Thank you. That may have to be the case as the light switches don't have an easy bandaid like the baby proof plugs. I'll look into the putty.

That's super helpful, thanks. Yeah if it was just one I would consider going in the wall to get around outside the box but it's a bunch of outlets on various wall sections. So the fire putty is safe inside the box? Won't cause overheating or doesn't need air circulation?

Ah those kits still just seal around the socket, where my issue is air coming through the socket itself. Looks like I'll have to stick with baby proof style socket plugs.

Thanks I'm going to look into those kits.

Thanks! but what about the leaking air through the socket itself (coming from the hole for the wires in the back of the box)

Electrical outlets on every exterior wall are leaking air, mostly through the grounding plugs. Smart me thought to caulk up inside the box where the wires come through. Now I'm reading that's a bad idea. Sealing around the box, no problem, inside the box.. problem?

1. How important is it to remove all the caulk I just dumped in there?
2. What are good options for sealing the outlets? I've heard of the child proof plastic plugs, but that's such a bandaid.
