Homemade Flea Trap

This trap uses:

disposable container, like a baking pan
water
vinegar
nightlight

Fill the pan half full with water. Add about 1/4 to 1/3 cup of vinegar and mix with water. Find a convenient outlet and plug in the night light. Place pan of vinegar and water under nightlight. The fleas are attracted to body heat. The nightlight will draw them and when they try and reach the heat they will fall into the pan and die. The vinegar works like an insecticide.
