Color: The eastern chipmunk is a small, brownish, ground-dwelling squirrel. It has two tan and five blackish longitudinal stripes on its back, and two tan and two brownish stripes on each side of its face. The longitudinal stripes end at the reddish rump. The tail is 3 to 4 inches (8 to 10 cm) long and hairy, but it is not bushy.
Size: 5 to 6 inches (13 to 15 cm) long and weighs about 3 ounces (90 g).
The burrows of chipmunks often are well-hidden near buildings (such as basements and garages), gardens, stumps, woodpiles or brush piles.
Chipmunks are diurnal. They are industrious creatures who spend their days gathering and storing food in their burrows. The food stored in their burrow will sustain them during the winter. Chipmunks possess cheek pouches in which they store food before depositing it in their burrow. Researchers have reported watching a chipmunk stuff nearly six dozen black-oil sunflower seeds in its pouches.
When chipmunks are present in large numbers they can cause structural damage by burrowing under patios, stairs, retention walls, or foundations. They may also consume flower bulbs, seeds, or seedlings, as well as bird seed, grass seed, and pet food that is not stored in rodent-proof storage containers.
Cultural Methods and Habitat Modifications
Landscaping features, such as ground cover, trees, and shrubs, should not be planted in continuous fashion connecting wooded areas with the foundations of homes. They provide protection for chipmunks that may attempt to gain access into the home. It is also difficult to detect chipmunk burrows that are adjacent to foundations when wood piles, debris, or plantings of ground cover provide above-ground protection.
Place bird feeders at least 15 to 30 feet (5 to 10 m) away from buildings so spilled bird seed does not attract and support chipmunks near them.
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.
Hardware cloth may also be used to exclude chipmunks from flower beds. Seeds and bulbs can be covered by 1/4-inch (0.6-cm) hardware cloth and the cloth itself should be covered with soil. The cloth should extend at least 1 foot (30 cm) past each margin of the planting. Exclusion is less expensive in the long run than trapping, where high populations of chipmunks exist.
Trapping is the most practical method of eliminating chipmunks in most home situations. Live-catch wire-mesh traps or common rat snap traps can be used to catch chipmunks. Common live-trap models include the Tomahawk (Nos. 102, 201) and Havahart (Nos. 0745, 1020, 1025) traps.
A variety of baits can be used to lure chipmunks into live traps, including peanut butter, nutmeats, pumpkin or sunflower seeds, raisins, prune slices, or common breakfast cereal grains. Place the trap along the pathways where chipmunks have been seen frequently. The trap should be securely placed so there is no movement of the trap prematurely when the animal enters. Trap movement may prematurely set off the trap and scare the chipmunk away. A helpful tip is to “prebait” the trap for 2 to 3 days by wiring the trap doors open. This will condition the chipmunk to associate the new metal object in its territory with the new free food source. Set the trap after the chipmunk is actively feeding on the bait in and around the trap.
Check traps frequently to remove captured chipmunks and release any nontarget animals caught in them. Avoid direct contact with trapped chipmunks. Transport and release live trapped chipmunks several miles from the point of capture (in areas where they will not bother someone else), or euthanize by placing in a carbon dioxide chamber.
Common rat snap traps can be used to kill chipmunks if these traps are isolated from children, pets, or wildlife. They can be set in the same manner as live traps but hard baits should be tied to the trap trigger. Pre bait snap traps by not setting the trap until the animal has been conditioned to take the bait without disturbance for 2 to 3 days. Small amounts of extra bait may be placed around the traps to make them more attractive. Set the snap traps perpendicular to the chipmunk’s pathway or in pairs along travel routes with the triggers facing away from each other. Set the trigger arm so that the trigger is sensitive and easily sprung.
> To avoid killing songbirds in rat snap traps, it is advisable to place the traps under a small box with openings that allow only chipmunk’s access to the baited trap. The box must allow enough clearance so the trap operates properly. Conceal snap traps that are set against structures by leaning boards over them. Small amounts of bait can be placed at the openings as an attractant.
MANUFACTURER RECOMMENDED PRODUCTS AND TREATMENT FOR Chipmunks CONTROL
Pests need food, water, and shelter. Often the problem may be solved just by removing these key items. Before even thinking about chemical pest control, it is important to be aware of Pest’s Conducive conditions & It’s Recommendations.
Pesticides can be purchased in many different forms, each form has specific uses and application methods The pesticide application method you choose depends on the nature and habits of the target pest, the properties of the pesticide, the suitability of the application equipment, and the cost and efficiency of alternative methods. Your choice is often predetermined by one or more of these factors. Follow label directions for volume recommendations and application rates based on the pest to be controlled and utilize appropriate application tips on equipment. , these application methods are for informational purposes only.
