if the hose is on the side of the house, go out the back door during the day, get it and spray them for a good 3 seconds. if they're still moving keep spraying, they'll die eventually.
You don't need to feel remorse, they are invasive.
so today something terrifying happened to me and I can hardly recover. so I was outside my house at 20:00 decorating the porch as normal because it was spooky season, and then something unexpected happens. so I'm placing the cobwebs in the bushes because the house has mums EVERYWHERE. so I alone was placing them and out comes the biggest hornet I've seen in my f**king life. so now I'm terrified out of my eyes and it does the most inconvenient thing and goes under the door meaning I can't escape. so at this point it's been a solid half an hour and my mom goes out to check and she opens the big door. in my house there's a small screen door in the front and a big wooden door in the back so I could peek out or whatever. so anyways my mom opens the big door and I instantly scream "NO THERE IS A HORNET ABOVE THE DOOR DO NOT OPEN IT" like any sane man so she says "well shit ok then bye." now I'm thinking well that almost got out of hand really fast but also I'm thinking well shit I'm cooked. then a BIGGER one comes over so now I'm really damn terrified and so I sit on the floor to think. and then I feel something on my head so I shake it off and then I think that it's a hornet and it's angry because I tried to shake it. now I'm crying for my life because I think there's a hornet on my head but there's nothing so I'm crying for a few more minutes and I realize there's nothing there. then I get up and walk to the other door but I see it's pitch black. luckily the bag with the cobwebs also has glowsticks for some reason so I use 2 but they do nothing. just so you know neither of the hornets have left. so I'm forced to use muscle memory of entering the house to get through the stone path, make the turn, do the lock with the help of those glowsticks and rush in.
