1. Bring a big plate into the area of infestation (I used a big plastic dinner plate 1 cm deep) Mix warm water and detergent and pour into plate.
2. Place plate in a safe place away from children or pets.
3. The fleas will be attracted by the warm water, jump into the mixture and drown as there is no surface tension (the detergent took care of that)
4. No one and no pets were allowed in my den when I was using this method.
5. Changed it 2-3 times a day until infestation has been reduced.
