Information to the Public
The District asks the public to help by inspecting homes and yards thoroughly and remove any standing
water that may cause mosquito production. By a thorough inspection of the premises, various standing
water situations could be found, such as fish ponds, bird baths, tin cans, water cans, saucers under potted
plants, old tires, clogged roof gutters, abandoned pools, uncovered boats, leaking faucets, watering
troughs, rain barrels, street gutters, house cooling units, tree holes, and water in basements during wet
years. Pumping of these basements is very important as we progress into the mosquito season.

The District requests that the public refrain from over watering their lawns to the extent that water will run off
into the street gutters and remain standing. Any of these standing water situations may be reduced by the
home re
sident. If any problem is too large for the resident to correct, they may call the District for help in
resolving some problems.
