Many people have noted an increase in mosquitoes this year. In particular, we seem to have a large number of the small the ankle-biter types.
Nate Stigman from Vector control has just checked the Amapola slope drainage ditch and did not find any mosquito larva. There is some stagnant water present but it is moving slowly. He said that the mosquitoes are most likely coming from homeowner’s lawns and ponds.
These small invasive species can breed in stagnant water as small as a bottle cap. Please check your property for any possible breeding environments. Water features can be easily and safely treated using a product like Mosquito Bits.
It seems that these small non-native mosquitoes can breed in almost any moisture, even lawns. Here is a pretty good link on mosquitoes and treatments.
