Because bee stingers are mostly used against other insects. They don’t get stuck in a chitin exoskeleton, only in the more flexible skin tissue of mammals. In insects the barbs instead pull out soft tissue from inside, thus making them more lethal (to the bees victim).
And it keeps getting worse. Basically the whole base plus some forests and residential areas seem to be burning.
I think these are satellite measurements that accumulate over 24 hours though, so not sure if the image reflects the current situation well.
Link to the NASA map btw if anybody wants to check it out
