Can horsehair worms be killed or exterminated by spraying them with vinegar?

Expert Response
While horsehair worms are a bit unsettling to look at for most, they are harmless to people, pets and plants. We do not recommend exterminating them with vinegar. They should be considered beneficial because they can be effective in controlling certain insects.

I'm sorry, I misunderstood that they were located inside your home. In that case, it makes perfect sense as to why they are unwelcomed guest. In short, I cannot find any research or recommendations that vinegar will kill horsehair worms. May I ask where you are finding them inside your home? They require water in order to reproduce. I'm curious to know if these are coming inside seeking water or if you might have an insect in or near your home that they are coming from. There may need to be a bit of investigation as to why they are inside your home.
