Preventing Mosquitoes in Your Backyard
Simple tasks done on a regular basis will help protect your home against mosquitoes.
Did you know that most mosquitoes lay "egg rafts" and that each one can contain between 100 to 400 eggs?
It only takes approximately seven days to go from egg to adult mosquito. Therefore here are some easy steps to help control mosquitoes in your backyard.
Stock with mosquitofish. Add goldfish for looks if desired. Avoid spraying with garden insect sprays. Remove leaves and thin out pond lilies. Keep water level up. Screen inlet of recirculation pump. Chlorine kills fish-- transfer fish to glass bowl when cleaning pond. If pond is no longer desired, break holes in bottom and fill with dirt or sand.
Concrete or Plastic Swimming Pools
Operate filter and skimmer everyday to remove mosquito egg rafts and larvae. Provide drainage for filter and pump sumps. Chlorine will NOT kill mosquito larvae. If pool cover is used, keep it tightly sealed. Remove rainwater from top of pool cover. Stock unused or "out-of-order" pools with mosquitofish.
Prevent accumulation of bilge water. Store small boats upside down or cover to keep out the rain and water from sprinklers.
Other kinds of Containers
Remove and dispose of all unused containers that will collect rain or water from sprinklers.
- Old Tires
- Tubs, etc.
Home gardeners rooting plant cuttings in vases, buckets, etc. should change water every week.
Usable containers should be stored upside down.
