Why Are There Marmots in the Yard?

Marmots, the largest members of the squirrel family, are found in 14 varieties across the nation. In western states, the biggest problem is the yellow-bellied marmot, or rockchuck, which enjoys hanging out in yards at high elevations and digging tunnels under large rocks, houses, and other protected areas. Their eastern relatives, called groundhogs or woodchucks, are much less picky about their burrowing sites. They may tunnel throughout lawns that offer food sources such as garden vegetables or any tender, green plants.

Marmot Lawn Damage

Unlike rabbits, deer, and other wildlife that graze in gardens, marmots in yards often strip entire vegetable gardens after only a few nights. Other pests tend to eat more slowly or selectively and don't mow stems down to the ground like marmots do. The pests' digging habits can also leave behind mounds of excavated dirt, which interfere with mowing or gardening and damage equipment. On occasion, tunnels built under buildings weaken foundations.

Getting Rid of Marmots in the Yard

Marmot fencing is the longest-lasting solution to infestations, but not always the most efficient. Fences need to be made of heavy wire, stand at least three feet high, and be buried about twelve inches underground, with the lower six inches bent into an L-shape. Using this method on an entire lawn is time-consuming and disruptive to landscaping, so it's best for small areas only. A marmot in the yard may also be repelled by frightening devices or more permanently removed with fumigants and traps. The experts at Critter Control can help each property owner determine a personalized method to deal with marmots.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
