Are these something that pets/humans can catch from the pond water (I've been putting my arm in there with minor cuts/scrapes and I'm now having a minor anxiety meltdown)? Will the fish (fancy guppies) in the pond carry them? If so, how do I treat the fish? Can/should I kill them in the pond water itself? If so, how? There were three (that I found/removed) in my foam media filter pad in the box filter in the bottom of the pond. From Googling, I *think* they are Horsehair worms, and come from crickets, which I have pulled out of the pond when skimming. If so, I think they are harmless, but still, I have a minor phobia and really would prefer they not be in there at all, so what chemicals can I use in the water that will kill them and ABSOLUTELY NOT harm the neighbor's cats who drink from the pond? Also, I need to know if I can be infected as if so I need to reach out to my healthcare provider for treatment, and if cats can be infected as if so I need to inform my neighbor that his cats need treatment. What a mess! Help!
