Every situation is different. Ticks may be more difficult to repel than mosquitoes. Some pests are more active at certain times for example, many mosquitoes are most active between dusk and dawn. Ticks may be active at any time of day. Some places are more likely to have higher activity, too mosquitoes generally live in areas with brush and trees.
Ticks prefer areas with tall grass, brush and trees.
The longer you are out, the more protection you may need. Some people exposed to high numbers of ticks and mosquitoes for long periods of time use a two-part approach. With this approach, about 33 percent DEET in a controlled release formula is applied on exposed skin, and clothing is treated with permethrin. If, on the other hand, you are going to do some yard work or have a picnic during mid-day when mosquito activity is low and you decide to use an insect repellent, DEET concentrations as low as five percent may provide sufficient protection from mosquito bites for up to about four hours. For example, some areas have deer ticks that can transmit the bacteria for Lyme disease.
