Did you know that crews have refused to harvest crops because of the overabundance of dangerous ground squirrel holes? In one walnut orchard, the owner was told that the harvesting company couldn't bring in their shakers because they could be damaged due to the numerous holes. Another thing to worry about is someone getting injured because holes and ladders don't mix.
Ignoring a ground squirrel over-population in an orchard is not a good idea. Eventually the little munchers will destroy trees and affect the orchard's yields. Ranchers seem to take action about the same time they are tripping over holes and stressing over the income that is being devoured by the destructive rodents.
Often times, baits are the first choice in getting rid of ground squirrels. (I'll save for another blog, the dangers of using poisons and why it is best to find a green solution.) Even if the baits kill the ground squirrels, the orchard is still left with dangerous holes that are ready for the next ground squirrels to call home. The destruction of the orchard will continue.
