Add Dauphin County to the growing list of Pennsylvania counties that tested positive for West Nile Virus in 2019.

Dauphin County recommends the following:
- Buy products with Bti (Bacillus thuringiensis israelensis) – a naturally occurring bacteria that kill mosquito larvae but are safe for humans, pets and plants – for stagnant pools of water in the grass and garden.
- Remove any standing water in pots, containers, pool covers, tires, wheelbarrows, curving pools, roof gutters and other containers that hold water.
- Make sure screens fit snugly over doors and windows to prevent mosquitoes outside homes.
- Consider wearing long sleeved shirts, long pants, and socks when outdoors, especially when mosquitoes are most active at dawn and dusk, or in areas known for having a large number of mosquitoes.
- Reduced exposure of outdoor dawn and dusk during peak mosquito periods, typically April to October.
- Use insect repellents according to the manufacturer's instructions. An effective repellent will contain DEET, picaridin or lemon eucalyptus oil. Consult a pediatrician or family doctor if you have questions about the use of repellent on children, as the repellent is not recommended for children under the age of two months.
"Although the risk of contracting West Nile mosquito-borne virus is small – especially the elderly and people with compromised immune systems – they should try to reduce their risk," says Commissioner George P. Hartwick, III.
