I found these little tiny almost mircoscopic bugs in every window seal, even in the upstairs windows. Raid seemed to have killed them but is anyone aware of what they are?

It's pretty hard to answer your question without further details. Can you post a photo of 'em? What part of the world do you live in? Do they fly? Do they hop? Have you recently bought flowers or plants that you've put in the area that you see them? Do they head for the sunny windows? Are they anywhere else in the house? Do your neighbors see them in their homes? Have you seen any outside?

As you can see... and because there are so many species of tiny bugs... we need to narrow the possibilities.

In the 2 houses I've owned, they've been in both of them. (southern states) They're so small they come right through the screens. Just deal with them till they're gone. Do what you've been doing.
