Do Mosquito Dunks Expire?
Whether you are trying to find a product that will keep mosquitoes away, or you simply want to make sure that you are not infected with the disease, you are probably wondering do mosquito dunks expire? These dunks are designed to prevent mosquitoes from breeding and to help kill larvae.
The dunks are made of a substance called BTI, or Bacillus thuringiensis subspecies israelensis. This bacteria is found in soil, and it is toxic to insects, including mosquitoes. It is also effective at killing black flies and fungus gnats. It is not harmful to humans or animals, and it is approved for pest control by the USEPA.
There are several forms of BTI, and it is commonly used by mosquito control personnel. It has been tested against 2,500 different species of mosquito larvae. It has also been tested against Asian tiger mosquitoes.
Mosquito Dunks are a patented formula, and are made by Summit Chemical Company. They contain BTI, and they can be purchased in packs of 20. Each Dunk will treat 100 square feet of water. The Mosquito Dunk can be placed in tree holes, rainwater barrels, and other places where standing water is an issue. They are also effective in preventing mosquitoes from breeding.
It is recommended that you place at least one Dunk in every ten square meters of dry surface. If you have a large body of water, you may need to place more than one.
It is also important to keep the Dunks out of direct sunlight and away from heat. Ideally, they should be stored in a sealed container. They should also be anchored with string or stakes.
