Did you know that those blue-belly lizards, otherwise known as Western Fence Lizards, have a protein in their blood that deactivates Lyme disease? When the ticks are very small their main food source is our cute little blue belly lizard. When the baby tick bites the blue belly they get a dose of the protein from the blue belly's blood and if the tick had the lyme-causing bacteria, then they will no longer be carriers of that disease! We have lots of blue bellies out at our place and every time I see one I am so grateful for them. Here are a couple links to sites that talk about this in more scientific terms if you are interested:

We have a lot of ticks and I'm always afraid that the kids will be bitten by one that has a disease. Every day we check for ticks before taking a shower, but it seems that the longer we live here, the less likely we are to be bitten. I've noticed this with my horses, too. The horse we brought up here with us, Snippy, was plagued by ticks the first year here. The horse we bought from our neighbor didn't seem to get so many. This year, Snippy only got about as many as the native horse, so maybe we also are building a deterrent-smell or taste to them too, lol.
