Dead animal in pipe

[plowhog]

Two marmots took up residence behind my rear barn. That's bad news since they will burrow under foundations, etc. Plus multiply.

The other day, they ran into a 8" irrigation drain pipe with only one opening. I sealed it off and trapped them in. I occasionally see them through a metal grate at the other end, but they mostly stay somewhere inside the pipe. I would like to humanely kill them, but trying to do that is too risky that they would escape. They have been in there about 6 days now.

Once they finally die, how can I get them out of the pipe? I don't have enough water flow or pressure in that area to flush them out. A garden hose would be inadequate as they are probably 10lbs +. The pipe is about 130 feet long, so a 100ft plumber snake wont work.

Any ideas?

Drown them?

130' plumber snake?

Actually a 100' snake would work if they didn't die in the last 30'.

If the entry way is capped, filling with water should drown them assuming the grate is on the high side.

throw some food inside with rat poisoning in it. Better than them starving to death. use a string with plastic bag tied to it and suck it through with a vacuum then possibly use a kayak anchor to drag them out?

Thats a good idea with the rat poison. Not sure if I can get a vacuum in a 100ft 8" pipe-- maybe a shop vac would pull enough?

A shop vac is what I meant. I use this method to pull wire through long conduit runs.

Put a T fitting on the end of your 8" pipe with a #160 body grip trap in each opening of the T fitting. You will get them both. Make sure you don't have critters around that would get in them. They will kill anything that sticks a head in them. You will need to use sticks to hold the trap in place.

Might even be able to get away with a #110

My neighbor put a grip trap outside his fence and gate very near where irrigation water drains off between our two properties. I was cleaning the ditch and almost stepped on the trap ... yikes.

You could put a live trap at the entrance to the pipe. Box around it with cinder blocks or plywood so it's the only way out. They'll run through the trap and you'll get at least one of them. Then dispatch humanely. NO chance of killing the wrong critter and better than letting them starve to death and get stuck in the pipe. Good luck.

Why get them out? Their bodies will decompose and weigh almost nothing. When enough water builds up in the pipe, the remains will be washed out.
