While we embrace springtime, we see the return of mosquitoes. Warmer weather and standing water provide the perfect breeding grounds for these pests.
According to the
Placer Mosquito and Vector Control District (PMVCD), “Roseville wins the jackpot with mosquito activity nearly year-round”.
Here are three key mosquito behaviors:
-
This year, we’ve seen a surge in mosquitoes in late January and February. Those mosquitoes are dormant during the winter and come out in 60 degree/+ weather, thinking it is springtime. Now that it is springtime, we will see another emergence, after all this rain ends. These mosquitoes do not transmit common diseases.
-
We will also see the emergence of our “tree-hole” mosquitoes soon. During the winter, these mosquitoes are dormant as eggs in rotted out “tree-holes” (mostly oaks). The eggs hatch when the holes fill with rain and the temperatures get warmer. These do not transmit human diseases but can transmit dog heartworm.

-
What we are most concerned about are the mosquitoes that transmit West Nile virus. We have two species that do that. They typically emerge in the late spring, early summer, and start turning positive for
West Nile at the end of June.
Working outside often leads to mosquito exposure. To protect yourself, the PMVCD suggests that you:
- If possible, drain any standing water in the area.
- DEFEND yourself against mosquitoes by using an effective insect repellent, such as DEET, Picaridin, or Oil of Lemon Eucalyptus. They emphasize to make sure you follow label directions!
