What is this bite alert and how dose it work ?

hi Richard.
Brown recluse spider bite The pain associated with a brown recluse spider bite typically increases during the first eight hours after the bite. You may also have fever, chills and body aches. The bite usually heals on its own in about a week. In a minority of cases, the skin at the center of the bite can become dark blue or purple and then evolve into a deep open sore (ulcer) that enlarges as the surrounding skin dies. The ulcer usually stops growing within 10 days after the bite, but full healing can take months.
Seek prompt medical care in the following situations:

• You are unsure whether the bite was from a poisonous spider.
• The person who was bitten experiences severe pain, abdominal cramping or a growing ulcer at the bite site.
• The person who was bitten is having problems breathing.

Your doctor may recommend a tetanus booster shot if you haven't had one in the last five years.

Doctor ER quickly as any spider bite is going to liquefy flesh and cause infection and depending on the spider other problems as well

A topical salve might work. Some people are more sensitive to bed bug bites than others. I am one myself, so I have been combatting them for awhile, and believe I have the upper hand.. There is lots of research available on the internet on how to get rid of them. You could also google what product might be best for bites.
You get the stinging sensation about 5 or ten minutes after they have bitten, and within a few minutes more a red welt develops. I have found the less you scratch the bite, the better. In about 45 minutes to an hour the itching starts to subside.
Of all the products I have tried (not that many but a few), the most effective is a spray from Harris. It is in yellow bottles or spray cans. Try Home Best or Walmart for it. It is rather expensive, about 10 or 11 dollars a can, but very effective at killing bugs.
Anyway I hope you find something to help with the bites.

Not people but they can damage clothes.

Could be about to fail. The point where the clutch "bites or grabs" is normally half way from floor to top position.

since any part is over 600 bucks to replace you will need to get it diagnosed correctly. Our guessing is only that. guessing.
