The following is a tabulation of some prior art that presently appears relevant:
Biting insect, such as mosquitoes and flies, can create health problem because they are vectors for transmitting diseases such as Zika, Dengue, Malaria, Yellow fever and West Nile Virus to mention some. Worldwide, mosquito borne diseases kills more people than any other single factor. In the United States, mosquitos spread several types of encephalitis, and lately the Zika virus is starting to spread in warm places such as Florida, Texas and California. They also transmit heart worms to cats and dogs.
Mosquitos are attracted to a host by the carbon dioxide (CO2) produced during normal breathing, Moisture from sweat, heat from warm bodies, scent, and sight. From 100 feet away (30 meters) mosquitos are able to smell a blood host's scent, especially the CO2 the host normally exhales.
Previously people have tried a number of different methods to eliminate mosquitoes and other biting insects. One method that is often utilized is spraying or applying chemical insecticides. Although many chemicals work well to kill or repel mosquitoes, the chemicals often have a negative effect on the environment, including, but not limited to, killing beneficial insects such as bees. In addition, chemical insecticides are effective only for a limited amount of time, and thus must be continuously sprayed. Moreover, many types of mosquitoes and biting insects are capable of developing resistance to chemical pesticides in a few generations (which may be only a few months for mosquitos), and in the long run, that adaptation makes the species stronger.
Citronella candles and smoking coils are often used to repel mosquitos and other insects. However, research has shown that, in general, an individual must stand within the smoky plume of the citronella to be protected. This, of course, is not desirable. Moreover, even when standing in the plume, citronella is only partially effective in reducing the probability of a mosquito bite. Encouraging natural predation of insects by setting up bird or bat houses in one's backyard has also been unsuccessful in reducing local mosquito populations. Mosquitoes are very small weighting 2.5 milligrams and do not provide sufficient nutrition to predators.
Recently, significant research and effort have been expended to develop devices that attract and trap or kill mosquitos. In general, these devices attempt to replicate the mosquito-attracting attributes of a typical blood host, such as a rabbit or a bird. The devices may include, for example, a source of carbon dioxide, a source of octenol (an alcohol that is given off by mammalian blood hosts), and/or a heat source.
One such device is sold under the trademark “MOSQUITO MAGNET” and is described in U.S. Pat. No. 6,145,243 to Wigton et al. The MOSQUITO MAGNET apparatus is an insect trapping device that generates its own insect attractants of carbon dioxide (CO2), heat, and water vapor through catalytic conversion of a hydrocarbon fuel in a combustion chamber. The hot insect attractants generated in the combustion chamber are diluted and cooled to a temperature above ambient temperature and below about 115 degrees Fahrenheit (F) by mixing with air, and the mixture is exhausted downward through an exhaust tube. A counter flow of outside air is drawn into the trap though a suction tube that concentrically surrounds the exhaust tube. Biting insects are sucked into the suction tube and are captured in a porous, disposable bag connected to the other end of the suction tube. Additional chemical attractants may be used with the device to make the trap even more effective.
Although the MOSQUITO MAGNET device works well for its intended purpose, due to the high suggested retail price, especially for its cordless models, it is far out of reach of the ordinary consumer. Thus, few people would actually purchase the MOSQUITO MAGNET, even if they have a pressing need for mosquito control.
Another example of an apparatus for attracting and destroying insects is disclosed in U.S. Pat. No. 6,055,766, and is sold under the trademark DRAGONFLY. The DRAGONFLY apparatus generally includes a source of carbon dioxide, a source of octenol, a device for emitting the carbon dioxide proximate the source of octenol to create a mixture of the carbon dioxide and octenol, a heating element, and an electrified grid. Insects are initially attracted to the apparatus by the odor associated with the mixture of carbon dioxide and octenol. As the insects fly closer to the apparatus, they are further attracted to the visual properties of the apparatus and then, at close range, they are attracted to the heat emitted by the heating element. In an attempt to fly closer to the heating element, the insects are intercepted by the electrified grid and destroyed.
Although the DRAGONFLY apparatus works well for attracting and capturing insects, because the direct current type mosquito trap electrocutes mosquitoes using direct current, it creates a dangerous situation for people, especially for children; as with the MOSQUITO MAGNET device, the DRAGONFLY apparatus has a pricing point out of the range of the ordinary consumer.
Another mosquito trap is disclosed in U.S. Pat. No. 9,049,855 and is sold under the trademark DYNATRAP, is one of the many other traps available that uses Ultraviolet (UV) light to attract mosquitoes. Unfortunately is effective at attracting light sensitive insects such as moths, fireflies, butterflies, bees and a variety of others beneficial insects that use light to either attract a mate or finding food on flowering plants. Many consumers of these traps complain that mosquitos are no eliminated or reduced in numbers. The present invention is made of fewer components and simple design that will reduce the cost of the device so it can be installed in many places and control mosquito population. This will reduce the number of people getting bitten, sick or dying from mosquito transmitted diseases.
In accordance with one embodiment a mosquito-trap comprises of a powerful fan to drag attracted flying insects into the container and trapping them, at the same time it lets air out through a screened outlet dispersing the aroma of the attractant left inside of the container to lure more mosquitos in.
Accordingly several advantages of one or more aspects are as follows: to provide a mosquito trap that is efficient at attracting and trapping mosquitos controlling their population which as a result will reduce or eliminate the spread of mosquitoes which are vectors for transmitted diseases such as Zika, Dengue, Yellow fever and West Nile virus, to name a few of different tropical diseases. The device of this invention uses very little energy and it can be used anywhere inside or outside the house. Many different attractants can be used including octanol, L-Lactic acid, Nonanal, yeast CO2 generators or a combination of all of them. Also water has an increase effect attracting mosquitoes when using in combination with any of the attractants described above.
All of the above mentioned attractants are biodegradable and they are not poisonous in any way to people or insects and do not represent a danger to people in general, this makes the mosquito-trap safe and secure to be used by anyone.
In the drawings, closely related figures have the same number but different alphabetic suffixes.
A preferred first embodiment of a mosquito-trap 100 is illustrated in
The mosquito-trap 100 operates by placing the attractant 80 inside the bucket 20 and installing the cover 30 until the snap-lock 34 attaches securely to the rim 21 of the bucket 20. Once the DC-fan 40 is powered by connecting the USB-cable 72 and USB-charger 70 to power; it creates an airflow 90 thru the inlet 31 of the cover 30 and going inside the bucket 20. The airflow 90 collects any of the Carbon dioxide (CO2), moisture or aroma produced by the attractant 80, and leaving by the outlets 32 to effectively spread the CO2, moisture or aroma outside of the trap 100. Once the mosquitoes 10 detect the CO2 and moisture aroma of the attractant 80, their senses are activated and come closer to the cover 30 where the powerful airflow from the DC-fan 40 draws them inside the bucket 20 where they hit the bottom of the bucket 20 or fall in the attractant 80 and die. The mosquitoes 10 that do not fall in the attractant 80 fly to the outlets 32 where they cannot pass and after some time they get desiccated by the leaving airflow 90 or die by starvation in a couple of hours. The attractant 80 works by spreading Carbon dioxide (CO2) in conjunction with moisture which is a powerful attractant of aedes aegypti mosquitoes which are a vector for Zika, Dengue, yellow fever and many other tropical diseases. Once the trap 100 is full of dead mosquitoes 10, the cover 30 can be removed by unlatching the snap-locks 34 from the rim 21 of the bucket 20, and the contents of dead mosquitoes 10 can be disposed in the garbage or use as fertilizer for garden plants. Certainly different attractants 80 such as Octenol, L-Lactic acid, Nonanal or a combination can be used. The attractant 80 can be in liquid, gel, solid or gas state at all times.
An alternate embodiment is shown in
The operation of the alternate embodiment of the mosquito-trap 200 starts by powering the AC-fan 120 by connecting the AC-plug 126 to an electrical outlet (not shown). The airflow 150 that the AC-fan 120 creates goes inside the container 110 collecting the aroma of the attractant 140 and escapes by the outlet 112. Once a mosquito 10 detects the leaving aroma of the attractant 140, it comes closer to the mosquito-trap 200 where the AC-fan 120 will draw it inside the container 110 where they die by hitting the inside of the container 110, by desiccation provide by the airflow 90, or by starvation in a couple of hours.
Accordingly the reader will see that, according to one embodiment of the invention, I have provided an improved mosquito trap that will help control and reduce mosquito population and eliminate disease transmitting mosquitos from a human populated area. This effective solution can be used by any person to protect themselves from mosquitoes and has many other advantages in that:
Thus the scope should be determined by the appended claims and their legal equivalents, and not by the examples given.
