Document Description
Reduce and control the ground squirrel population around the historic Vallejo Home and surrounding core area at Sonoma State Historic Park to protect cultural resources and reduce damage to the buildings and landscape. Control methods have been selected that avoid the use of baits and poisons. Work will utilize a combination of the following methods over time: • Utilize enclosed exterior trap boxes and CO2 traps positioned strategically around the property by a licensed pest control company to trap squirrels; • Treat squirrel tunnels with carbon monoxide. • Backfill squirrel tunnels with a slurry of dirt and organic material from existing squirrel mounds near the tunnels; and • Utilize a tractor to rip the soil up to a depth of 20 inches in certain locations to destroy squirrel tunnels.
