Pesticide Spraying Did Take Place Thursday

Mosquito-control spraying by the state that was scheduled for Thursday did take place, despite some rain that night.

The Department of Environmental Protection has confirmed that fact, said Larry Taltoan, Radnor Township's Health Official. The spraying was set for parts of Haverford and Radnor townships (see map).

The treatments were to be administered by truck-mounted equipment to spray residential and recreational areas. The equipment dispenses Biomist 3+15 at a rate of 0.75 ounces per acre.

Mosquito samples in 41 counties have been identified with the West Nile virus so far this year. Five human cases have been confirmed in Delaware, Montgomery, Philadelphia and York (2) counties.

Individuals can take a number of precautionary measures around their homes to help eliminate mosquito-breeding areas, including:

• Dispose of cans, buckets, plastic containers, ceramic pots or similar containers that hold water.

• Properly dispose of discarded tires that can collect water. Stagnant water is where most mosquitoes breed.

• Drill holes in the bottom of outdoor recycling containers.

• Have clogged roof gutters cleaned every year, particularly if the leaves from surrounding trees have a tendency to plug drains.

• Turn over plastic wading pools when not in use.

• Turn over wheelbarrows and don’t let water stagnate in birdbaths.

• Aerate ornamental pools or stock them with fish.

• Clean and chlorinate swimming pools not in use and remove any water that may collect on pool covers.

If a resident has stagnant pools of water on their property, they can buy BTI products at lawn and garden, outdoor supply, home improvement and other stores. This naturally occurring bacterium kills mosquito larva but is safe for people, pets, aquatic life and plants.

Additionally, these simple precautions can prevent mosquito bites, particularly for people who are most at risk:

• Make sure screens fit tightly over doors and windows to keep mosquitoes out of homes.

• Consider wearing long-sleeved shirts, long pants and socks when outdoors, particularly when mosquitoes are most active at dawn and dusk, or in areas known for having large numbers of mosquitoes.

• When possible, reduce outdoor exposure at dawn and dusk during peak mosquito periods, usually April through October.

• Use insect repellants according to the manufacturer’s instructions. An effective repellant will contain DEET, picaridin or lemon eucalyptus oil. Consult with a pediatrician or family physician for questions about the use of repellant on children, as repellant is not recommended for children under the age of two months.
