Mosquitoes in Castaic

May contain: building, villa, house, housing, pool, and water
Are you experiencing more mosquito bites? You might be dealing with the Invasive Aedes mosquito also known as the "ankle biter."

Aggressive, daytime "ankle-biting" Aedes mosquitoes continue to infest communities throughout California, including the community of Castaic. Their egg-laying behavior makes them impossible to eradicate but we can learn to control them with what we know.

Aedes mosquitoes thrive in our neighborhoods, especially in yards and patios.

Aedes mosquitoes lay their eggs along the water lines found in containers.

Aedes mosquitoes only need a spoonful of water to breed 100s of more mosquitoes.

Ways to Take Action Against Mosquitoes

1. Eliminate Breeding sources

Remember - mosquitoes only need a spoonful of water to breed 100s of more mosquitoes. Scan your home and yard for containers that catch water (i.e. plant sauces, buckets, yard drains, rain gutters) and #TipTossTakeAction! A mosquito can go from egg to adult in only 5-7 days so it's important to eliminate sources weekly.

Use repellent with one of these four active ingredients recommended by the CDC and EPA-approved: Picaridin, Oil of lemon eucalyptus, DEET, or IR3535. Did you know most of these can be used on children as young as 6 months old? Remember to read the label for proper application!
