Why it works
CO₂ is the primary cue blood-seeking females use to locate hosts. Adding CO₂ to the BG-Mosquitaire can multiply tiger mosquito captures by 10× compared to attractant-only traps.
Unlike heat-and-scent-only traps, CO₂ attraction works across all mosquito species, including Culex (common house mosquito) and Aedes (tiger and yellow fever mosquitoes).
Fully waterproof, UV-stabilized housing rated for permanent outdoor installation. Built to handle Austin summers, Hill Country rain, and years of continuous operation.
Ships with a pressure-reducing regulator, CO₂ delivery nozzle, and 16-foot CO₂ tube. Everything you need to connect to a standard CGA-320 tank — no extra purchases required.
Biogents' patented 3-component blend mimics human skin scent. Works synergistically with CO₂ to further increase catch rates. Each pack lasts up to 2 months.
5W fan and power system run quietly 24 hours a day. Positioned correctly downwind of seating areas, you will not see it or hear it — only notice fewer mosquitoes.
What's included
Technical details
Frequently asked
Does this include everything I need to start? +
Almost everything. The trap ships with the regulator, CO₂ nozzle, tube, bait, and power supply. The only thing you need to add is a CO₂ tank (sold separately) and a local CO₂ fill. Our monthly delivery service handles the CO₂ for you starting at $89.99/month.
How long before I see results? +
Most customers notice meaningfully fewer mosquitoes within 1–2 weeks. Peak population reduction typically occurs at 6–8 weeks as the compounding effect of removing breeding females takes hold.
Where should I place it? +
Downwind of your primary outdoor seating, near shaded vegetation, and away from competing CO₂ sources. Every equipment purchase includes a free GreenGuard USA placement consultation — we confirm your placement before your first tank runs.
What size CO₂ tank do you recommend? +
A 20 lb tank is the standard. Running continuously it lasts approximately 20 days. Paired with a CO₂ timer set to 8 hours/day, the same tank lasts up to 60 days. We carry 20 lb tanks and offer monthly tank exchange service.
Is it loud? +
No. The 5W fan produces a very low hum, less than ambient outdoor noise. Customers regularly place it within a few feet of seating without noticing sound.
