Mosquitoes don’t respect fences—they fly freely from yard to yard, spreading disease across Orange County. That’s why eliminating standing water on your property isn’t enough—we all need to pitch in. Help protect your community: dump and drain any standing water you find.
그만큼 Orange County Mosquito and Vector Control District (OCMVCD) works year-round to stop mosquitoes from breeding and biting, while educating the public and controlling the spread of mosquito-borne diseases.
Fast Facts
- Mosquitoes need water to breed—just five to seven days is enough to complete their life cycle.
- Most mosquitoes come from small backyard sources: birdbaths, buckets, bromeliads, plant saucers—even a bottle cap.
- Only female mosquitoes bite, and their bites can transmit diseases to people and pets.
- Adult mosquitoes rest in grass and shrubs but don’t breed there.
