Why it works
Meets all US DOT transportation regulations. Lightweight aluminum construction with a standard CGA-320 valve — compatible with all Biogents regulators and virtually any third-party CO₂ regulator.
Fill at any welding supply store, fire extinguisher service, homebrew shop, or paintball supplier. A typical fill costs $20–$35. No specialized equipment needed.
Running a BG-Mosquitaire continuously, a 20 lb tank lasts approximately 20 days. Paired with the Biogents CO₂ Timer on an 8-hour schedule, the same fill extends to up to 60 days.
Skip refill trips entirely. GreenGuard USA's CO₂ delivery service exchanges your empty tank for a full one at your door. Starting at $89.99/month. Our technician also inspects your trap on every visit.
