When you find a snake in your house remain calm and try not to disturb the snake, which will only drive it into hiding. To remove the snakes place piles of damp burlap bags, rags or towels in areas where the snakes have been seen.. After snakes have been attracted, remove the bags and snakes from the building. Sometimes it is possible to place and empty bucket, box or wastebasket slowly over a coiled snake. You may even be able to confine it to a corner with boards or other barriers. Trained professionals should remove poisonous snakes. Glue boards, such as used for mice or rats, can also be used to capture snakes. For larger snakes several glue boards can be placed on a larger piece of plywood or cardboard. A piece about 24"x16" would contain most large snakes in Montana. Once caught, the snake and board can be taken outside. The snake can be released unharmed by pouring vegetable oil on it (the oil counteracts the adhesive).
