Does that creepy-crawly have lots of friends lurking in your home, or is it a loner?
It goes without saying that seeing any cockroach in your home is not exactly an ideal situation. But there’s a big difference, in terms of grossness factor, between that cockroach being a loner or that cockroach being one of the hundreds infesting your home. But if you only see the one roach, how are you supposed to know?
Just approximate the size of the bug—if it’s longer than an inch, it’s probably “an outside cockroach that found its way in.” If it’s shorter, it’s probably living in your house with lots of friends, and it might be time to call the exterminator. Of course, no one is suggesting that you grab a ruler and measure the length of a creepy-crawly in your kitchen, but eyeballing it should be enough to estimate whether or not it’s longer than an inch.
Keep in mind this tip isn’t the end-all, be-all; just because a roach is bigger than an inch doesn’t automatically mean it’s a one-and-done situation. However, it is true that the type of cockroaches that is most frequently responsible for home infestations in North America is usually smaller than an inch. These bugs, called German cockroaches, can breed rapidly and average about 0.6 inches in length. Another common culprit of home infestations is the brown-banded cockroach, which is even smaller and prefers dry spots, like walls and ceilings.
As for the big bugs, they’re less common inside homes, but if you see one, you’ll know. American cockroaches, also known as “Palmetto bugs,” can be as big as three inches and do infest homes sometimes (especially in warmer climates), but they “prefer outdoors.” Another type of larger roach, smoky brown cockroaches prefer damper environments, but are attracted to light and will enter homes when they see it.”
If you prefer being safe than sorry when it comes to pest control, you might want to call in the experts no matter how big the bug, especially since all types can carry harmful bacteria. But if you see a roach that’s on the smaller side, it’s definitely more likely that it’s one of many.
