I found a flea as I was furminating my cat earlier. I treated her and the dog with Advantage, trapped all of their bedding in the washer ready for tomorrow morning's wash, vacuumed the whole house, and then sat down and watched some videos. The videos (see YouTube) were of people who had used the method of trapping fleas in a bowl/plate of warm water with plenty of added dish soap, then a desk lamp is shone continuously on the dish in an otherwise dark room. Well, I don't have a desk lamp so I placed it by the halogen heater near where I sit and kept my eye on it very carefully for safety's sake. My cat has been chilling next to the bowl for a while, and the dog just showed up briefly (he doesn't have fleas). I wish I had a desk lamp to leave on all night... When I go to bed in a minute, I will turn off the heater and remove the water but, glad to say, I haven't had any fleas jump in over the last two hours. The dots on the bowl are just stars! Just thought I'd share this in case anyone else wanted to try it who has a desk lamp.
