Prevention of Lyme disease includes preventing tick bites. Ticks are most active in May, June, and July, so these are times to protect your children carefully. Ticks prefer wooded and bushy areas with high grass, so these are areas to avoid. If walking in areas such as these, stay in the center of the trail. Create a “tick-free zone” around playground equipment in your yard by moving leaf litter and brush away from areas where your children play. Pesticides and insect repellents can be helpful in geographic areas with large numbers of ticks. If you find a tick on your child, remove it carefully and call your physician to discuss whether testing or treatment is appropriate.
