Every now and then comes a product that you can believe in and recommend to all your friends. This little gadget works like a champ and I have had them since backpacking days:

We currently have 3 of them - one for the house, one we keep in the camper first aid kit and Dottie the Dalmatian has one of her own. It seem poor Dottie gets ticks more than anybody around here and I just don't want to share medical equipment with the dog, ya know?
Get a couple of these. The web page also provides more info than you realy want to know about ticks. Nasty little buggers.
