5 Questions with Heather Patterson

1. Is the demand for mosquito services growing across the country?

Yes. Mosquito control services continue to be a fast-growing segment. Warmer temperatures, shifting rainfall patterns, expanding urban development, and the spread of problematic species into new areas are all contributing to this trend. In 2025, we saw the continued expansion of Aedes aegypti into new areas of the country, along with widespread reports of heavy mosquito pressure around the U.S. As a result, more companies are offering seasonal mosquito services to reduce pressure around residential properties so homeowners can get back to enjoying time outside.

2. What areas should technicians focus on when treating a property for mosquitoes?

Successful mosquito control starts with understanding where the mosquitoes are developing, resting, and spending their time during the heat of day. Inspections and applications should focus on targeting the breeding sites (look for pots, tarps, plant saucers, bird baths, and other sneaky containers around the property that collect and hold water), and areas where adult mosquitoes typically rest (think cool and shady, like dense shrubs and vegetation).

3. What products does CSI offer for mosquito management services?

CSI offers a range of products designed for different applications and service models for mosquitoes, including barrier treatments, ULV applications, and misting systems. Some examples include DuraFlex® ZC (combination chemistry product for backyard barrier treatments), Mosquito Mist Ultra (a ULV concentrate that targets mosquitoes in flight), and Vector Kleer (CSI’s first 25(b) minimum risk product).

4. How does a 25(b) product like Vector Kleer add value to a mosquito service?

Since 25(b) exempt products are considered minimum risk pesticides by the EPA, they can help companies meet the growing demand from homeowners who are interested in “green” service options using essential oil-based formulations. Vector Kleer is labeled for outdoor premises applications and for use in misting systems, giving applicators flexibility across a variety of service models to manage important vector pests.

5. What pests are on the Vector Kleer label?

Vector Kleer is labeled for and effective against important public health and nuisance pests like mosquitoes, ticks, fleas, and flies. Backed by efficacy data, Vector Kleer met or exceeded the requirements of state pesticide regulatory agencies following efficacy guidelines created by the Association of American Pesticide Control Officials.
