Pillbug Infestations

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 New Mexico Pest Control , 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 New Mexico, offering year-round protection for your home or property.

What Are They?

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 New Mexico 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 pillbugs 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 If I Have Pillbugs?

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.
