Why Are Spiders So Bad This Year?

At least 3 times in the last week I have had customers call and ask this question, "why are spiders so bad this year"?  Look, nobody likes spiders and it seems that they are out this year in higher numbers than in years before, so the question is "why"?  Is there something that is causing their population to increase or are we all just imagining it?

First of all, I think that I hear this every year, so I don't think the spider population is suddenly much higher this year.  However, it is a little bit higher than it has been in the past, so let's review the reasons why your home might suddenly be crawling with giant, hairy, disgusting eight legged freaks!

#1- Mild Weather Last Winter
We kind of saw this coming because of the mild winter that we just had.  Inclement weather greatly reduces the spider populations and we did not have much of it in the Puget Sound area this year.  It never really got all that cold and there wasn't much in the way of snow and ice, so spider populations carried over a bit.

#2- More Food Sources
Not only did more spiders survive our mild winter, but a lot of other insects survived as well.  This means more food for spiders and with more food, comes a higher rate of reproduction.  Remember, spiders are not all bad and they do keep other insects from getting out of control because they eat them all.

#3- Humidity
Remember how hot it was a few weeks ago?  Well, over the last few days we have seen a lot of rain and combining this with the heat creates humidity.  Insects thrive in humid climates and this only adds to my last two points.  The weather is creating an ideal environment for all pests (including spiders) and their food source has also increased.  This makes for a bad combination if you really hate spiders.

#4- Normal Seasonal Changes
As our summer winds down and it starts to cool, you can expect more spiders getting into your home to escape the cold.  October is generally the worst month for spiders (judging by the number of spider treatments we do as a pest control company throughout the month).  Usually by December there are fewer and fewer spiders and then February is the month where many of the eggs start to hatch.  So, if you are seeing a lot now, it might get worse soon.

If you want to get this under control quickly, just give me a call and I will gladly provide a pest control solution for you.
