Solid and liquid baits were tested for the delivery of drugs to white-tailed deer. The solid bait was compromised of a mineral block paired with apple, peanut butter, or acorn extract. The liquid bait was compromised of water, apple juice, glycerine, salt, and either peanut butter or apple odor. Although both solid and liquid baits were attractive to deer, the latter may be more useful because consumption can be measured directly, ingestion by nontarget animals is minimized, and bait degradation by weathering is reduced.
