Special Note

• The Centers for Disease Control and Prevention (CDC) and Virginia Department of Health have expanded their recommendations for mosquito repellants to include Picaridin and oil of lemon eucalyptus. With proper use insect repellants will prevent you from being bitten from mosquitoes. Please note these products do not kill the mosquitoes, they only repel mosquitoes. It is normal for the mosquitoes to keep flying around you when using these products.
