Definitions

  • Embodiments generally relate to insect trapping apparatus.
  • Mosquitoes are the most deadly insect, killing the most human lives as compared to other living animals.
  • mosquito bites create nuisance to people and animals as well.
  • human have tried many methods to get rid of mosquitoes and biting insects in their living environment.
  • repellent or insecticide The most common method is to apply or spray chemical repellent or insecticide.
  • Some of these repellent or insecticide e.g. Scourge, Anvil, Permethrin, and Malathion
  • repellent or insecticide is often used as temporary solution and stay partially effective for a limited time only.
  • repellent or insecticide needs to be continuously sprayed in order to be effective for a prolonged duration.
  • other useful insects such as bees, may also be killed in the process.
  • the insects and mosquitoes that are exposed to the insecticide and have survived may produce offspring that may build up the resistance towards the insecticide in the long run.
  • mosquito traps Another common method to combat mosquitoes is mosquito traps. These traps are customized by having different modification to cater to indoor or outdoor usage. They mainly attract female mosquitoes which intend to suck blood so as to produce and lay eggs later. As such, attractants such as carbon dioxide gas, heat, lights, chemical lures are commonly used in traps for mosquitoes. These attractants are used to mimic human breath, body temperature, movement and sweat/smell. Currently, only outdoor mosquito trap utilizes carbon dioxide gas along with various other attractants as mentioned above. Typically, carbon dioxide gas is provided by a compressed carbon dioxide gas tank, or by conversion of fuel into carbon dioxide gas via burning or catalytic conversion from a fuel tank.
  • mosquito traps are generally known as ovitrap. Most of these mosquito traps utilizes still water only, and utilizes the chemicals naturally released by the egg and larvae that are laid successfully as lure. These chemicals will attract more female mosquitoes nearby that are also ready to lay their eggs. In some of these mosquito traps, the egg laying mosquitoes will then be entrapped by the structure of the mosquito traps or adhered to sticky pads of the mosquito traps. In some other mosquito traps, the egg laying mosquitoes are not entrapped after laying eggs.
  • mosquito traps that prevents larvae from reaching the surface to breath or with weak chemical insecticides.
  • the main flaw of such mosquito traps is the reach and coverage. As these mosquito traps function as normal breeding sites, they will only work on mosquitoes that are nearby and that choose the mosquito traps as breeding site among the rest.
  • Another method to combat mosquito is to use fungi in mosquito traps to infect the eggs, larvae, and the egg laying mosquitoes.
  • the egg laying mosquitoes are then allowed to leave the mosquito traps while infected, and continue to lay eggs at other nearby breeding sites and infect these breeding sites.
  • mosquito traps require replacement of fungi source periodically, for example every 4 to 6 weeks. Failure to do so will result in the mosquito traps becoming a normal breeding site.
