Why Are Tiny Black Bugs Appearing on My Windowsill?
Understanding the reasons behind the presence of these bugs can help prevent them from returning. Common causes include:

Bugs like ants and weevils are attracted to food ptopics, especially sugar, flour, and grains. Keeping windowsills clean helps reduce infestations.

Potted plants near windows can harbor pests, especially fungus gnats and other moisture-loving insects.
4. Cracks and Entry Points
Tiny gaps in windows and doors allow bugs to enter from outside, especially during seasonal changes.
5. Lights and Warmth
Many insects are attracted to artificial light and warmth from windows, particularly in the evenings.
