Ah, you have homeless skunk fleas.
I was gonna mention the skunk ordeal.
You’ll have to have them eradicated under the house and then do indoors.
It may not seem like you’re bit but I bet you are.
Or you have flea allergy.
I’ve brought lots of foster pets here and one thing I never worried too much about was fleas. Once the pet is medicated and cleaned they go away.
Getting infested with pet fleas is kinda hard. If you do nothing and you have 43 cats and never clean, yeah it happens.
Call the pest control company. In one day it will be over.
In the meantime spray the couch and surroundings with a good flea room spray. (Adam’s is good) Hit the places you think they might be coming in. Vents, door cracks.
Oh, walk out in the yard. If your ankles are immediately covered with fleas you have a bigger problem.
ETA…flea poop can cause asthma attacks
The man st common species of flea is the cat flea, Ctenocephalides felis. Even on skunks or raccoons
