Unfortunately, cockroaches are not loners. If you see one, there are likely many more that you can't see. If you do see them during the day, it's usually because roach overcrowding has forced them out into the open, so chances are you've got a pretty large roach infestation.
Should I worry if I find one cockroach in my house?
Yes, you should be worried if you see one roach in your home. Roaches are solitary bugs. So, if there's one in your home, then the chances are relatively high that there are many of them hiding and breeding inside your home. To remove your worry, you need to be proactive and look for the roaches in their hiding places.
Can you just have one cockroach?
Absolutely! Roaches rarely hang out alone, so a single cockroach is almost always a sign of a larger infestation. This is especially true if you spot one during the day, as cockroaches are nocturnal creatures and will only venture out during daylight if they are being crowded out of their usual hiding places.
Does 1 roach mean infestation?
While the presence of one cockroach in your home can be enough to send you into a panic, one roach doesn't necessarily mean you have a full blown infestation. Cockroaches are dangerous to humans they carry bacteria on their bodies and their feet, contaminating any surfaces they come into contact with.
