Use sharp pruning shears to remove this year's fruiting canes, which will have done their job and will not live any longer. Cut them off all the way down to ground level. Removing these canes will help prevent diseases such as cane blight or spur blight from overwintering in the plants. Remove weak or broken canes, and thin remaining canes to about five or six per row foot. Thinning reduces competition and results in larger berries next year.
Deer are sometimes a problem in the fall.
Your best bet is to fence in plants you don't want nibbled. However, some gardeners have good luck deterring deer by hanging deodorant soap, still in the wrapper, in the plants or from posts or wire near plants. Place at least one bar near each small tree or shrub, or use several bars in large plants. The smellier the soap, the better. Rake up fallen leaves for use in composting food wastes.
