Insecticides in aerosol form have become, since 1940, an important means of controlling insects. They were immediately adopted by the military forces to combat disease-carrying insects, such as the malaria and yellow-fever mosquitoes. Because of accelerated research and widespread use during the war period, the aerosol today is a household word and item. Aerosols are efficient when properly used because of the minimum of wastage.
Particles of an aerosol come in contact with an insect by settling on it through gravitational fall or by striking it through motion of the particles or the insect. When aerosols are used in confined spaces, such as a room, the contact is partly by the first method, and the time necessary for enough particles to accumulate on a resting insect to cause its death is related to the rate at which the particles settle.
The global household insecticides market is expected to increase at a CAGR of 7.9% over the forecast period to reach US$ 17,248.9 Mn by 2021. Household insecticides are manufactured in different forms and used for controlling various types of insects. Household insecticides formats used for controlling mosquitos and flies are aerosol/spray, electric, coils, others.
