Meh, just pull them off when you notice them. The tick has to be on for quite some time to transmit Lyme disease. Just make sure to check your kids after they play outside.
That's what I do; just pull them off. But he "quite some time" is'nt as long as some people think ~36 hours they say
We try to check the kids every day, but sometimes forget... or you miss one or they are on the couch from the dog or falling off your clothes and then climb on you or or etc...each of my kids has already had one that was biting them this year (not just crawling). I've had 3 so far and my wife has had 1.
Between construction work, my yard maintenance/playing, and hiking/mtn biking I pull a good 20+ a year off me. I have been precautiously treated twice (when the bites developed the tell tale bulls-eye pattern) for Lymes though never actually had it show up in my blood stream (thank goodness)
I've never heard of this clothes treating, may look into it. Though it seems they usually either climb up from the bottom or just fall on you from the trees. Way too hot (for me) to not wear shorts and short sleeves so lots of skin exposure too. I've tried dousing my legs/feet/shorts with Deet before Mtn biking but it's a pain and kind of sticky/smelly. Nay try again though as this year they do seem worse already and it's only Spring!
They are pretty damn annoying
