One of the fastest growing segments of the pest control business throughout the America is the installation of mosquito misting systems. Such pest control system have grown increasingly popular in the past few years due to concerns over West Nile virus and other mosquito born diseases. Some see these systems as a way to take personal control over mosquito problems in communities that have reduced or eliminated community spraying activities.

Mosquito misting systems consist of a series of high pressure tubes and nozzles installed around a residential or a commercial area, connected with a pesticide reservoir, pump and timer, these misting systems come on one or more times a day depending upon the population of mosquitoes / pest to produce a fine mist of insecticide that kills them.

The working principle behind this Pest control system is simple. The mister nozzles break the spray solution down into very fine particles (50 micron or less size) which remain suspended in the air for varying lengths of time. It is estimated that in still air a droplet of 50 micron diameter (about half the width of a human hair) requires about 3.5 minutes to fall 3 feet (approx 1 meter). The idea is that flying mosquitoes /pests present in the air at the same time as the insecticide particles will contact the droplets and die on contact with the insecticide. Depending on wind speed, the mist may persist in the air for 1 to 15 minutes, killing mosquitoes and other flying insects.

All mosquito misting systems work in almost similar manner. For misting systems to work they must disperse an insecticide capable of killing small insects / Pests / mosquitoes. The Mosquito systems are engineered to allow the operator the ability to kill and control mosquitoes without having to measure and mix chemicals. Once the nozzle quantity and spray times are entered, its automated system will pump the desired amount of concentrated insecticide into a vented mixing tank plumbed to water. The pest control system can be programmed for on demand only. Two to three minutes per day on average should provide good initial results and should be reduced and tailored as per the users need.

As far as safety to humans is concerned, pyrethrum the main ingredients of any mosquito misting systems and are considered non-hazardous to humans and other mammals, including dogs and cats if used in an appropriate amount.
