Years ago, it was discovered that by applying a perimeter strip of barrier/surface protection, mosquitoes (while they were physically capable) would would die when coming into contact with the barrier/surface application, thus giving an area of protection. This proved exceptionally effective for campgrounds; animal shelters, lots, parks, and
other areas where it was not feasible to put insecticide directly onto the site to be protected.

Explanation

     Using a campground as an example, a typical applicator would probably use a motorized mist blower (not a fogger) that would have a very high air volume to blow the mist 20-40 foot or, a tank sprayer having a higher pressure pump, either of which could produce mist particles in the 50-100 micron range (that is like a very fine mist). The person making the application would walk around the perimeter of the area to be protected - applying a light (not wetting) mist to the grass, foliage, shrubbery, etc. in about a 30 foot or more wide band. To do this, they would walk at a slow steady pace and move the outlet wand or sprayer nozzle from side to side - applying the light mist as they go.

MCI's Methods of Application

     Here at MCI, we use 2 different barrier/surface control sprayers, the Residual Alley Sprayer (RAS) and the Off-Road Large Area Sprayer (ORLAS). These were designed and engineered by Matt Welter of MCI and are used exclusively by MCI. Both of these sprayers are truck-mounted, allowing us to do barrier/surface control while on our regular TUG spray routes. They spray a fine, residual mist that coats the habitat and repels and/or kills the mosquitoes upon contact for up to 3 weeks, dependent on weather conditions (i.e. rain tends to wash it away). Each type of barrier/surface control sprayer has a different purpose, as is detailed below.

ORLAS

     This sprayer is very similar to the RAS, except for its range, which is up to 25 feet on each side of the truck (50+ foot band width). This allows us to spray areas that are inaccessible with typical spraying equipment. This sprayer is used more typically on the edges of town to lay down a wide barrier/surface of protection to help prevent additional adult mosquitoes from flying into the town area, but is also used for parks, playing fields, and other recreational areas in order to keep them as mosquito-free as possible.

P26

     High pressure system that produces proper droplet size to give the most effective long term residual in high foliage areas that mosquitoes are most likely rest.

RAS

     This sprayer is used to spray up to 8 feet from the truck onto brush, bushes, tall grass, etc, where adult mosquitoes hide when weather conditions are not optimal for them to be flying. This sprayer is used typically in alleys to spray habitats that are behind garages, sheds, etc.
