This spray works well in repelling ticks, including deer ticks. Made with essential oils, neem oil, caster oil. Do not use on children under 8 years of age. Instead use the fly and mosquitoe lotion to help.  The oils in this are different than the oil for fly and mosquitoe. However children of an early age must not use the oils we can as adults. This spray is put to the test up in Northern Wisconsin on us and our dogs. Works very well. DO NOT USE IF PREGNANT. Instead use Baby Fly and Mosquitoe Lotion
