Mosquito Spraying Set for Bristol and Falls Townships

The war on mosquitoes that can spread West Nile Virus will escalate with pesticide spraying set for two communities this week.

Crews will spray in Falls Township on Tuesday and Bristol Township on Wednesday. Spraying was originally set for Falls Township only but officials announced Monday that spraying will also be done in Bristol Township.

Two mosquitoes found in Bristol Township tested positive for West Nile Virus last week, according to the Pa. Department of Environmental Protection.

Crews are scheduled to spray the North Park section of Levittown and the Nottingham Village section of Fallsington between 7:45 and 10:45 p.m. Tuesday, according to a Phillyburbs report. 

Rain and hot weather this summer have provided standing water and good conditions for mosquitoes to breed. 

Two people in Bucks County were sickened by West Nile last year.

Tuesday's treatments will be administered via truck-mounted equipment, spraying residential and recreational mosquito habitat. The equipment dispenses a pesticide called Duet Dual-Action Adulticide at a rate of 0.75 ounces per acre.

The product is designed to provide quick, effective control of adult mosquito populations. The application material has a very low toxicity profile to mammals and will have negligible impact to non-target insects and the environment, according to the Department of Environmental Protection.

Weather conditions and other unexpected events could delay or cancel this spray operation. If conditions do not allow application on Tuesday, the following evening will serve as the back-up spray date.

Certain mosquito species carry the West Nile virus, which can cause humans to contract West Nile encephalitis, an infection that can result in an inflammation of the brain. According to the Pennsylvania Department of Health, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis.

In 2013, West Nile virus has been detected in the following counties: Adams, Beaver, Berks, Bucks, Dauphin, Delaware, Erie, Lackawanna, Luzerne, and Northampton.

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 as 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 larvae, 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 repellents according to the manufacturer's instructions. An effective repellent will contain DEET, picardin or lemon eucalyptus oil. Consult with a pediatrician or family physician for questions about the use of repellent on children, as repellent is not recommended for children under the age of two months.
