PRECAUTIONS AGAINST MOSQUITO-BORNE ILLNESS:
1. Be aware that mosquitoes are most active between dusk and dawn. Take precautions to
minimize exposure during these hours.
2. Long sleeves and long pants can minimize risk of mosquito bites.
3. Insect Repellents including DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), IR3535 or oil of lemon eucalyptus [(p-methane 3, 8-diol (PMD)] should be used according to directions.
NOTE: DEET products should not be used on infants under 2 months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age. Permethrin Products are intended for use on items such a clothing, shoes, bed nets and camping gear and should not be applied directly to the skin.
4. Remove standing water in your yard where mosquitoes may breed.
Topsfield's Risk Level for West Nile remains LOW.
Topsfield Board Of Health’s approach remains on surveillance and education.
