Doing some research on ticks can go a long way. Most ticks survive in their nymph form by living on smaller rodents. Mice and chipmunks for example. There is a product out called Tick Tubes that you put out in your yard. These basically have cotton balls or other fibrous material in them that has been treated with permethrin. The idea is that the little rodents take the fibrous material to use for nesting. This kills off the tick nymphs reducing the population at the source. The commercial tick tubes are not cheap but you can make a very affordable version out of toilet paper tubes/paper towel tubes. Make a few of these up before you go to the problem area. Hide them in protected areas around the campsite. Preferably under a rock or log so they don't get rained on. They won't help you this time. But when you go back there should be a reduction in ticks in the area.
