Nothing kills bugs like Flowtron. It have been like July 4th in my backyard since the day I installed Flowtron. I moved into a newly developed area with forest and creeks around. Mosquitoes are everywhere. When I open my door at night, they swamped into my house and it's scary. 2 days after the installation, I can open my door and only one or two would fly in. then,  in house zapper took place and killed them all. I have recommend this to all the neighbors and soon, this block will be a mosquito-free section of the neighborhood.
