Damminix Tick Tubes® are biodegradable, cardboard tubes filled with permethrin treated cotton balls. Mice collect the cotton to build their nests. Deer ticks that feed on mice in the Spring and the Fall are exposed to permethrin and killed. All the while, the mice, other mammals and your lands are unharmed and undisturbed.It is well known that deer spread ticks infected with Lyme disease. However, did you know that these same ticks get Lyme disease from mice, not deer? Damminix Ticks Tubes® rely on the natural nesting instincts of mice to take the battle to source and deliver tick controlling permethrin directly to this host animal and the ticks it infects.
