Marmots on pool deck

Hi there: We have moved into a new house and have just discovered that we have a serious marmot problem. We have seen them in our yard and not been concerned, but now we have discovered that our lower deck – and it is a large one surrounding a pool – is absolutely covered in poop droppings, so many droppings that you cannot walk freely on the deck. We have lots of grandchildren who live locally and will be coming here many times during the summer, I see that marmots can carry ticks that lead to Lyme Disease. We know all about that problem as we have a granddaughter from Kelowna who we have had to send to the States to be treated for Lyme Disease which she contracted here in BC, and so are really concerned about this problem. I see I can buy a Blackbox Gopher Trap that will trap and kill gophers – will it work for marmots?? And I can buy an animal cgge trap that will trap marmots but not kill. How do I kill the marmots that I catch in the cage?? Where do I get whatever you recommend? Thanks for your advice. Trevor , Lake Country, B.C.

Trapping in a live trap or kill trap is probably your best solution.  Gopher traps may be too small.   If you use live traps you will need a permit to transport wildlife to a new location.   It is difficult to attract marmots into a trap so you would have to place them along their normal travel paths.   On Vancouver Island Marmots were almost extinct so I believe they are now a protected species.   Some control suggestions here:  http://www.wildlife-removal.com/marmot.html
