For some unknown reason the CDC website has as its focus DEET, but there are arguably better repellants both from a safety and an efficacy perspective.

For instance consider the EPA registered repellants efficacy and % actives for Tick repellants:

DEET at 25% is approved for 5h protection

Picaridin at 10-20% is approved for 12-14h repellancy – depending on the formulation

By comparison to achive a 10h Tick protection with DEET you need to use 100% DEET

Bottom line here is that the CDC needs to be more telling about the facts and choices people have for Tick repellants. Their website and recommendations are slanted to a repellant that while effective and approved by the EPA, has some very real issues and concerns.

Very strong arguments can be made that Picaridin is a far better choice as a Tick repellant.

It is the nymphal ticks the most commonly vector the disease. See http://www.caryinstitute.org/sites/default/files/public/reprints/Price_2004_REU.pdf

The hens can also be a host for the small ticks and therefore be a potential source of tick population increase.

They will eat a few adult ticks and will keep enclosed areas pretty clean of adults, but it is the myphs at the forest edges that are the real problem.
