Think? They are gnats. They are in my house every morning all over the kitchen, bathroom & windows. I notice them at night on the outside windows, 100's swarming, totally covering the window outside. Size is about an eight of an inch. Do you know what they are and how to keep them away? Thank you, Patti

Whiteflies can be an issue with indoor plants.
Fruit flies can also be an issue in homes.
I can't identify your issue with just the description, it may require pest control experts to help you.
