Mosquito traps (nonfiction)

Mosquito traps are devices and techniques for trapping mosquitoes.

Trapping adult mosquitoes

Watter drowning traps

Water drowning trap: add detergent to a pool of water. The detergent eliminates water surface tension: mosquitoes landing on the water will fall in and drown.

Flypaper traps

Flypaper may be useful. Consider an arrayed of closely spaced flypaper strips.

Fan traps and attractants

Fan trap: use a box fan to overpower mosquito flight, drawing mosquitoes to a filter; use isopropyl alcohol or other toxin to kill the mosquitoes. See DIY Mosquito Trap that Actually Catches Mosquitoes @ YouTube.

Some newer mosquito traps or known mosquito attractants emit a plume of carbon dioxide together with other mosquito attractants such as sugary scents, lactic acid, octenol, warmth, water vapor, sounds [details needed], and light. By mimicking a mammal’s scent and outputs, the trap draws female mosquitoes toward it, where they are typically sucked into a net or holder by an electric fan where they are collected. According to the American Mosquito Control Association, the trap will kill some mosquitoes, but their effectiveness in any particular case will depend on a number of factors such as the size and species of the mosquito population and the type and location of the breeding habitat. They are useful in specimen collection studies to determine the types of mosquitoes prevalent in an area but are typically far too inefficient to be useful in reducing mosquito populations.

Trapping mosquito eggs and nymphs

A traditional approach to controlling mosquito populations is the use of ovitraps or lethal ovitraps, which provide artificial breeding spots for mosquitoes to lay their eggs. While ovitraps only trap eggs, lethal ovitraps usually contain a chemical inside the trap that is used to kill the adult mosquito and/or the larvae in the trap. Studies have shown that with enough of these lethal ovitraps, Aedes mosquito populations can be controlled. A recent approach is the automatic lethal ovitrap, which works like a traditional ovitrap but automates all steps needed to provide the breeding spots and to destroy the developing larvae.

In 2016 researchers from Laurentian University released a design for a low cost trap called an Ovillanta which consists of attractant-laced water in a section of discarded rubber tire. At regular intervals the water is run through a filter to remove any deposited eggs and larva. The water, which then contains an 'oviposition' pheromone deposited during egg-laying, is reused to attract more mosquitoes. Two studies have shown that this type of trap can attract about seven times as many mosquito eggs as a conventional ovitrap.
