Entomology Report January 2007, San Mateo County Mosquito Abatement District

The insecticide Suspend (Deltamethrin) was evaluated for its ability to control Dermacentor ticks along a recreational trail in San Mateo County. Three days post treatment, showed a 98% decline in ticks. One week post treatment resulted in 100% control and after seven weeks the trail was still at a density of 0 ticks. This study showed that the material is very effective in controlling Dermacentors. In the future, another study will be performed to evaluate the efficacy of Suspend on Ixodes pacificus ticks.
