I got some bites on my hands and feet from walking and sitting in dead grass at night and I live in Texas. From the internet descriptions, I think my bites are also from wolf spiders. Awesome little creatures, but they cannot tell us from the bugs they are hunting. The mother spiders carry their babies on their backs for awhile, like opossums and scorpions do, and also, they hunt nocturnally. Anyway, they are worse than mosquito bites, because half of the top of my foot was swollen and itching so bad I could hardly study. So I put a green tea bag (only kind I have right now) in boiling water for a minute, then put it, still hot, on my foot. It felt SO good! And the itching stopped right away. Tea leaves are pretty amazing.
I was bitten by a "wolf" spider. My hand was was swollen twice it's normal size. A friend suggested a wet tea bag. The tea bag, when place over the bite, pulled the poison out of my hand within a couple of hours. No bad effects from the bite.
It seems regular tea bags will pull the poison out of spider bites, an abscessed tooth or any place where poison is causing swelling.
