liked it because it has a fresh smell of mint and lemon, it has no strong chemicals that harm health, I put it in the kitchen and in the places where these animals are most likely to exist and I did notice fewer signs of mice and spiders after several days. Easy to use and gives me peace of mind that it is safe for pets and family.

I used them to repel fruit flies and they seemed to help, but they do have an extremely strong smell.

They actually work!

I’ll admit I was a bit skeptical about this product but it really does seem to work. We have a nice front porch in NE CT and a lot of times the mosquitos are just too annoying to be able to sit outside. I’ve had 3 of these balls in one of the provided bags for a few days and have hardly seen any mosquitos! The smell is a strong citronella but not unpleasant.

Florida mosquitos

These have a good smell and seem to keep the Florida mosquitos away really well. I'll use 2 or 3 for my outdoor area and space them apart.
