I've used electronic devices with fairly good results.
Well, I believe they work -- it takes a few days. I had some I bought yrs ago, that really worked, so I went on a hunt for newer models. I bought an electronic thing at Ace Hardware that said it got rid of mice & pests - but when I called the company to ask about ridding fleas, their standard response was it hadn't been tested on fleas. But I kept it anyway & I think it's working. This is their website - I got the 2000 model

I think I paid like somewhere between $26-$29 for one
I thought about getting one from this website - it's says it works on fleas.

it looks good - but I didn't want to wait for it to ship
I have also bought black & decker models - they sell those at Target (couldn't find any at walmart) These come in single, double & triple packs. I got a double pack - I think it was like $15 -- but I almost feel like one of the companies that specializes in these things is the way to go instead of B&D - but really I have no complaint with the ones I bought
They all seem to say they may or may not work for each individual & if you have a bigger space you need more of them - like potentially in every room - well I think rooms that have furniture & carpet where fleas reside when not on something breathing
I just sent this a couple of days ago to someone in a PM that had asked me about them when I posted about having pretty good luck with these electronic devices.
I figure keeping mice, etc. out of the house is a plus too. Just be careful as they can't be used around hamsters, guinea pigs, other rodent type pets.
