Question: What do you do to limit attacks from pesky ticks and chiggers? — Charles H.

Answer:  You can use common DEET-based insect repellents that are sold under a variety of trade names like REPEL 100, Deep Woods OFF and Ben’s 100. However, their effectiveness is temporary. They do have odor, and although they are approved by the EPA, some folks shy away from the high-potency versions.

A better solution is one containing permethrin, found in products like Sawyer’s Permethrin Premium, REPEL Permethrin and Robinson Outdoors Bug Blocker for Ticks. Rather than applying to your skin, you treat your clothing (be sure to follow directions on the packaging). Spray it on, let it dry and the repellant will remain effective for a week or more.
