Basic snare question

[GSP x2]

I have a basic question for you guys. I just started snaring about a week or two ago. I have my set on good runs or in my opion good runs. I have cought some coons and the coyote I put a picture of on another thread. I have been dispatching the animals with a 22 in the mellon. There has been a smalll pool of were the animal dies. To my question, does this blood keep critters from using that spot again? The reason I ask is that I might have two crossing in the same fence 20yrds a part. One has had a fresh kill and no other signs of animals using that for days while the other run will catch another animal and show more sign of use. Hope you get what I am trying to say. Is there anything I should be doing after a catch to keep animals using that same run?
Thanks Guys
