DEDHAM, Mass. — Opossums are nocturnal critters that may repel and disgust many, but they could be a important factor in keeping ticks and Lyme disease at bay.
While some recommend spraying for ticks in your yard, opossums could be the natural key to warding off ticks.
According to a study published in the Proceedings of the Royal Society B, opossums kill around 90 percent of the ticks that attempt to attach and feed on them.
The study notes opossums are particularly good at grooming themselves, which leads them to swallow most of the ticks that attach themselves.
Based on a study conducted by the Cary Institute of Ecosystem Studies, researchers estimated opossums can kill about 5,000 ticks in one season.
"They're net destroyers of ticks," Cary Institute researcher Richard Ostfeld told NewsTimes.com.
Opossums are known for their ‘play dead’ tactic and that’s why some researchers urge people to avoid hitting opossums apparently lying dead in the road.
Avoiding killing opossums could be a simple way of helping attack the tick population in your area.
According to the Dallas-Fort Worth Wildlife Coalition, "Opossums eat fruits, snakes (opossums are immune to all types of snake venom, except that of the coral snake), insects, snails, slugs, eggs, mice, rats, fish, frogs, crayfish, and carrion. If for no other reason than pest control, opossums are great to have around!"
Opossums are the only marsupial native to North America.
