Little black bugs in the house can be many different insects, including gnats. Photo: If the tiny black bugs have wings, they’re probably gnats. Regular cleaning and maintenance are key to making sure drain flies don’t become an issue inside the home. If a homeowner or renter finds these common small brown bugs in the house, it may be a sign that there is a slow or clogged drain, especially if the resident spots them in the kitchen or in a bathroom. If their population in a home becomes too big, drain flies may congregate near windows, according to The Ohio State University. Although drain flies have a lifespan of only a few weeks, new adults can replace them quickly. These bugs feed on dying organic material, which is why they can be found near drains, decaying logs, or compost piles. They have a fuzzy appearance and measure about 1½ to 5 millimeters long. But when the adult population reaches a certain size, individuals tend to congregate near windows.ĭrain flies are often light gray or tan with light-colored wings, but may look like tiny black bugs. The bait will be brought back to the colony, targeting the thousands of ants homeowners don’t see during an infestation.ĭrain flies, also called moth flies, typically live around areas where water accumulates-like the drain, as their name suggests. The worker ants will create a new trail to the bait which other ants will follow.

Once the area is sealed and the trails are cleaned, residents will want to set up a liquid baiting system to first target the worker ants, then larvae and the queen ant.

Because ants leave behind an invisible trail for other ants to follow, using soap and water to clean the trail can prevent future infestations. To get rid of these small bugs in the house, homeowners or renters will want to start by looking for and sealing any points of entry, then cleaning the surrounding areas. There are different kinds of ants, including carpenter ants that target wood structures, aggressive fire ants that are red in color and can hurt humans with a venomous sting, and little black ants that are often found in large colonies nesting in lawns or cracks in cement.Īnts can easily make their way inside through the tiniest of cracks and crevices, like those found in windows, walls, or home foundations. Ants may have wandered into your home from your yard.
