A recent AARP magazine recommended killing bed-bugs by putting pillows, etc.(not meant to be washed in hot water) into sealed plastic bags and into a closed car sitting in the sun. I'm wondering if anyone has tried this for fleas. (yes, the vet found them on our cats this visit) I would think this would produce extreme heat as well as very lower humidity.
Fleas don't do well in heat. In coastal Southern California, fleas are almost impossible to get rid of. In the inland deserts, you can't find them. That's the big difference humidity can make. So yes, you can cook fleas out of stuff (but I wouldn't put the cat in a plastic bag in the car). Hey, if you are looking for a reason to visit Las Vegas, take the cat with you and by the time the trip is over the fleas will be too.
