3 Reasons Your Ground Squirrel Control Isn't Working

Getting rid of ground squirrel infestations can be challenging. From researching the best control methods to purchasing and implementing - there's room for error.

1 - Rodent Misidentification

For example, if you put up an owl box thinking it will eliminate ground squirrel or prairie dog problems, you will be disappointed. 
  • Ground Squirrels & Prairie Dogs are diurnal - most active during the day.
  • Gophers are nocturnal - most active at night.
  • Owl boxes are a good solution for gophers and mice because they attract owls and owls hunt at night when the gophers and mice are out.

2.  Didn't Follow Instructions

It's the middle of a hot summer day and you correctly identified the rodent pests as ground squirrels. You activated a gas cartridge and tossed it in one of their holes, covered it with dirt, and walked away assuming the problem is solved. 

Checked back a few hours later...

The Result:

  • Gas cartridges are not the best solution on a hot summer day. The gas can dissipate through the dry soil, diluting the concentration and making it ineffective.
  • Covering only one hole of the ground squirrels' burrow system, allows the gas to escape and allows place for the ground squirrel to avoid the gas.
  • For best results, follow the gas cartridge instructions and review:  University California - Ground Squirrel Best Management Practices - Fumigation


3.  No Follow-up Treatments  

You correctly identified the burrowing rodents as ground squirrels, and properly used a recognized control method, one time. 

One time of doing almost anything and anticipating perfect results, is considered fairly unrealistic. What if the ground squirrels were visiting a neighboring field or maybe even having lunch on a tire?

  • For best results, reapply the treatment as directed by the operating instructions or label.
  • Observe the surrounding area. If the neighboring properties have ground squirrel over-populations, expect continued follow-up treatments to control the re-infestation.
  • Pay attention to the ground squirrels' environment. At times, they live in one area and feed in another. If they are living on the other side of the fence, coordinate ground squirrel control with the neighbor.
A quick summary - pay attention, follow instructions, be aware of environmental factors, follow-up treatments are key, and adapt as needed.

Let me know if there's anything you'd add or if you have questions.

The Best Way to Fill a Ground Squirrel Hole

Ground squirrel holes! They can destroy beautiful landscaping and make athletic fields and pastures hazardous. Ground squirrel holes are much more than an unsightly nuisance, they can cause serious injuries. How do you get rid of ground squirrel holes?  Often people grab a shovel and start pushing the dirt surrounding the hole back in. That's usually not enough dirt on the outside, so they get more dirt and keep shoveling it in until it looks full. Surprise! The next day the hole is back. After trying dirt, rocks are often the next choice. Again, the next day, the hole is often back.  Why doesn't filling in ground squirrel holes using a shovel work? Shoveling in the holes is often unsuccessful, because the ground squirrel is hiding in a lower portion of the tunnel system and they dig their way out. What is the best way to fill ground squirrel holes? The Burrow Blocker machine is a fast, easy, and effective way of filling in ground squirrel holes.The patented mac

Is it a Ground Squirrel or a Gopher?

Do you know the difference between a Gr ound Squirrel and a Gopher ? If you are battling burrowing rodents on your property, after awhile you might just start channeling Carl Spackler, Bill Murray's character in the movie, Caddyshack. Remember when Sandy McFiddish, the head groundskeeper of the golf course told Carl, in his rich Scottish accent, "Carl, I want you to kill all the golfers on the golf course."? Carl replied, " Correct me if I'm wrong Sandy, but if I kill all the golfers they'll lock me up and throw away the key." Sandy yelled, " Not golfers, you great fool! Gophers, rodents! THE LITTLE BROWN, FURRY THINGS!" Carl replied, "We can do that. We don't even need a reason." Remember that destructive dancing gopher in Caddyshack? (Be patient...it has a long intro.)     Most of the people that visit this blog, do have a reason. They want those destructive diggers to just stop destroying

Home Remedies for Ground Squirrels

People like to share with me their "Do It Yourself" Remedies for Ground Squirrels. Here are a few that I've recently heard. I can't guarantee if they work, but they're at least creative! Home Remedies for Ground Squirrels & Prairie Dogs GUM - Not ordinary gum, but Bazooka Bubble Gum. You know, the hard squares of gum that as a kid almost broke your jaw on the first bite?  Once a week, this guy's neighbor puts 1 square of Bazooka gum in every ground squirrel hole on his property. He has almost 100 holes, so I doubt if he takes the time to read the comics wrapping each gum square. The neighbor says it works well at eliminating the young ones because they can't digest the gum. According to an expert, Jim Knight, a Montana State Extension Wildlife Specialist . "Bubble gum might sometimes clog a ground squirrel's intestines or burst its stomach, but no one has conducted scientific studies on its overall effectiveness. It's hardl
