Hello Christi, I bought myself an ultrasonic pest repeller few weeks ago. My mom found out about great devices from Crioxen. Their products are made from ecological and high-quality materials, so you can buy pest repeller
. These devices don't contain harmful chemicals. so each model is safe for humans and pets. Firstly, I was wary of its work, but the device totally approved itself. And the balance of price and quality is totally satisfying. My repeller has a large coverage zone and it's portable so I can set it anywhere at home and it's easy to look after. Some types can resist not only from mosquitoes but rats and bats! I highly recommend you to look up there!
