After feeding and dropping off, the larvae molt to an eight-legged nymph. Nymphal activity begins in mid- to late spring and continues into September. After feeding, the nymph drops to the ground and molts to the adult. Unfed larvae and nymphs can survive for over 1 year without feeding. The duration of each stage is highly dependent upon temperature and humidity.
Seasonal activity is influenced by both day length and latitude.
Repellents and insecticide sprays judiciously used can greatly reduce tick attack. Contact your local lawn and garden dealer or local Extension office for current chemical recommendations.
