The more common Asian tiger mosquito tends to fly shorter distances (100 – 300 yards) which still allows it to invade your property from surrounding areas in your neighborhood. Pre-treatment surveys will need to be undertaken to determine where and when application is required, ensuring the product is applied at the correct stage of larval development. Non-chemical methods can significantly reduce populations, mainly by the elimination of breeding sites, which can be anywhere water is held such as swimming pools, swamps, dams, rock pools and anything which can hold water for some time. Mosquito chemical control can be in the form of spraying insecticides that target the adults, larva, or both. Although chemicals are widely used to treat Ae. Over-application can be costly, and whilst there is a reasonable safety margin for most chemicals, applying a chemical at a rate higher than that specified on the label may have a negative impact on the environment. 45, no.2 Journal of Vector Ecology 155 Exploiting the chemical ecology of mosquito oviposition behavior in mosquito surveillance and control: a review Victor Mwingira1,2, Leonard E.G. The advantages of larvicide application include: The active constituent in larvicide products used for mosquito control generally includes a bacterial toxin (Bti or Bs), an insect growth regulator (S-methoprene) or a combination of both. It is important to note that adulticides are not target-specific and will kill other insects, such as bees and dragon flies, and can also be lethal to fish. Our experts carry out a thorough inspection of the indoors and outdoors to determine the affected areas. Water-based diluents can be used, which are more environmentally favourable. For these reasons, larvicides should be considered the preferred option over adulticides, if chemical control is deemed to be the most appropriate management strategy. They are very specific, affecting only mosquitoes, black flies, and midges. Chemical insecticides have been widely used to control mosquito populations, but insecticide resistance to pesticides has become widespread in mosquito populations, making insecticides less effective over time.
