Chipmunks (aka ground squirrels) can be a pest and sometimes will need to be removed to prevent property damage to a home.
Chipmunks in walls can chew wires. This is one good reason that chipmunks should be kept under control. Many times chipmunks will chew the bottom of the siding of a home and get up into the walls of a home also.
When basic deterrents and exclusion methods fail, Grade A Critter can step in to save the day. Simply waiting for chipmunks to leave is a mistake that only allows infestations to escalate. Be proactive and trust our trained technicians to remove chipmunks as quickly and humanely as possible.
Eastern chipmunks typically inhabit mature woodlands and woodlot edges, but they also inhabit areas in and around suburban and rural homes.
Adult least chipmunks mate over a period of 4 to 6 weeks from April to mid-July. Least chipmunks produce 1 litter of 2 to 7 young in May or June. Occasionally a second litter is produced in the fall.
Chipmunk pups appear above ground when they are 4 to 6 weeks old — 2/3 the size of an adult. Young will leave the burrow at 6 to 8 weeks. Population densities of chipmunks are typically 2 to 4 animals per acre (5 to 10/ha). Eastern chipmunk population densities may be as high as 10 animals per acre (24/ha), however, if sufficient food and cover are available. Home ranges often overlap among individuals.
Chipmunks should be excluded from buildings wherever possible. Use hardware cloth with 1/4-inch (0.6-cm) mesh, caulking, or other appropriate materials to close openings where they could gain entry.
Fumigants are generally ineffective because of the difficulty in locating the openings to chipmunk burrows and because of the complexity of burrows. Aluminum phosphide is a Restricted Use Pesticide that is registered in many states for the control of burrowing rodents. It is available in a tablet form, which when dropped into the burrow reacts with the moisture in the soil and generates toxic phosphine gas.
The majority of chipmunk damage involves minimal economic loss (under $200). Homeowners report that chipmunks are quite destructive when it comes to their burrowing activities around structures. This damage warrants an investment in control to protect structural integrity of stairs, patios, and foundations. Their consumption of seeds, flower bulbs, fruit, and vegetables is often a nuisance.
