Mosquito Season

Prevention
Take steps now to lessen the likelihood of mosquito bites:
- Limit time spent outdoors at dawn or dusk, when mosquitoes are most active.
- Wear lightweight, long-sleeved shirts and long pants while outdoors.
- Spray clothing with insect repellent since mosquitoes may bite through clothing.
- Install or repair window and door screens to keep mosquitoes out.
- Apply insect repellent to exposed skin. Always read and follow product directions.

Don't Breed Mosquitoes!
Mosquitoes lay eggs in still water which hatch in seven to 10 days. Check out these tips to reduce the number of mosquitoes in and around the house.
Report Dead Birds
Dead birds may be a sign that West Nile virus is circulating between birds and the mosquitoes in an area. If you find a dead bird in your neighborhood, please report the bird by calling the Colorado Help Line (CDPHE), 877-462-2911. Remember, if you need to move the bird, avoid bare-handed contact and use gloves or an inverted plastic bag to place the bird carcass in a garbage bag.
