DEET does not poison ticks; it makes a host harder to find. The compound interferes with chemosensory neurons that respond to host-associated odors, particularly through Haller's organ. Concentrations above 50 percent give no extra protection, only longer duration.
The most effective personal protection against tick attachment in field studies is the combination of permethrin-treated outer clothing…
Ticks find hosts using Haller's organ, a sensory pit on the tarsus of each foreleg. It carries chemoreceptors tuned to ammonia, carbon…
Hard ticks find hosts by questing: climbing onto grass blades or low vegetation, anchoring with the back legs, and waving the front legs…
Tick saliva contains hundreds of pharmacologically active proteins that suppress the host's immune response, dilate blood vessels, prevent…
Tick tubes were developed by Sam Telford and Andrew Spielman's group at Harvard in the late 1980s. The original Massachusetts trials of…
Tick paralysis is caused by a neurotoxin in the saliva of feeding female Dermacentor or other tick species, not by any infection. Symptoms…
