We have a suction tool, I think it’s literally called the bug bite thing or something. Basically it suctions on to your arm where the bite was and you pull your skin up into this tube and it sucks out the venom that causes the itching as well as the stinger if one was left behind.
My wife and I haven’t had a bug bite any time we’ve had that thing handy, so mainly we just put it on each other’s nipples for shits & gigs. I can’t really say that it’s effective, but it is fun.
You should just need to block the community. There’s a 🚫 symbol on the sidebar of a community, just click that and the posts should stop showing up on any of your feeds.
If you’re on mobile, the formating is kinda fucked so you’ll have to scroll to the bottom of the page to find it.
