A new, highly effective mosquito trap system against blood-sucking insects (gnats, blackflies, mosquitoes, horseflies, etc.). The operating principle is based on the following factors that attract mosquitoes:

- the housing is heated to a human body temperature;

- carbon dioxide (CO2) emission which imitates breath;

- discharge of attractant substance (Nonanal), having high efficacy in attracting mosquitoes, which has been proven by American entomologists Walter Leal and his colleague Zain Syed. According to their complex research, a female mosquito navigates her prey not only by the location of heat and CO2, most actively it follows the concentrations of nonanal contained in the sweat of humans and animals.  

Carbon dioxide discharge and heating of the system's housing have a periodic nature which imitates animal's movement. This attracts mosquitoes. When they approach the system, they get sucked inside by a fan and then end up in the netted container where they die.

The device is a safe alternative to utilizing chemical substances for mosquito control. It is silent and reliable and is the most effective way of terminating blood-sucking insects where potentially dangerous pesticides and other chemical methods are not desired.

Another important advantage is that the device does not attract beneficial insects which is the case with devices utilizing UV lamps. A study held by the University of Notre Dame in South Bend, Indiana showed that approximately 70-350 billion of useful insects are annually destroyed by devices with UV lamps. Additionally, UV light helps mosquitoes to find water where they lay eggs.  

Tests showed that GRAD Black G1 is capable of attracting and destryoing a large number of blood-sucking insects at evening and night time, from 200 to 10,000 insects and even more. This number greatly depends on the mosquito contamination in the area and the particular land lot.

The built-in light sensor allows the device to engage automatically at twilight when mosquitoes are especially active. And it turns off during the day thus using electricity and CO2rationally.

The device's heavy duty design makes it safe to use it openly under precipitation.

The operating principle is based on the imitatation of the main factors that attract human biting insects (mosquitoes, flies, gnats, horseflies etc.) by the device.

These include:

- device's housing is heated to body temperature of a human or warm-blooded animal;

- carbon dioxide (CO2) is discharged to imitate breath;

- attractant substance (nonanal) is discharged to imitate the smell of a human or animal.

After being sucked by the fan, the attracted mosquitoes fall into a netted container where they die.

The fan does not suck in all the mosquitoes that sit on the housing at once. Being attracted by the imitating factors to the housing, mosquitoes would fly around the device for a while but eventually would end up inside the container.

We highly recommend utilizing high refinement grade carbon dioxide gas (usually referred to as food carbon dioxide). Gas with impurities would significantly lower the effectiveness of the device. Such impurities as mineral oils, hydrogen sulphide, ammonia etc. may even scare mosquitoes away and thus decrease the effect of the device.

Important! The device utilizes SAFE carbon dioxide gas, not highly exposive propane.

Carbon dioxide is a gas that we all exhale. It is not harmful to humans and it is not flammable. On the contrary, propane gas used by other manufacturers is HIGHLY EXPLOSIVE and needs to be treated with great care.  

The best location for installing the device is an area between mosquito breeding spot (swamp, lake, lowland or timber) and the protected area. It can be mounted in bushes, over thick grass, under trees, etc.

Utilization of nonanal as an attractant allowed to significantly increase the effectiveness of mosquito attraction compared to other mosquito killing systems. There is no other device that uses this new substance - nonanal - in the Russian market. According to a very recent science research, it is the very substance, contained in the sweat of humans and animals, that tells mosquitoes that there is food for them around.

Nonanal is an alkyl aldehyde contained in human's sweat, it is a colorless and oily liquid. It «sends a message» to mosquitoes about the location where there is food for them.

Nonanal and carbon dioxide combined action multiply the number of mosquitoes that react to their effect by 1.5 times.
