hi there,

you can d.i.y flea trap easily.
can refer to this http://pestcemetery.com/green-lights-work-attract-fleas/

make sure to use green filament light bulb (for heat) and not LED type
you an find this at Ace Hardware.

also, put some detergent into the water in order to reduce water surface tension, so that the fleas are drowned.

hope this can help fighting with ur nightmare

any dishwashing liquid will do
just dont put too much, 1 spoon per 250ml of water will do.
