  • Cracks and holes in walls: if there's an opening, bugs will try to find their way into your house.
  • Gaps around entryways: bugs usually find their way into the bathroom or kitchen because entry points aren't sealed properly.
  • Messy house: a cluttered home and window sills left to gather dust and debris are ideal for bugs
  • Other insects: the presence of other small bugs in the kitchen or around your home can attract the ones near your windows. Carpenter ants, cockroaches, fruit flies or gnats, houseflies, termites, and other pests are food sources too.

Prevention and Control

Tiny black bugs in house near window are a nuisance. Different species that come from outside your house (e.g., the garden or lawn) can infest your personal space and encourage other bugs to do the same. To prevent these tiny bugs from getting into your home:

  • Keep your windows shut: close your windows, especially during the summer when these bug populations reproduce like crazy and are the most active.
  • Keep your window sills clean: making sure that the window sill is squeaky clean reduced the chances that bugs will be attracted to them. This also gets rid of any potential food sources.
  • Remove moisture sources: bugs are drawn to standing water and other sources. Learn how to repair that leaking kitchen faucet and pay attention to areas with high humidity around your house.
  • Keep an eye out for other insects: if you see a single gnat, fly, bed bug, housefly, or a whole ant colony, this can indicate that you'll have a different type of bug species infestation at hand.
  • Properly store food away: by keeping food properly sealed, these small bugs don't have a potential food source or breeding ground.
  • Smell your home: if there's a musty odor, it can indicate mold, mildew, or bugs.
  • Pest control: one of the best ways to prevent an infestation is by reaching out to a professional pest control specialist for a customized plan and regular inspection.

  • Bay leaves: certain plants like bay leaves act as a natural pest repellent! Place them near windowsills during the winter, spring, summer, or fall.
  • Sticky traps: you can buy sticky traps to catch bug bodies and physically remove them from a certain area. You can also buy fly traps or light traps.
