Help Prevent Mosquitos

In Colorado, a mosquito can complete its aquatic life cycle in as little as five days depending on the water temperatures and food supply available to them. Breaking their life cycle within this time period is typically the most effective and efficient means of mosquito control. Here are some things you can do around your house to prevent mosquitoes from breeding. Start by getting rid of places where mosquitoes can breed, such as:

In Standing Water

• Dumping standing water is essential to preventing mosquitoes and mosquito-borne illnesses. Mosquitoes can lay their eggs in as little as 1/4" of standing water. Some mosquitoes will even lay their eggs in water inside homes!   
• Don't allow any outside water to stand for more than four days.
• Cover rainwater barrels with mesh or screen.
• Drill holes in the bottom of any unused containers, so water can't collect.
• Remove or drain any standing water from birdbaths, discarded tires, flowerpots (check the dish underneath the flowerpot), wheelbarrows, barrels, tin cans that are left outdoors.
• Keep decorative fountains operational or drain the water. Check fountains after rain and at least twice a week.
• Change water in animal watering dishes at least twice a week.

Swimming or Wading Pools

• Immediately remove any water that collects on pool covers.
• Make sure the pool's pump is circulating water properly.
• Turn over wading pools when not in use.
• Don't leave out children's toys, cups, etc.

Around Your Yard & Lawn

• Fill in any low depression areas in lawns.
• Check knots in trees.
• Repair leaky pipes and outside faucets and remove air conditioner drain hoses frequently.
• Remove areas such as dense shrubbery where mosquitoes breed and rest.
• Try to keep mosquitoes out of the house
• Make sure that door and window screens fit tightly and do not have holes.
• If there are no screens, keep doors and windows closed from evening to dawn.

Personal Protection From Mosquitoes

• Stay indoors from dusk to dawn when mosquitoes are most active. If you need to be outdoors during this period, cover up and use insect repellent for extra protection.
• If you like to work in your garden, avoid early morning and evening when mosquitoes are most active.
• Wear long-sleeved shirts, long pants and socks when outdoors during these active times. 
• It's a good idea is to spray any clothing with repellents containing DEET, as mosquitoes easily bite through thin clothing such as cotton t-shirts.
• Carefully read and follow the manufacturer's directions for use
