider dating to when Dutch and English overlapped more, which is why it sounds Dutch: Coppe.)<\/p>\n<p><H3 style=\"color:black;\">OK, so how to get rid of spiders<\/H3><\/p>\n<p>Most sources will tell you to start by sealing off all the cracks in basement walls and window casings. Fine, go ahead.  It might be, though, that those cracks are where the spiders might hang out and thus be invisible to you, which is the same as getting rid of them, right?  In any event, whether or not you can do this depends on where you live. For most of my life before moving to the Midwest, I lived in houses that were between 100 and 200 years old.  Forget about sealing cracks in places like that.  But if you live in a modern home it might be possible.  So get out the caulk and get sealing.<\/p>\n<p><strong><br \/>\n___________________<\/p>\n<p>Check out: <a href=\"http:\/\/ikonokast.com\/\">The IKONOKAST Science Podcast.

Spiders keep their bodies up off the surfaces they are crawling on.  But, getting rid of the insects will reduce your spider population because you are starving them out. Personally, I don&#8217;t like using insecticides.  They are icky and smell bad and it amounts to spreading a poison around in your living space. So go spray some around if you want, but wait a week or two to invite me over, please!<\/p>\n<p>A common piece of advice is to make sure your house has very little stuff, like boxes or storage containers or furniture or drapes etc. where spiders can hide behind.  This advice amounts to telling you to get rid of all your stuff.  So go ahead and do that and you&#8217;ll have fewer spiders.  I don&#8217;t think you are doing to do that, though. <\/p>\n<p>Another piece of advice is to cut down the bushes and trees near your house.  Seems a bit extreme to me. It is a good idea to cut back plants that would shade a burglar who wants to spend some time breaking into a particular window or something.  You could just get a dog, though.  The dog will need to be fed, however, and the food will attract and nourish insects, then that will cause you to have more spiders.  And, the dog will have fleas and you&#8217;ll get the occasional flea bite and blame the spiders, and then you will think you have more spiders than you do, which will produce the opposite effect we are going for here.<\/p>\n<p>OK, ok, so all these methods and other methods you see on the internet don&#8217;t work, or have undesirable side effects.  So what is the point? Is there nothing you can do?  Of course there is, and I told you a major clue at the beginning of this blog post!  <\/p>\n<p><H3 style=\"color:black;\">So, how do I get rid of the damn spiders, then, smartypants? <\/H3><\/p>\n<p>You can&#8217;t get rid of them but you can reduce their numbers.  Here&#8217;s how:  Get a vacuum cleaner and go all around your house in the spring, after the insects and spiders have started to become active (which depends on where you live) and vacuum up all those nooks and crannies using the wand attachment.  Make sue you have a good vacuum and the bag is empty and all that so you have good suction.  Vacuum the ceiling of your basement, all the corners, around the molding (don&#8217;t forget over the door frames) and behind furniture, under the couch cushions (including in the deeper often missed recess of the couches and overstuffed furniture). Turn the furniture over &#8230; all of it &#8230; and vacuum underneath.  Don&#8217;t just reach under your dining room table: Get  on your back like you were changing its oil and vacuum out every little nook and cranny up under there.  <\/p>\n<p>Obsessively, compulsively, suck up every bit of dust everywhere in your house, and that will get rid of 99% of the extant spider, insects, eggs, egg sacks, and even the food may various insects will eat.  Well, not really.  There are entire categories of insects or other creatures that are too small to see and that can&#8217;t really be vacuumed, that that you&#8217;ll probably miss, like the mites that live on your cat&#8217;s eyebrows.  And your eyebrows.  Nonetheless, if you give your house a very very thorough vacuuming and cleaning you&#8217;ll stop that first generation of spiders form doing well. The remaining spiders, or the ones that sneak into your house later on, will not have the head start they usually have, and as each generation grows and grows in number they will not achieve the large population they other would have.<\/p>\n<p>Yes indeed. Compound interest works both ways!<\/p>\n<p>One final piece of advice:  Most people do not seem to realize that many biological phenomena occur in cycles spanning several years.  Is that oak tree especailly annoying with its acorns this year?  Well, they only do that every few years &#8230; for a reason &#8230; and you may not have noticed this. The mistake many make is to take the worst year and use that as their benchmark. The truth is that if you have a lot of spiders in your house all of the sudden, this does NOT mean that your house has made some sort of transformation from a house in which there are hardly any many spiders to one overrun by them and will thereafter be spider-house.  No. Most likely you have experienced a simple natural cycle and if you do nothing, there will  be fewer the next year. My advice &#8230;. to relax about the spiders but do a major hit on their numbers early in the year using the basic organic and safe technique of vacuuming everything up &#8230; will reduce the amplitude of those cycles so low-spider years will seem spider-free and high-spider years will be not as annoying.  And it is all about the perception of spiders and not how many spiders there actually are.  Because you can&#8217;t really get rid of them. <\/p>\n<p>(If you&#8217;ve got kids, you could always teach them to catch and release the spiders, like they do <a href=\"http:\/\/www.wildlifefun4kids.com\/2013\/05\/15\/catching-a-spider-catch-and-release-for-kids\/\">HERE<\/a>!)<\/p>\n<h5>Photo of spider by Greg Laden.
