YARNELL, Ariz. -- Arizona resident Chuck Kristensen makes a living tracking down creepy crawlers that most people try to avoid.

For 30 years, he’s scoured the hills of Yarnell, located about two hours northwest of Phoenix.

Kristensen is looking for scorpions and spiders, anything with venom.

“I can actually milk the venom and sell it to medical research companies,” he said.

Here’s how it works: Kristensen picks up the critters either with tweezers or his bare hands, and places a capillary tube on their stingers or fangs. He then gives the scorpion or spider a small shock to stimulate the venom release into the tube.

According to Kristensen, it can be an extremely tedious process.

“Sometimes we have to milk 10,000 spiders just to get enough venom for one order,” he said.

The research derived from this type of venom milking has already proven valuable to the field of medicine. Kristensen said some of the tarantulas he works with have toxins that can stop a heart attack.

“That makes me feel good when I hear that. I love this job. It’s a fantastic job,” he said.
