If you’re wondering whether or not you have no-see-ums, there are a few signs to look for. First, check for small, red bumps on your skin. These are typically a sign of an insect bite. If you have bites in a line or cluster, it’s likely that they’re from no-see-ums.

Another sign of no-see-ums is finding them in your home. These tiny insects can sneak into your house through cracks and crevices. If you find them in your bedding or on your walls, it’s a good indication that you have an infestation.

Finally, listen for a high-pitched buzzing sound. This is the sound that no-see-ums make when they’re flying around. If you hear this sound in your home, it’s a good indication that you have an infestation.
