Eliminate Mosquito Breeding Areas

Do-it-yourself mosquito control is no substitute for a responsible community-wide mosquito control program. But, it can definitely help reduce the mosquito population in your own yard since some mosquitoes, such as the Asian Tiger Mosquito or the Southern House Mosquito, typically fly only a few hundred feet from their breeding areas.

Find and Eliminate Mosquito Breeding Sites

Mosquitoes breed in standing water. So the first, most important step in controlling them is to find all of the places where water can accumulate on your property.

Drain, fill, or eliminate sites that have standing water:

  • Person cleans out a clogged house gutterClear out weeds, leaves, dirt, and other debris from pipes, especially those under a driveway. Make sure that water does not stand inside or near the ends of the pipe.
  • Drain or fill any low places, such as potholes, on your property where water collects and stands for more than 5 to 7 days.
  • Inspect septic drain fields. Do not allow water to accumulate on the ground surface.
  • Repair leaky pipes and outdoor faucets.
  • Clean out rain gutters and downspouts regularly. Clogged gutters are one of the most overlooked breeding sites for mosquitoes around homes.
  • Use mosquito control products specifically labeled to treat small areas of water that can not be drained. Such products contain an active ingredient such as Bti (Bacillus thuringiensis israeli) or methoprene that will not harm humans, animals, fish, or vegetation when used as directed. Such products are sold at local lawn and garden/home improvement stores.

Empty or throw away containers that have standing water – Tip or Toss

  • Clean out rain gutters and downspouts regularly. Clogged gutters are one of the most overlooked breeding sites for mosquitoes around homes.
  • Empty and turn over containers that hold water such as cans, jars, drums, bottles, flower pots, buckets, children's toys, wheel barrows, old appliances, plastic sheeting or tarps used to cover objects like grills or swimming pools, etc.
  • Make sure that all permanent water containers such as wells, septic tanks, cisterns, water tanks, and cesspools are tightly covered and insect-proof.
  • Place screens over rain barrels so that adult female mosquitoes can not lay eggs there.
  • Root or grow outdoor plants in sand or soil instead of water only.
  • Change the water in bird baths (and flower cuttings) at least once a week.
  • Clean out and change the water in your pet's water bowl or trough every day.
  • Cover trash containers/garbage cans to keep rainwater from accumulating.
  • Keep boats and canoes drained and covered/overturned. Make sure that tarps or other covers do not hold water.
  • Drain or get rid of old tires by recycling them.
  • Drill holes in tire swings so rainwater will drain out.
  • Repair any leaky pipes or faucets.
  • Stock ornamental pools/ponds with mosquito-eating minnows, and keep vegetation trimmed from the edge of the pond.
  • Maintain swimming pools with proper pool chemicals or drain them completely if they are not in use.
  • Completely empty and clean out children's wading pools at least once a week. Keep children's wading pools empty and on their side when not in use.
  • Pack tree holes and hollow stumps with sand or cement.
  • If you need help locating mosquito breeding sites on your property, contact your county's local mosquito control program for help.

Other Tips to Protect Yourself from Biting Mosquitoes

Use screens on windows, doors, and porches.

  • Use screens (16-18 mesh per inch), in good repair, on windows and doors. Screen doors should open outward and close automatically.
  • To protect infants, use white-colored mosquito netting made of cotton or nylon with 23 to 26 mesh per inch.

Avoid mosquitoes.

  • Most mosquito species bite during dawn, dusk, twilight hours, and night. However, some species bite during the day, especially in wooded or other shaded areas. Avoid exposure during these times and in these areas.
  • Avoid wearing perfume or scented products.
  • Keep car windows rolled up and garage doors closed at night.
  • Use yellow light bulbs or sodium vapor orange lights for outside lighting.

Wear insect repellent or protective clothing.

  • Wear an insect repellent that provides protection for the amount of time that you will be outdoors.
  • Children usually do not notice mosquito bites while engaged in play. Make sure children are protected with mosquito repellent.
  • Treat clothing with a repellent as directed on the label to provide temporary protection. Never apply a repellent underneath clothing.
  • Treat clothing with permethrin as directed on the label to provide protection even through several wash cycles.
  • Wear light-colored clothing rather than dark colors.
  • Wear a long sleeved shirt and long trousers made of tightly woven fabrics.
  • Tuck the pants' cuffs into your socks or boots.

Reduce the numbers of adult mosquitoes around your home.

  • Get rid of places where adult mosquitoes can find cool, dark, and damp areas to rest by mowing the lawn, trimming shrubbery, and cutting down weeds and vines, such as ivy, in the yard and next to the house.
  • For temporary relief outdoors, use a small hand-held fogger (not a garden sprayer) made for mosquito control. The foggers come with a special insecticide. Use it a few hours before an outdoor activity is planned, but fogging will not be effective on a windy day. When used as directed, it should kill the mosquitoes that are flying in the area at the time. Twilight is the most effective time to use a fogger outdoors.
  • Heat-activated repellent pads or mosquito coils may be somewhat effective in repelling mosquitoes in a small area such as a patio. Read and follow all label directions.
  • Electrocuting devices or bug zappers that use ultraviolet light to attract bugs are not effective against mosquitoes. Bug zappers mainly kill beneficial moths, beetles, and other harmless night-flying insects.
  • Citronella smoke can reduce the number of mosquito bites - but only for people who stand very close to the candle or Tiki torch.
  • The Citrosa plant does not contain citronella. It is actually a scented geranium that does not repel mosquitoes.
  • Devices that use ultrasonic waves to repel mosquitoes do not work.
  • Garlic or taking garlic pills by mouth do not repel mosquitoes.

Protect pets from deadly heartworms carried by mosquitoes.

  • Heartworm is a filarial worm (nematode) that can clog the heart and major blood vessels leading from the heart, which reduces the blood supply and oxygen to organs.
  • Your veterinarian can prescribe medicine to prevent heartworms.
  • Using medicine to prevent heartworms is a much better option than having to treat your pet for heartworms, which can cause severe toxic reactions in your pet.
  • Heartworms occur in both dogs and cats, although they occur more frequently in dogs. Cats are at most risk for heartworms when many infected dogs are around or if the cats are sheltered. The effects of heartworms in cats are usually more severe than in dogs. Cats can not be treated for heartworms, so prevention is the key.
  • Do not give your cat the same medicine your dog gets for heartworm prevention, as their needs are different.

If you have done all you can to reduce the number of mosquitoes around your home, but are still bothered by them, they may be breeding somewhere beyond your property. Contact your local mosquito program for help.
