Varment Guard technicians use small live-catch traps. Traps are set in areas along pathways commonly used by the animals, most often around porches, decks, sheds, garages, patios, walkways, and concrete slabs. Although they may not reside and live on the property, chipmunks will utilize flower beds and other mulched areas to search for food. Traps are baited with a variety of attracting scents and baits likes peanut butter, apples, corn, sunflowers seed and bird seed.


Exclusion is the best method for keeping chipmunks out of buildings and should parallel rodent-proofing measures used for rat and mouse control. Essentially this involves the closure of all openings that might allow access to buildings along the foundation. Gaps, cracks, and holes should all be sealed. Any utility, phone, A/C, heat pump line penetrations must be sealed as well. Crawlspace vents should be screened with hardware cloth.

Chipmunks in urban settings often dig up and eat newly planted garden seeds and flower bulbs. Strawberries, plums, apples and other cultivated fruits are gnawed for their flesh or for their seeds. They commonly dig unsightly burrows in lawns and flower beds in which to nest. Costly damage may result when chipmunks excavate burrows along building foundations, beneath poured cement porches, patios and walkways. Gradual collapse of the excavations lead to the formation of stress cracks in cement slab construction, as well as inwardly sloped grade of pavement, a condition conducive to moisture drainage and retention along the foundation. Furthermore, chipmunks will nest beneath residences, sometimes gaining access to living spaces, basements and crawlspaces through utility penetrations and other structural gaps. Occasionally they take up residence in attics or other sites that are a distance above ground.

Frequently Asked Questions:

What do Chipmunks Want?

Chipmunks are always on the look-out for two things: food and shelter. They spend spring and summer stockpiling nuts, berries, seeds, and other foods. When they’re not stockpiling, chipmunks are looking for sheltered, hidden places where they can spend the winter with their food. Read more about chipmunks!

How Did That Chipmunk Get in my House?

Chipmunks may end up in your home while they’re foraging for food. They may accidentally squeeze or fall through gaps in window frames or the foundation, dash through screen doors or even dig into your crawl space. Do you have chipmunks in your home? Learn more about how they got there!

How Can I Keep Chipmunks Out of my Downspouts?

Clear your yard around the downspout as much as possible. Next, make a makeshift vent or filter for your downspouts. However, the best way to keep chipmunks away from your downspout is to keep them away from your home altogether To do so, keep your grass, bushes, plants, and trees well-trimmed. Learn more!

Do Chipmunks Hibernate?

Chipmunks cannot truly hibernate. Instead, they enter a hibernation-like state of suspended activity called torpor. During this time, their body temperatures and heartbeats decrease and they remain motionless to preserve energy. Torpor is not considered true hibernation, however, because they need to wake from torpor every few days to eat. Learn more about chipmunks and torpor!
