February 2020 – There has been a spike in mosquito activity due to warm weather. The adult rice field mosquitoes, Anopheles freeborni, have woken up from their winter nap. These pesky mosquitoes are aggressive biters, enter your home even though they are not welcome and are, well, annoying. These mosquitoes DO NOT carry West Nile virus. For more information, download our brochure on Anopheles.
