ok... from what I understand, its just best to get the tick OFF. The toxic stuff is actually in the tick's body not just its "mouth" so if you just pull it off when you see it you'll be better off than messing around trying to get it to "back out" or whatever those tricks are supposed to do. If the ticks head or beak stays there you can try to get it out if you can, otherwise it will come out on its own like a sliver. My kids have had a couple ticks already this year and more often than not the whole tick comes out.
My "technique" is to do it quickly. I have a pair of wide tweezers and in an all at once movement I just slide the bottom side of the tweezers under the tick (as close to the head as I can get)and "grab & go"! I think if you mess with the tick too much it will dig itself in.
I do the same with my dog...although we use frontline on him and he has very few he usually ends up with them near his eyes if he does get one. Hubby has to help with that to hold the dog.
For my horses is just use a flyspray that works on ticks too...then pull 'em when we see them.
Dr. OZ on Oprah was who I got my info from as far as pulling ticks.
Oh...yeah, We use regular bug spray on us humans. What ever brand I have on hand. I don't know that one works better than another. I like the stuff that goes on dry tho...I think its "off" not sure tho... Orange spray can.
Be strong and courageous, and do the work. Don't be afraid or discouraged by the size of the task, for the Lord God, my God, is with you. He will not fail you or forsake you.
