What can I do to reduce the number of mosquitoes where I live?

  1. Dispose of all water-holding containers, such as plastic jugs, empty barrels, tin cans, buckets, bottles, garbage, etc.
  2. Dispose of old tires. Old tires have become one of the most productive breeding sites in this country.
  3. Turn over canoes and small boats, or cover them with a tarp. If covering with a tarp, make sure tarp does not sag down and collect water.
  4. Cover trash containers, or drill holes in the bottom of recycle containers to keep rain water out.
  5. Empty wading pools weekly, or store them inside when not in use.
  6. Change water in birdbaths weekly.
  7. Keep drains and ditches clean so water will drain properly.
  8. Fill in any ruts or low spots that could collect and hold water for more than one week.
  9. If storing wheelbarrows outside, store upside down, or cover with a tarp.
  10. Keep grass cut short and shrubbery trimmed so adult mosquitoes don't hide in the shaded areas during the day.
  11. Fill in hollow stumps with sand or concrete.
  12. Inspect eave troughs to assure water is draining properly.
  13. Aerate ornamental pools, or stock them with fish. Water gardens may become major mosquito producers if allowed to stagnate.
