Cumberland County is now up to 12 mosquito samples testing positive for West Nile virus, according to the county’s Vector Control office.
The positive samples were collected from East Pennsboro, Hampden and Shippensburg townships, as well as Carlisle, Camp Hill and Lemoyne boroughs.
The county Tuesday said Vector Control is keeping a close eye on the mosquito population and frequently gathers samples for testing. The office has applied more than 80 applications of mosquito control product to potential water breeding grounds.
The county also asks residents take steps to prevent mosquitoes from breeding. Residents should survey their property and get rid of stagnant water.
Containers should be emptied every five days to prevent adult mosquitoes from emerging, according to Vector Control. For sources of water that can’t be drained, they should be treated with mosquito dunks that contain Bacillus thuringiensis israelensis to kill larvae. The products are safe around humans and pets.
