What this product is best at
What problem it solves
Biogents BG-Mosquitaire CO2 Trap is a continuous trapping tool for a yard where mosquito pressure persists over time. Placement and uninterrupted operation matter more than using it for one evening.
It does not provide immediate personal protection and should not replace source reduction or a repellent when bites are happening now.
Who should buy it and who should skip it
