I use chicken wire instead of construction fabric. Also, available at sporting goods stores coyote urine is used out west to deter rodents from chewing vehicle wires. Then there is hot pepper powder & onion/garlic/allium concoctions that is applied routinely.

Build some frames to go around your seedlings until they are big enough to not be a problem.

Big thing of cheapest chili powder from Costco or Job Lot, sprinkled liberally around everything you want to save...repeat after rain/watering.

I'm reminded of my neighbour 30+ years ago who had a lroblem with Australian lossums eating a climbing plant he wanted to cover the front of the house up over the first floor balcony. Having bee an electricity line supply worker onthe 40,000 volt lines most of his working life he ran two copper wires along the top side edges of the balcony rail. The wires were connected into a standard plug & plugged in. All went well til one morning he left his bed & walked onto the balcony stretching his arms ul andback whilst he admired the beautiful scene & sunshiny day. Reaching the railing he brought his arms forward & placed his palms onthe top rail to leanon it. Needess to say he never plugged the possjmdeterent again. (Note Australian electricity is supplied at 50hz 240 volts on minimum 10 amp supply lines.
Oh yes. Roy lived.

I have no idea, but I truly considered keeling my dog tied by my pecan tree for the day and see if I solved two issues: squirrels and get her some exercise.

FrostyJim from Wasilla Alaska uses a wire frame to prevent moose dining.

I do not kill wildlife that do what is normal for them. Humans enter nature seeking to dominate & control. Place construction fabric over your plantings. Flat or as a cubicle cage. Use your intelligence to out wit the reforesters of the world. Plant what squirrels will not see as food. Come on. Haven't we learned anything about killing as a solution? Move to a condo if you can not get along with nature. Killing wildlife that is only doing what is natural is disturbing. We move into their world, expect them to resist what is forage & resent them for their natural behavior. Adapt to them or become frustrated. Poison? Are you serious? =0{

A good pellet gun . I used to use a 22 cal rifle with subsonic ammo , but that was in the 60s you might get in trouble nowadays . Hang the dead squirrel where other squirrels will see it , and repeat they will get the message . I just let them be now , let the dogs and cat take care of it , live and let live

Cats ? Humm , first and only answer , but no double points .

Not really much you can do, they are rats with fuzzy tails that will destroy pretty much anything they get near,
