County to Spray for Mosquitos Monday in Morrisville

Morrisville Borough will be sprayed for mosquitos Monday due to high populations of insects with West Nile virus found there earlier this month.

Twice in July, mosquitoes in Morrisville tested positive for the virus. 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.

The Bucks County West Nile Program, which announced the spray on Friday, will be conducting an ultra-low volume mosquito control operation via truck-mounted equipment, spraying residential and recreational mosquito habitat.

The equipment dispenses Masterline Kontrol 4-4 at a rate of 0.75 ounces per acre, according to information provided by county health officials.

“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,” a county press release said.

In 2014, West Nile virus has been detected in the following counties: Adams, Beaver, Berks, Blair, Bucks, Carbon, Centre, Chester, Cumberland, Dauphin, Delaware, Erie, Franklin, Lancaster, Lehigh, Luzerne, Lycoming, Monroe, Montgomery, Northampton, Northumberland, Philadelphia, Schuylkill, and York.

In the event of unfavorable weather conditions, the spray will be held the next day.

County health officials offer the following tips 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.
