I wasn't sure which way to turn on getting rid of mosquitos. I ended up biting the bullet and purchasing this fogger because nothing else worked. This things nocks their numbers down significantly but it works at it's best when the is no wind at all! I had to use it regularly for 2 weeks, every 3rd day or so. If you have no wind about and fog the place it will actually destroy Mosquitos..! Surprisingly it works quite well.
