they were hiding and waiting till you went to sleep. When it’s hot outdoors they come to the covered entrance and stay next to the door and some of them slip inside when you open the door to come in.

Let me make a wild guess--do you live in Alabama?

Mosquitoes outdoors can easily become mosquitoes indoors but are you sure that it was in fact mosquitoes?

You ran out of ammonia!

They smell an Alabamian haha

Welcome to my world!!
