The Montgomery County Health Department consulted with the Pennsylvania Department of Environmental Protection and Upper Gwynedd Township officials on the adulticide spraying, per the county health department.
The spraying will be done where sampling by the Health Department and the state DEP has shown mosquitoes that carry the West Nile Virus.
The spraying will be, weather permitting, on Wednesday from 7:30 p.m. to 9 p.m. The alternate date will be Tuesday, Sept. 24.
Residents within the spray area should consider remaining indoors, closing windows, and turning off ventilation systems that draw in outside air for the duration of the spray, plus 30 minutes after.
The area within the highlighted section of the photo will be sprayed with Biomist 3+15 ULV at a rate of 1.5 fluid ounces per acre applied with an ATV-mounted Ultra Low Volume sprayer.
The spraying will treat larvacide where mosquitoes are breeding.
Residents may contact the Health Department at 610-278-5117 if they are concerned about an area of standing water that may be a breeding area.
There are things that everyone can do around the home to help eliminate mosquito-breeding areas. Some of these tips include:
- Identify and eliminate all sources of standing water that collect on your property. Mosquitoes will breed in any puddle that lasts for more than four days.
- Dispose of tin cans, plastic containers, ceramic pots, or similar water holding containers that have collected on your property. Do not overlook containers that have become overgrown by aquatic vegetation.
- Pay special attention to discarded tires that may have collected water on your property. They can serve as a breeding ground for mosquitoes.
- Drill holes in the bottom of recycling containers that are left out of doors. Drainage holes that are located on the container sides collect enough water for mosquitoes to breed in.
- Have clogged roof gutters cleaned on an annual basis, particularly if the leaves from surrounding trees have a tendency to block drains.
- Turn over plastic wading pools when not in use. A wading pool becomes a place for mosquitoes to breed if it is not used on a regular basis.
- Turn over wheelbarrows and do not allow water to stagnate in birdbaths.
- Aerate ornamental pools or stock them with fish. Water gardens are fashionable but become major mosquito breeding grounds if they are allowed to stagnate.
- Keep swimming pools clean and chlorinated. A swimming pool that is left untended becomes a source of mosquito breeding. Be aware that mosquitoes may even breed in the water that collects on swimming pool covers.
