A company fills it with natural based mosquito repellant- they don't tell me what it is. but based on website (under FAQ) its pyrethrum insecticide. When I moved I figured it was a scam but it works. I got off their auto refill every 3 months for $150 and have dialed the pump back so a tank lasts me a season for $150. here in Jacksonville i use these guys https://www.callthegman.com/What do u put in it?
