In article , snipped-for-privacy@scoobydoo.net says... :) Do electric flea traps work? I've vacuumed the carpets twice, but :) still have fleas. The vacuum is old and doesn't have a very powerful :) suction. SHould I get a steam vacuum? I want to avoid using pesticides :) and carpet powders. I would like to know if those plug in flea traps :) with glue traps attached, work. :) The adult fleas are only a percentage of the on going problem..there will be eggs, larvae and pupae to deal with. An easy flea trap can be made that will attract adults, but will not stop a infestation from happening. Plug a night light in an outlet near the floor or place a small lamp on the floor and place a pie pan with water (few drops of dish soap optional) under the light.
Treating the pets is a must..the fleas will develop where the host animal is spending time...the adults are on the animal feeding...laying eggs dropping fecal matter (dried blood). Where ever the animal is walking, laying around, eating, etc. the eggs and fecal matter will fall off. The eggs hatch and the larvae will find the fecal matter and other organic matter and feed, so these areas also need to be treated with an insect growth regulator or IGR to stop the cycle by killing the eggs and keeping the larvae from developing into adults. Most products will contain the insecticides permethrin or linalool which only hang around a short period of time and will help kill the emerging adults from the "cocoons" but the growth regulator in the products will be active a number of months, but only effect the eggs and larvae.
You can get rid of a problem by only treating the pets with Frontline or Advantage, but it takes time...if the company you hire truly has a steam cleaner you should be able to stop the infestation if all areas are hit, including under the beds and furniture cushions. But the fleas will be back in a couple of weeks.
