How about Armadillos they are night diggers and love bugs etc.

My Chihuahua doesn't dig. Possums dig in my yard - I think they are looking for grubs. Sometimes I'll catch a squirrel digging around newly planted plants - I think they like the roots, but they do that during the day.

My neighbors says its a cat. I didn't know they dug so much. He suggested fox urine. Does anyone have any experience with this or any other repellant to keep cats away.

Cats very nicely cover up the holes they dig. Even if it was a cat I don't think fox urine would keep them or any other critter away. It's more likely one of the animals mentioned above. Sorry, but I don't have any solutions to offer. Hopefully someone else will say what worked for them in a similar situation.

Have you tried cayenne pepper? You have to reapply if it rains, but this time of the year that's not as much of a problem. Cayenne pepper should keep dog or cat from digging. I've also used mothballs. they are pretty cheap and last a bit longer. I don't care for the smell myself, so I actually would use the cayenne pepper. but to each his (or her) own.

The small holes sounds like an armadillo. We get them all the time and they will make swiss cheese of your yard and garden beds. Yours sounds like a visitor. If one takes up residence under your house or porch, you'll find huge holes about 15' apart and the burrows will be very, very deep. After they give birth and totally wreck your yard, they will leave just as suddenly as they appeared and you won't have anything growing that will be able to recover from the devastation. You could try a humane trap and try to relocate the varmint. Fox urine won't deter a 'diller. I was never able to get rid of the ones that decided they liked my place, I just had to put up with them while they were living there.

I vote armadillo looking for grubs.

Cats hate the smell of citrus peels. Don't know if it would work for other critters. Go out with a flashlight at night and see if you see anything.

I have 3 digging weinner dogs, they are digging for moles. I just have to eleminate the moles. I sprayed beneficial nematoes to get rid of the grubs, so the moles would leave. Every week, I put less and less dirt down, so I think it just takes awhile for this to work. I only had to put down 1 bag of dirt this weekend to fill the holes the dogs dug. They are now digging on the states property where we did not spray nematoes. If it is an armadillo, you may want to get rid of your grubs. My little german dogs were bred to dig, I do not think the chihuahua is your problem, he was trained to bark. Barbra

Thank you guys for all the insightful advice. My neighbor swears he has seen the cat digging and that it looking for grubs, which would confirm seamommy's and justintx's suggestions; His flowers are still getting eaten up despite putting down fox urine and "critter ridder."

I suggested monitoring like fool4flowers suggested but my spouse thought i was insane when I asked if I could put the video camera in the yard. The strang thing is that that whatever is eating my garden is only affecting the flower bed, not the lawn.

Cats also like to dig in soft flower beds to use as litter box so be careful where you put your hand, lol. I found out the hard way and was really mad, lol. I go out at night with a flashlight to look at frogs and night blooming plants and sometimes spot things sneaking around I don't see during the day like snails and cut worms and I get rid of them as I find them. Thats how I caught the neighbors cat fishing in my pond too.

I highly doubt that it's a cat doing the digging. As Roselee mentioned, they're good about covering up the holes that they dig in what they use as a litter box. I don't think they'd dig for grubs, either, they're more hunt and chase feeders. BUT, raccoons and possums can look like cats in the dark, especially if you can't see the possum's tail! I think both will dig holes looking for grubs and they're nocturnal animals while cats are diurnal (mainly active at dusk and dawn).

In any case, if they're going after the grubs (which I've also found in my raised garden) then getting rid of the grubs sounds like the best plan.

Good luck!
