Where Do Ground Squirrels Come From? - The Ground Squirrel Sex Talk

The Ground Squirrel Sex Talk
A Ground Squirrel Explosion?!! This is the time of year that we start getting desperate calls for help. It seems like overnight, orchards, fields, parks and yards are overrun with ground squirrels.

To better understand the situation we need to talk about sex...ground squirrel reproduction that is. Their mating system is officially called: polygynandrous. That means they are promiscuous litter critters that mate with up to 4 others. If you were wondering why you haven't seen them on their dates, it's because they copulate underground. 

When ground squirrels emerge from hibernation the first thing on their mind is sex. Is it surprising that the males emerge a few weeks earlier than the females? They just can't wait. This is their big chance because the females only produce one litter per year. (I've heard from a few biologists that they sometimes mate again if they lose their litter, but I can't find that in writing.)

In California, breeding season runs from December - April. The further south, the sooner the ground squirrels start breeding. After 25-30 days gestation, the female has a litter of 1-15. Yes, you read it right...up to 15 ground squirrels! Fortunately for us and the female, they usually have 7-8. Could you imagine caring for 15 little rodents underground? It's bad enough dealing with 8 of them above ground.

The reason we are seeing an overabundance of destructive diggers now? After 6 weeks of growing up in their burrow, the litters are emerging from their nests. The young look like miniature lighter colored versions of the adults. Guess what happens next? At about 6 months of age, the young ground squirrels will move into old abandoned burrows or scatter off to new territory. Ground squirrels have been known to travel up to 5 miles to start a new colony.

After they find the best location for their burrow, most ground squirrels will then get ready for hibernation. Then they get to repeat the cycle all over again. Let's just hope that it isn't repeating on your land. Oh, and I forgot to mention that ground squirrels live up to 6 years in the wild.

How To Get Rid of Ground Squirrel Holes

It looks simple. There is a ground squirrel hole. Just start shoveling dirt in it and soon the hole will be gone.  Some athletic fields are so riddled with dangerous holes, they bring in tons of dirt and use bobcats to fill the holes.  Surprise! Before the next day, most of the holes reappear! Fill it again and the same thing happens.  Those ground squirrels are persistent little diggers. Why doesn't filling in ground squirrel holes using a shovel work? Shoveling in the holes is often unsuccessful, because the hole is topped off with dirt. The ground squirrel is hiding in a lower portion of the tunnel system and they dig their way out as soon as you leave the area. 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 machine pumps a slurry of sand and water into the hole. The water is absorbed into the soil and all that remains is the sand. The b...

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 ...

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.
