I’ve had ants crawl into my ear at night. You can hear them scratching on the rear drum. Fortunately they’re easily flushed out with an ear syringe.
Years ago I read of a woman who had ear discomfort. Her doctor found a spider had nested in her ear.
When my house flooded, all the wall board - up three feet up from the floor - had to be replaced because it got wet.
We have a great contractor but the subcontractors were led by Americans and employed illegals even though I said I wanted no illegals working on the site.
Every night I would go to the house and clean up the floors (traverteen(sp) tile) because I did not want the subcontractors to ruin the tile and they never cleaned up after themselves. One evening I arrive and find one of them had dumped their lunch trash in the wall area. I found three lunches stuffed in the walls of the house. I made the contractor check all the walls before they put up the wall board to make sure it was clear. HE FOUND MORE LUNCHES IN THE WALLS!
That is probably why she had roaches in her new house.
