The Department of Environmental Protection will spray open spaces in residential and recreational areas for mosquitoes in Hanover Friday.

In the event of rain, spraying will be done Monday, according to the DEP.

Spraying will be done by truck-mounted equipment to control the adult mosquito population.

The application materials have a very low toxicity profile to mammals and are safe for the environment, according to the DEP.

This treatment is a result of high trapping counts for the Asian tiger mosquito population. This type of mosquito does not typically carry West Nile virus.

However, mosquito samples in nearby Adams County have been identified with the West Nile virus so far this year, the DEP said.

You can help: Individuals can take a number of precautionary steps 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.

Additionally, these simple precautions can prevent mosquito bites:

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.
