Sowbug Identification

There are a variety of different insect pests you may find in your home on an infrequent basis. Unlike typical infestations of roaches, ants, or spiders, these occasional invaders aren’t usually considered problematic enough to be covered by most pest control agencies. But at Hitmen, we understand that just because these pests aren’t dangerous doesn’t mean you want them hanging around. Our year-round pest control program covers common pests in San Francisco, offering year-round protection for your home or property.

What Are Sowbugs?

Most of what we’d classify as “occasional invader” pests are insects that usually spend most of their time outdoors, but have ventured into your home or business for some reason. It could be because the San Francisco environment is too hot, cold, wet, or dry for their liking. Maybe they’re looking for a food source. Or maybe they’re just attracted to the light. And even if a large number of boxelder bugs or stink bugs find their way in, for the most part, occasional invaders still prefer to build their nests outdoors. Those that do make it indoors won’t survive more than a few days before dying of water loss.

What Can I Do?

Instead of maintaining a consistent presence, most of these pests will come and go due to inadequate food or moisture indoors. However, if you can’t wait that long, there are a few things you can do to mitigate the issue. Because many of these insects prefer dark, moist environments, you’ll typically find them in unfinished basements or crawlspaces. Placing glue traps in these areas is a safe, effective method of home pest control, but can’t guarantee 100 percent removal of insects. You could also try store-bought pesticide sprays, but they can be hazardous to your family or household pets even if applied properly
