            From time to time insect repellent is prudent for students during outdoor activities to protect them from mosquito bites. The danger from insect bites particularly the mosquito is a virus which may cause West Nile illness.   

Guidelines for products use:

  1. No aerosols or pumps used indoors or with any elementary students. Accidental contact with eyes and persons with respiratory sensitivities may have adverse affects. Towelettes, sticks, clip on, wrist bands are acceptable.
  1. Label with the students name
  1. Students must be able to apply themselves
  1. Parent Permission for elementary students is required. Notes to be kept by the teacher. 
  1. Do not apply directly to face – put on hands and then apply. Avoid eye and mouth contact.


Consider encouraging long sleeves and long pants to protect the skin particularly for short periods of outdoor activity. Most vulnerable time for mosquito bites is between dusk and dawn – limited outside activity before 10:00 AM and after 6:00PM is recommended. Use product appropriate to the amount of time outdoors. Products with DEET, Picaridin and oil of lemon eucalyptus are most effective. Products with Permethrin should only be used on clothes. Do not use on skin which will be covered by clothing.

 In general – the higher the concentration of DEET the more effective, higher concentrations are most useful for extended periods of time outside. Lower concentrations are effective for shorter periods of time. Most are not recommended for children under the age of 3 years. – check the labels
