Boosts your trap’s attractiveness for all mosquito species:
House mosquitoes
House mosquitoes lay up to 350 eggs in rain barrels, abandoned watering cans and buckets, garden ponds or puddles. They set out in search of blood meals especially from dusk till dawn and are particularly troublesome then.
Floodwater mosquitoes
Floodwater mosquitoes usually occur in very large swarms and can be active day and night. They lay their eggs in regions that are flooded. After floods, masses of larvae can hatch almost simultaneously.
Tiger mosquitoes
Unlike most other mosquitoes, tiger mosquitoes are day biters. They are small, black and white striped as well as unusually aggressive. Female tiger mosquitoes normally lay their eggs in natural or artificial containers filled with water (e.g., water residues in flower vases), no matter how small they are, making the Asian tiger mosquito perfectly adapted to the urban environment.
Catch them all!
CO2 boosts your trap’s catch rates for all mosquito species for maximum catch rates
The combination of the BG-Sweetscent and CO2 increases the catch rates of tiger mosquitoes even further
Missing Order & Unanswered Email
I placed my order in March, and as of today, May 4, 2025, I still have not received it. The package does not even appear to have left Germany yet. I have contacted the company multiple times but have only received a single response. Meanwhile, the company continues to send requests for me to review the items that have supposedly been shipped and when I give a bad review they ask me to email them! This demonstrates a high level of disorganization within the company.

VerifiedGood service, but expensive product
I have always had great service from Biogents and this order was no different. The New Regulator is a big improvement on earlier ones, but it was very expensive for what it is

VerifiedNever delivered—just took the money!!!
I've been waiting for three weeks (order placed on June 27, 2025) for the delivery I paid for three weeks ago (July 1, 2025)! The store has been unreachable by phone for weeks. I haven't received a reply to my numerous emails. I'm absolutely furious!!!

VerifiedWE HAVEN'T USED THE TRAP WITH THE CO2 BOTTLE YET (we're saving that for when our grandchildren visit at the end of this month), BUT WE'RE ALREADY SATISFIED WITH THE TRAP USED WITH JUST THE SMALL SACHET.

VerifiedCO2 Kit
Proven effectiveness: before, with just the basic system, 5/6 mosquitoes per day; now with CO2, 15/20 mosquitoes per day, and I can water my garden without getting dozens of bites. I gave it 4 because, yes, it works, but it’s still quite an investment.

VerifiedMosquito control
I've been using Biogents products for 2 years now, and I can say that mosquito control is effective. Of course, there are still a few left, but we can eat on the patio; it's very bearable.

CATCH THEM ALL WITH CO2
CO2 (Carbon Dioxide) is a component of our breath and helps mosquitoes find us in their search for a blood meal from a relatively long distance. Using CO2 as an additional attractant makes our mosquito trap BG-Mosquitaire irresistible for all mosquito species.
The two attractants BG-Sweetscent and CO2 mutually enhance the trapping effect. With the BG-Booster CO2 upgrade set, CO2 is optimally dispersed and the release rate can be adjusted to the local and seasonal mosquito situation.
