A commonly known nemesis of the soak seeker, the Red Spider Mite (RSM) inhabits a few natural hot springs. Barely visible to the naked eye, these tiny crimson mites scurry about on top of warm rocks and hot water in and around select hot springs throughout the Northwest.
The Red Spider Mite Effect
Red Spider Mites typically cling to the body (including clothing/towels in the proximity of the pools) and proceed to bite the skin in an unsuccessful attempt to lay eggs. The bites leave itchy red sores behind that usually heal completely after a couple of weeks. It is highly advisable to use itch relief cream and avoid scratching the bites. The human immune system kills off the eggs before they can hatch and eventually builds up enough immunity to kill off the mites themselves after a few days or so.
Note: Scratching bites during the first few days of proceeding contact with RSMs can result in additional bites. It seems that agitating the skin, in turn, agitates the RSMs.
Red Spider Mite Precautionary Measures
Keep your towel and gear far away from the hot springs pools and surrounding rocks. Hang your pack, clothes and towel off a tree limb and make a dash for it. At least this way they won’t be waiting for you on your towel and clothes post soak.
Use bug juice, ideally of the natural and lotion assortment, but only after your soak – no need to pollute the water with that junk. Plus, RSMs usually wait to dig in until their host has dry skin, applying bug juice after soaking should reduce your chances of receiving bites.
Red Spider Mite Treatment
Once bitten by RSMs (trust me, you’ll know), treatment involves copious amounts of anti-itch cream, as itching the bites early on can set recovery back significantly and may result in additional bites. Take it easy, sleep, stay hydrated, eat and don’t forget the itch cream!
