Quick answer
Blacklegged Ticks feed on the blood of mammals, birds and reptiles, adjusting with season, age, and what is abundant in Deciduous forests, leaf litter, and grassy edges of eastern North America. That label is a preferred pattern, not every item an individual might sample.

Blacklegged Tick diet overview
Blacklegged Ticks (Ixodes scapularis) are best summarised as Blood — feeds on mammals, birds, and reptiles. Anatomy and habitat (Deciduous forests, leaf litter, and grassy edges of eastern North America) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How blacklegged ticks find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Blacklegged Tick role in the food web
As consumers in their food web, blacklegged ticks move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild blacklegged ticks. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Three-host life cycle
Blacklegged ticks feed once at each life stage — larva, nymph, and adult — dropping off between hosts to moult. White-tailed deer are critical adult hosts that distribute ticks, while mice and birds infect nymphs with Lyme bacteria during larval and nymphal feeds.
Questing behaviour
Ticks climb vegetation and extend front legs to latch onto passing hosts — a behaviour called questing. They detect carbon dioxide, heat, and vibration. Permethrin-treated clothing and DEET repellents reduce attachment during hiking.
