its flea season

Wash all bedding (kitty and human well and often in hot water) and leave a very long time in the dryer....steam kills the little nasties. I do recommend switching to light-colored bed sheets, as inspections are just easier that way.

Eggs and larvae like to hide in cracks and crevices of furniture & on blankies...vacuum often, and you can put pyrethrin flea powder (not too much!) in your vac bag to help prevent re-infestation (take all used vac bags outside, sealed with tape & tightly wrapped).

I've used pyrethrin products without any ill effects, and I have a touch of asthma and allergies to many things. Use sparingly and you'll be amazed at its effectiveness.

I don't believe in flea collars anymore as one old boy went stark raving mad wearing one, and totally went off his food and became quite ill, as well. Took it off him and he was immediately much better. Being consistent with inspections and killing the nasties by hand works pretty well. Just wash hands thoroughly and stay on top of the situation.

Maintaining a flea-unfriendly environment is easy once you get used to it. I had a lot of success doing these things, with both my rescue kitties.

Hugs, y'all.
