The Aston Township Health department would like to remind all residents to please eliminate any and all stagnate water from your property. Stagnate water attracts insects like mosquitoes that may carry the West Nile Virus. On the Pennsylvania West Nile Control Program Website a product named Bti is recommended for use in controlling the mosquito population. This product which can be found at many Home Improvement stores kills mosquito larvae and is not harmful to people, pets, fish, or plants.
