For many, the onset of fall is the best time of the year. The leaves change into crisp, golden colors and spread themselves along the ground. Football games, bonfires, pumpkin spice-flavored anything, it’s all here. As we adapt and change with the seasons, however, so do our arachnid friends. Spiders change their habits just as any species does when summer turns to fall, and some of those habits aren’t thought of too fondly by humans. Let’s take a look at what spiders are up to when autumn arrives.
While not the true mating season for all arachnids, the San Diego area has a couple of types of spiders that seek to lay their eggs during the fall. This includes orb weaver spiders, California Ebony Tarantulas and San Diego Bronze Tarantulas as well as house spiders. Male spiders will emerge from their burrows looking for a mating partner. For the tarantula species, the females will actually sometimes attempt to eat the male spider after mating, forcing the males to flee quickly. The orb weaver females typically die within months of laying eggs, so they are alone till hatching in the spring. If there are more spiders around your home in the autumn months, it’s probably because they are looking for a mate.
It’s Not the Cold
Most people think their homes are invaded by spiders because the temperature is dipping outside. This is a common misconception. Spiders are cold-blooded creatures, therefore getting to a warmer spot indoors is not a priority for them. Again, they are simply looking to partake in mating season, which is where you will see the influx of arachnids in your home. Fortunately, there are ways to limit the invasion.
