Amazon's solicitation of feedback is premature. The manufacturer mentions 30 days for results.That means the four stars should be taken with a grain of salt.They light up ... I can't hear a thing.But the old cantaloupe in the garbage does not have surface residents! No roaches. No flies.The only potential problem for success is that they require unobstructed openness.Where in America are electrical outlets located in apartments near the floor without furniture or other items near them? Unrealistic expectations. One is lucky if apartments are wired for a refrigerator. :) :)Otherwise things are going well ...

I dislike any unwanted guest in my apartment. Like anyone else, I try to avoid little critters as much as possible. This product has been amazing. I can honestly say the only area of the house like my staircase to go up to my apartment-- that does not have an outlet, is the only are that I've actually seen a bug- spider! We had to replace the plugs after a year, since a critter or two try to sneak in, but when I tell you, Nothing!

No more bugs

These draw in ants from your yard, I installed several of these in the electrical outlets all the ants started coming into the outlets. It was crazy I threw them all away. Made in China ?

It takes longer than 30 days to see results. I guess it's ok!!!

I followed the directions exactly and placed the devices in each room to create a perimeter to block out the ants. Sure enough within about 7-10 days my ant issue was solved. So happy I bought this product. Please, use as directed and let the time pass. It does not work within 1-2 days. It needs at least a week.

I did not think that this item would work but it did. I’m very pleased with this item & purchase.

Works great. Haven't seen any bugs lately
