FREQUENTLY ASKED QUESTIONS
Ticks are the Problem
1) What other animals frequent the devices?
by the Shelter Island Deer and Tick Committee
Raccoons, squirrels, mice, chipmunks, turkeys, blue jays and other birds frequent the device. Hundreds of hours of 24-hour infrared videotape recordings documented by the ARS indicate that besides the deer, rac-
coons are the only animals to contact or rub the treated rollers. Because raccoons are also good hosts for ticks, those raccoons that do receive suffi cient treatment will also kill appreciable numbers of ticks.
2) How do we know how much corn a deer will eat?
The devices are intended to ‘bait’ the deer and not ‘feed’ them. For that
reason only clean whole kernel corn should be used for bait. Several
studies have shown that, in the presence of abundant natural browse,
corn is a self-limiting diet for white-tailed deer. Thus, when an abun-
dance of other natural food is available, a white-tailed deer will eat
The population of ticks on Shelter Island has greatly increased in recent
approximately 1 to 1 1/2 pounds of corn per 100 pounds of body weight
years causing a lot of serious illnesses in people of all ages. Tick popula-
tions of both the lone star tick and the blacklegged tick, previously called the “deer tick,” continue to spread throughout much of the country. As

star tick is much more aggressive than the deer tick and will track its host up to 30 feet. Tick-borne disease is a costly problem and one published study has estimated that Lyme disease alone may cost society over two billion dollars a year. It is now clear that controlling the tick population is by far the most effective way to reduce human tick-related illnesses.

to the environment than does the targeted application of the ‘4-Poster’.

There would be approximately one ‘4-Poster’ baiting station for every 50 acres or approximately 100 ‘4-Posters’ placed on the island. Each ‘4-Poster’ would be attended to at least weekly.
