PMVCD ramps up for increased mosquito activity

ROSEVILLE, Calif. – In preparation of another season of increased mosquito activity, the Placer Mosquito and Vector Control District has been busy with a variety of activities, including setting up sentinel chicken coops, placing mosquito traps throughout the county, training seasonal support staff, and boosting its mosquitofish supply, which should be available for the public in mid-May.

“This is a good time to remind Placer County residents that mosquito season is around the corner, since more people are starting to engage in warm-weather outdoor activities,” said Joel Buettner, District Manager. The District has seen an increase in service requests in the past few weeks, with the most recent warming trends.

Most current mosquito activity involves treehole mosquitoes, which develop in small water-filled holes in the trunks of trees, and in man-made containers. These black and white mosquitoes tend to remain close to the area where they developed, and female mosquitoes will aggressively try to bite people at any time of day. Treehole mosquitoes are the primary vectors of dog heartworm, which can be fatal for both dogs and cats that have not been given heartworm medication.

“It is no coincidence that warm weather, which brings people outside, also brings out mosquitoes and other vectors. Our goal is not only to control those vectors, but to educate Placer County residents about mosquito prevention so that we can all work together to decrease health risks associated with vectorborne disease,” states Buettner.

3 D’s of Protection
