Culex pipiens and Culex tarsalis




Two types of mosquitoes that will start to be seen these early spring days, are Culex pipiens and Culex tarsalis mosquitoes. The Culex mosquito usually overwinters in all life stages, egg, larvae, pupae and adult. Adult Culex will emerge from diapause, when optimum temperatures are met. The aquatic stages for the Culex mosquito, egg, larvae, and pupae, all advance during the warming days, and strive to reach the adult stage. The female Culex mosquito will seek a blood meal not long after emerging, to produce eggs. Her eggs are laid in a cluster that resembles a raft, on the surface of a water source. Eggs will then hatch after a period of time, and emerge as 1st instar larvae. The larvae will go through three more stages and a pupal stage. Adults will then emerge and the cycle is repeated again and again if left unchecked.

Warmer days will bring us out and into the outdoors on a more regular basis. This is the time that the Colusa Mosquito Abatement District asks everyone that is out and about to keep an eye out for mosquito breeding sources. These can be something as small as a pets forgotten water dish in the backyard, to an abandoned swimming pool. Anything that can hold water for a period of time is prime habitat for the Culex mosquito.

The Colusa Mosquito Abatement District has begun their surveillance program, and will implement their larval control as needed. The districts adulticide program usually starts the end of June and runs to the middle of November. Please see the district's spray schedule on the Services tab above.

The Colusa Mosquito Abatement District asks that if you are spending time outdoors, to use prevetitive measures such as repellants, long sleeve shirts, and long pants. Please feel free to contact the district if you have any questions or concerns.
