Pros
- Built for the day-biting Aedes that bite indoors, using visual contrast, a warm plume, and scent rather than light (about 40–75% fewer bites in testing)
- Chemical-free and far more selective than a bug zapper or light trap
Cons
- Thins a room's mosquitoes over days rather than protecting you on the spot
- Needs the scent lure replaced and the trap running continuously
- Frequently out of stock and sold mainly direct, so it can be hard to buy
The full review
An indoor mosquito trap from Biogents, the German maker whose traps are used in vector surveillance worldwide, and the rare consumer trap actually built for the day-biting tiger and yellow-fever mosquitoes (Aedes) that hunt you inside. Instead of light or carbon dioxide, it imitates a person: visual contrast, a warm human-like convection air plume, and a skin-scent lure, which is the exact combination host-seeking Aedes follow. A quiet fan draws them in and holds them, with no insecticide and no electrified grid. In the maker's testing it cut Aedes bites substantially. The honest caveat is that a single unit thins the mosquitoes in a room over days rather than out-competing you as a living host on the spot, so it belongs alongside source reduction and a skin repellent rather than replacing them. One practical problem: it is frequently out of stock, sold mainly through the Biogents shop, so it can be genuinely hard to get hold of.
Scorecard

Effectiveness45%55This is an indoor trap, not applied to skin: it imitates a person with visual contrast, a warm convection plume, and a skin-scent lure (no CO2 and no light) and captures the day-biting Aedes drawn to it, cutting bites by roughly 40–75% in the maker's testing. A single unit thins a room's mosquitoes over days rather than out-competing a living person on the spot, and results depend on where it is placed and on keeping the lure fresh. Scored on that realistic room-level effect (lower confidence).

Safety15%75This is a standalone trap, not applied to skin, so there is no dermal exposure and no pesticide vapor or smoke to breathe. Because it lures mosquitoes with CO2, heat, and scent rather than zapping everything nearby, it is far more selective than a bug zapper and does not kill large numbers of harmless or beneficial insects. Place it away from where people gather so it draws mosquitoes toward the trap, not toward you.

Coverage & effectiveness
This is a trap: it lures host-seeking mosquitoes with CO2, heat, and scent and captures them, thinning the local biting population over time. It works slowly across a yard rather than protecting you on the spot, and results depend heavily on placement and running it continuously.

This is the best-evidenced consumer trap for the day-biting Aedes that bite indoors, and unlike a light trap it targets the cues those mosquitoes actually follow: visual contrast, a warm convection plume, and a skin-scent lure rather than light or CO2. Biogents testing reported up to about 87 percent fewer Aedes bites, which is genuinely encouraging, but that is a best case. A single unit thins the mosquitoes in a room over days rather than out-competing a living person on the spot, and results depend on placement and keeping the lure fresh, so we score it on that realistic population effect and pair it with source reduction.

Claims audit
What the marketing says, versus what the evidence supports.
“Reduces Aedes mosquito bites by up to 87% in testing”
EfficacyModerateA manufacturer testing figure and a best case; a single indoor unit thins a room's mosquitoes over time rather than out-competing you as a host.
“Traps day-biting tiger and yellow-fever mosquitoes indoors without CO2 or a zapping grid”
EfficacyModerateIts design imitates a human with visual contrast, a warm convection plume, and a skin-scent lure, which is what host-seeking Aedes actually follow, and it is well supported for Aedes specifically.
“Chemical-free and quiet, no insecticide”
NaturalStrongAccurate: it captures mosquitoes with a fan and lure, with no pesticide and no electrified grid, so it is far more selective than a bug zapper.
