Every morning I have these itty bitty flying bugs in my bathroom window seals.

Asked March 18, 2019, 8:41 AM EDT

We put plastic up and it seemed to get rid of them for about a week. But they are back now every morning with about a hundred. I vacuum them up daily or just grab paper towels and kill them. They don't run fast just fly periodically. Please help they are very tiny and black.

That fly appears to be a fungus gnat. I would need to examine some to be sure. Please send me 3-4.

Fungus typically develop in the soil of potted plants.

To preserve and protect fragile specimens, it’s always best to submit insects in a small leak proof vial filled with rubbing alcohol or vinegar (the postal service prefers you send them in vinegar). Place the vial in a small zip-lock baggie, then in a small box or mailing tube and mail to
