I agree with bama john , but it's hard to get a kid to eat anything like that

the best repelant I've found is Permanone Repel , it's not to be applied to your person, but it's a cloth's teatment. Infact I just orderd a new can , I did a goggle search to find it and ordered it , it is alittle pricey but works. I'll have to say I can't take credit for finding this product , Cuz turned me on to it , and we've just it for several years, the 6oz can he gave me lasted maybe 3 years , I spray it on my boots around the ankle & on my chaps mid knee ,claims to last for 2 weeks or so & I belive it does. I ran out last summer and failed to get more , I've already dug 2 deer tick out of myself this spring , 1 which left a big red spot a ring , just went to the doctor Thursday , doc is doing a Lymes test and put me on a high dosage of anabotics just in case. Should have the blood work back Monday. Try it , it's good stuff
