It’s also under your sofa, beneath your appliances, and in your coat closet. It’s in that crack by the front door. No silly, the one under the baseboard.
House spider mating season is here. “They got a thing… goin’ on.”
There are three local species of house spiders: Tegenaria agrestis, also known as the Hobo Spider, Eratigena atrica, the Giant House Spider, and Tegenaria domestica, the Domestic House Spider.
These closely related spiders are a breeze to tell apart, all you have to do is catch them, turn them over, and using a magnifying glass, compare their reproductive parts to a handy chart that YOU WILL NEVER USE IN THIS LIFETIME – STOP KIDDING YOURSELF.
All three of these spiders look the same to the naked eye, except that a full grown Giant House Spider can be 20 to 25% bigger in the body with much longer legs. When it is fully grown. Otherwise it presents exactly like the rest of them. Go ahead and wait to see if it gets bigger. No, really we can be patient if you can…
House spiders are awesome if you like superfast icky crawling things racing around your home, especially at night, attacking and eating each other. Even during mating season there is a good chance of being on the menu. There has to be another joke in there somewhere.
Anyway, the Giant House Spider is in the Guinness Book Of World Records for being the fastest true spider. Remember that when you try to catch them to let them go in the wild. Just remember to take them far far away, or they will just chuckle as they make their way back inside your home from your yard—I mean, they got into your house in the first place, right?
It is important to know that none of these spiders are poisonous. Yes, although the Hobo Spider gets a bad rap, and there are plenty of people writing articles about it, it’s just not true. Their reputation for being poisonous comes mainly from a common misdiagnosis from doctors and from folk lore.
The Brown Recluse Spider does not live in our area. Exhaustive studies involving many tens of thousands of spiders have proven this. They cannot survive here. In 30 years of killing millions of spiders, I have never seen one or had one presented to me by a customer. however, it is common for doctors to look at a patient where bacteria has caused an open, weeping wound and diagnose it as a Brown Recluse Spider bite.
There are dozens of causes for these types of wounds that do not involve spiders.
A percentage of Hobo Spiders in those same exhaustive studies did test positive for traces of a bacteria that can cause tissue necrosis, open weeping wounds. It is possible that other types of spiders may also carry this or other similar bacteria, but venom from the spiders did not cause open wounds and wasn’t particularly toxic to humans.
Also, this is the time of year when spiders spin webs all over the darn place – from your eaves and gutters - across every single square inch of your property that you want to walk—sometimes multiple times as day. It’s too early to tell if we’re going to have the out of control spider season like we did last year.
Last year the population was so high that we could barely keep up, so I hope so :).
