Ticks Don't Come Out In The Wash

Adult deer tick, Ixodes scapularis. (Credit: Scott Bauer)ScienceDaily =
(Oct. 11, 2007) =E2=80=94 Before venturing into tick-infested territory, =
you used a topical repellent on exposed skin and outer clothing. When =
you returned, you did a body check and threw your clothes in the wash. =
But clean clothes may not be tick-free clothes.=20
When he found a live lone star tick (Amblyomma americanum) on the =
agitator of his washing machine, Agricultural Research Service (ARS) =
entomologist John Carroll decided to find out how tough ticks are. So he =
bagged up nymphs from two species=E2=80=94the lone star tick and the =
deer tick, (Ixodes scapularis), the creature that transmits Lyme =
disease=E2=80=94and put them in the washing machine.=20
Carroll used a combination of water temperature settings and detergent =
types to wash the ticks. The majority of lone star ticks survived all =
the water-detergent combinations with no obvious side effects. Most of =
the deer ticks lived through the cold and warm water settings as well. =
But when one type of detergent was used with a hot water setting, only =
25 percent of the deer ticks survived.=20
When it came time to dry, all the ticks of both species died after an =
hour of tumbling around at high heat. But when the dryer was set to "no =
heat," about one-third of the deer ticks and more than half of the lone =
star ticks survived.=20
Carroll placed the ticks in mesh bags, which kept them from draining =
away during the rinse cycle and perhaps increased their odds for =
survival. However, ticks might also survive a sudsy interlude by =
sheltering in the folds and crevices of a typical load of laundry. Some =
tick species have been observed to survive hours of submersion in fresh =
water.
Both adult ticks and nymphs can transmit disease. Carroll=E2=80=99s =
research reinforces recommendations by the U.S. Centers for Disease =
Control and Prevention to wash and dry clothes at high temperatures =
after spending time in areas known to harbor ticks.
