About Mosquito Squad: Mosquito Squad founded the Protective Barrier Spray in 2005 to help outdoor lighting installers fight the bite while working. Yes, we are the original mosquito control business, and yes, we have protected more than 100,000 backyards. And true, we have received thousands of thank you notes and rave reviews from our clients for allowing them to use their backyards freely again without having to worry as much about mosquito bites.
