Recent Customer Questions

I had a mosquito trap, those zappers that said it's all weather, however, we had a few days of heavy rain and it stopped working. Can I leave the Skeeter Defeater outside in the rain? Also, I do have dogs, they live inside but are outside in the yard playing all the time. How soon after the yard has been sprayed can they go out and play? I read that the Skeeter Defeater kills insects for 3 hours after a spray, so would that mean we can't use the yard for that time frame. Thank you.

What is the effect of Pyrethrin on birds or bats that may eat the dead mosquitos?

I am very interested in this product. I understand it sprays at dawn/dusk and via remote but I would like to know how long it works after each spray. Thank you! –Gary
