Sawyer recommends taking each item outside and coating it until the moisture causes the fabric to darken. At that point, the permethrin needs to fully dry before something is worn. According to the TickEncounter Resource Center permethrin fact sheet, a pound person would have no adverse health effects even if exposed to 32 grams of permethrin in a day, and a bottle of clothing treatment has less than 1 gram of permethrin. But it is important to know that permethrin is toxic to cats.
We tested both, and they do have advantages. Repellent lotions have two major downsides. There is no way to get them onto your shoes or boots for added tick protection. The same goes for a backpack or a tent. Second, Conlon told us that after application, lotions take about 20 minutes to start repelling bugs.
Sprays, like those we recommend, are more immediately effective. The upside of a lotion is that its effectiveness lasts longer than that of a spray. The lotion may also be easier to apply to difficult areas, like the back of the neck, or on a particularly squirmy child. As with the spray bottles, Sawyer has the widest selection of sizes, ranging from single-use packets to a 1-gallon container. Proven is available in 2-ounce and 6-ounce versions.
So there are advantages to take note of, but we think most people would be better served by a spray repellent. Deep Woods Dry is the better of the two, but the spray is thick, and it puddled on our arms. The regular Deep Woods is oily and smells pretty bad. We made the mistake of giving it a single squirt in a closed room, and we could still smell it an hour later.
We found it to be even more unpleasant when it was on our arms. At the other side of the concentration spectrum are products like Off!
