I read somewhere on one of my many forums that, if you plug in a night light and put a dish of soapy water under it, fleas will jump toward the light, fall into the water, and drown. The soap is apparently supposed to keep them from escaping somehow(?).
Well. Yesterday morning I sat down in my teeny-tiny hall bathroom and immediately had three fleas jump on my foot. This is, of course, NOT OK! So I decided last night I'd try my little experiment.
I had to rig up the night light because there are no outlets close to the floor in the bathroom, but I took a household extension cord (one of those short white ones), plugged it in to the outlet above the counter, ran it up through a towel bar, and then let it hang close to the floor. Plugged the night light into it, put a dish under it (about three inches deep, full of water with lots of soap), and closed the door.
This morning I went in and there were six fleas in the water! Voila! It worked! Too cool! Most of them were teeny-tiny, but there were a couple of big ones in there.
Nine fleas, just in my teeny-tiny bathroom. Wonder how many there are in the rest of the house? I shudder to think...
