Pioneer Backpack Rechargeable ULV Fogger - Portable Disinfectant Sprayer for Pest Control, Sanitization & Mosquito Repellent | Ideal for Farms, Warehouses & Outdoor Use

I use this machine regularly during mosquito season. It took a little time to get it primed, but once primed it functioned very well. the only reason gave 4 stars instead of 5 stars is that it tends to self siphon if the nozzle is not properly stowed when not being used.
