Help with front & back decks

Maybe mothballs would keep them out.

Hey Bill try calling your local senior center and asking if they have anyone that can help you. Also if you have a landline there is usually a number you can call (I think 211) and they might have suggestions too. But if you decide to deal with it on your own check this link because I bet you have a groundhog http://www.wildlife-removal.com/groundhog-under.html

I have a groundhog living in my 3 sided structure that I scared accidentally one morning. And boy does he dig up the dirt and make a mess! I haven't had much luck catching him and actually got a possum when I tried to get him. Wildlife....sigh

Dig a trench about 12 inches deep along the opening and install 1/4- to 1/2-inch wire mesh or hardware cloth or strips of lattice. Make sure the material you choose is at least 12 inches wider than the area you want to cover. Bend the bottom 6 inches of wire mesh outward in an L-shape. This prevents animals from digging under your screen. Insert the mesh into the trench so the bend end is pointing outward. If you’re using lattice, bury the bottom edge at least 2 feet deep to ensure the animals can’t dig under it. Backfill the trench with soil and tamp it down to make sure the mesh is snug. Secure the top edge of the mesh to the underside of the structure, using nails or garden staples, which are U-shaped fasteners that are hammered into the wood. As a safety precaution, install a one-way door somewhere along the wire mesh. This allows trapped animals to leave, but prevents them from getting back in.

If you’d rather not dig, use patio blocks to cover the opening instead of burying the bottom edge. Cover the space with hardware cloth first, but instead of burying the bent edge, place patio blocks on top of it. Make sure there is a slight slope in the ground so that water runs away from the blocks. If excessive moisture is an issue beneath the deck, blocks may not allow enough air flow to dry the area beneath. Animals tend to avoid areas that are open and that have a lot of light, so remove walls, panels, lattice or plants that cover the area. By allowing light to flow through on all sides, you may encourage the animal to seek out a more secluded location.

have you tried humane baited traps

Yes I have in all 8 holes

Try applyimg castor bean oil or a garlic and rotten egg spray around you deck area and surrounding yard space.
