    Hello
    Moth balls and Repel All work if they are not hibernating. Typically they start hibernating late October or November when it gets cold!
    Under the shed is not a free shelter to all the homeless wayward chipmunks in the neighborhood! The first year the moved some stones in the back of the shed to create a small entrance so a few could sneak in! Last year they moved a lot more stones to create a larger side entrance for all their rodent buddies and pals!! No big holes for ground hogs or squirrels just chipmunks that can get through very small spaces!!
    Basically I pryed off the composite trim bottom board. Pull out the nails. Cut the hardware cloth to make 4 - 118” long pieces.
    Staple it up and screw the trim board back with deck screws which will hold better over the screen mesh.
    Note: Front composite board only that goes under the ramp.
    I had to cut it on the front of the shed with a sawzall because it went under the ramp. Then after the hardware cloth went up, I had to grind the edge of the front composite trim so it would fit back up with the screen going in between on each side of the ramp.

    Aluminum flashing or Hardware Cloth can be used but Hardware Cloth still lets air circulate.

    I really hope this works for you. Pests can be so determined to be where you don't want them.

    Looks like a good job. I have had good luck with the 1/4" hardware cloth doing much like did here. Now I need to figure out how to keep the woodpeckers from making holes in the T111 on the shed.

    I have given up on trying to put up rodent barriers for the house and under the sheds. Instead, I bought a few bottles of mint oil off of Amazon and sprayed the stuff all over the place. Rodents hate mint.

    Mint sounds good but I talked to a few people and they had good luck with the right hardware cloth. It is tricky and here is more info from google AI

    Do chipmunks and squirrels chew thru chicken wire?
    Yes, both
    chipmunks and squirrels can chew through chicken wire, and it is not an effective barrier for keeping them out of a garden or chicken coop. Chicken wire is too thin and flexible for a determined squirrel or chipmunk, and its large hexagonal openings allow chipmunks to squeeze through without even needing to chew.
    Why chicken wire fails
    • Too flimsy: Squirrels and other rodents can easily chew through the thin wire strands. They are also known to chew through other materials like plastic and wood.
    • Holes are too big: The large holes in standard chicken wire allow small animals like chipmunks to simply pass through without chewing at all.
    • Burrowing: Even if you secure the sides, chipmunks and ground squirrels are experts at burrowing underneath fences and barriers to gain entry.
    A secure alternative: Hardware cloth
    To effectively protect a coop or garden, use hardware cloth instead of chicken wire. Hardware cloth is a thicker, stronger, and more secure wire mesh with a smaller opening size.

    Recommendations for use

    • Mesh size: Use hardware cloth with a maximum mesh size of 1/2-inch to 1/4-inch to prevent chipmunks and squirrels from getting through.
    • Gauge: For especially persistent rodents, use a heavier gauge wire, such as 19-gauge or 16-gauge.
    • Install underground: To stop burrowing pests, bury hardware cloth around the perimeter of the coop or garden, extending it at least 6 to 12 inches underground.
