CHICO — Each year, usually around February, the Butte County Mosquito and Vector Control District gets a flood of calls from concerned residents about the sudden jump in the mosquito population.
While there are certainly more of them in the air lately, the ones that appear in February are known as the Anopheles Freeborni mosquito. They are pests, but the good news is that they do not carry West Nile Virus, said Maritza Sandoval, the district’s office manager.
According to the district, this is normal.
Sandoval said the anopheles mosquito generally goes looking for a blood meal any day that reaches 65 degrees or higher.
