I live in a town house, so I cannot remove my carpet. The exterminator came and sprayed my room and that helped for a bit, but I keep getting these red bumps that itch. I changed detergents and soap powder to non-fragrant sensitive brands, just in case that was the issue. No matter what I do, I still get bit. Is there anything I can take? Since it's been hot and humid it's gotten even worse, even with me having my own AC unit in my room.
