Habitat And Behavior Of Chipmunks

Chipmunks are small rodents that can be found all over North America. They typically grow to be around six inches long and have striped fur on their backs.

These animals usually make their homes in forests, fields, and gardens but live under porches or decks.

Chipmunks, sometimes called ground dwellers, are known for their quick movements and their ability to store food for the winter months. In general, chipmunks are active during the day and sleep at night.

They are omnivores, meaning they eat both plants and animals. Chipmunks feed on a variety of foods, including nuts, berries, seeds, insects, and small vertebrates like frogs or mice.

They use their sharp teeth to break open nuts or seeds that they have collected and store them in underground burrows or other hiding places. Chipmunks can cause significant damage to foundations due to their digging behavior.

To build chipmunk burrows or find food sources below ground level, chipmunks will dig tunnels that can create gaps beneath a foundation’s surface. These tunnels can collapse over time, causing the foundation to sag or shift in position.

Types Of Foundations Affected By Chipmunks

Chipmunks may appear harmless, but their unusual activities can significantly impact your home’s foundation. Understanding the types of house foundations affected by chipmunks is essential for homeowners.

Chipmunks And Their Effects On Different Foundation Types

  1. Poured Concrete Foundations: Chipmunks can cause damage to poured concrete foundations, which are common in many homes. Their burrowing activities can undermine the stability of the foundation, leading to cracks, shifts, and potential structural issues.
  2. Masonry Block Foundations: Chipmunks can also impact masonry block foundations, which consist of concrete block walls filled with mortar between them. Their burrowing can compromise the integrity of the mortar, weakening the foundation over time.
  3. Basements: Chipmunk active can lead to water intrusion from basement wall cracks. Active and previous pest activity should also be looked at when inspecting the basement for potential water damage.
  4. Soil Conditions: The type of soil around a property plays a significant role in chipmunk activity and the extent of damage it can cause. Soft soils, such as sandy or loose soils, make tunneling easier for chipmunks. These types of soils provide less resistance and facilitate their burrowing activities.
  5. Increased Risk: Homes built near sandy or loose soils are particularly vulnerable to chipmunk damage. The easy digging medium that sandy soils offer makes it more likely for chipmunks to establish burrows and cause severe damage to the foundation.

Signs And Symptoms Of Chipmunk Foundation Damage

It is important to know the signs and symptoms of chipmunk foundation damage to prevent significant structural issues from occurring.

3 Common Signs Of Chipmunk Activity Include:

  1. Cracks or Gaps: Check for cracks or gaps in walls or floors, particularly near the foundation. These can be signs of chipmunk burrowing, which compromises the stability of the structure.
  2. Uneven flooring: Be attentive to uneven flooring or areas that feel sloped or sunken. These can indicate underlying foundation damage caused by chipmunk activity.
  3. Sagging or Collapsing Foundations: Take note of foundation sagging or visible signs of collapse, such as sinking corners or bulging walls. Crafty chipmunks can contribute to such structural deterioration.

In addition to these visual cues, watch for the following signs that may indicate a chipmunk infestation:

  • Audible Activity: Listen for scratching or digging noises from behind walls or under floors, as chipmunks are active burrowers.
  • Feces Presence: Discovering chipmunk droppings around your home, particularly near entry points or nesting areas, strongly indicates their presence.
  • Burrow Holes: Keep an eye out for small burrow holes in lawns or near the foundation, typically with loose soil or evidence of recent digging. Chipmunks use these as entry points and for shelter.

If you notice any of these symptoms, it’s important to contact a professional as soon as possible. To address this, animal pest control companies may recommend measures such as installing chipmunk cages to mitigate the impact of their activities.

Effects Of Chipmunk Foundation Damage

Chipmunk-induced foundation damage can result in various structural issues that undermine the stability and safety of your home. Let’s explore the specific ramifications of chipmunk activity on your property’s structure.

Structural Issues Caused By Chipmunks

Chipmunks are notorious burrowers, and they can cause significant damage to building foundations with their digging. The tunnels that chipmunks create can stretch for several feet, creating spaces beneath foundations that can cause them to crack or shift.

This can lead to structural issues, including cracks in retention walls and floors, uneven flooring, and sagging or collapsing foundations.

One of the most common problems caused by chipmunk foundation damage is cracks in walls and floors. As the foundation shifts or becomes uneven due to chipmunk tunnels, it stresses the structure of the building above it.

This stress can cause cracks in exterior walls and floors that need to be repaired to prevent further damage. Uneven flooring is another common issue caused by chipmunk infestations.

If a foundation becomes uneven due to chipmunk tunnels, it can cause the flooring above it to become sloped or warped. This not only looks unsightly but can also make walking around the house both difficult and dangerous.

If left unchecked for too long, chipmunk tunnels can lead to sagging or collapsing foundations. If this happens, the structural integrity of a building is severely compromised and could result in costly repairs or even worse – a complete rebuild.

Health Risks Associated With Chipmunk Infestations

Not only do chipmunks cause structural issues when they burrow under foundations, but they also present health risks associated with their infestations.

One of the main concerns is the spread of disease as these creatures carry harmful bacteria and viruses such as Hantavirus pulmonary syndrome (HPS).

Additionally, due to their constant chewing habits, which help them keep their teeth sharp, these rodents leave droppings all over your property and urine that can be contaminated with harmful bacteria and diseases.

This can lead to various health problems, such as respiratory issues, allergies, and infections. Therefore, it is important to address any chipmunk infestation immediately to avoid further damage and protect the health of those living in the affected home.

The longer an infestation is left untreated, the more difficult it will be to eradicate and the greater potential for health risks associated with their presence in your home.

Prevention And Control Measures For Chipmunk Foundation Damage

Implementing preventive measures is crucial to safeguarding your property. One effective approach is using physical barriers to prevent chipmunks from gaining entry into foundations.

Physical Barriers To Prevent Entry Into Foundations

Chipmunks are small rodents that can fit through very small gaps in your foundation. Therefore, it is important to ensure that all gaps and holes in your foundation are filled with a durable material such as cement or expanding foam.

This will help to prevent chipmunks from entering your home through these openings and causing damage. Another effective way of preventing chipmunks from entering your home is by installing mesh screens or grates over vents or openings.

This will allow proper ventilation while preventing chipmunks from accessing your home. It is important to use a durable material for the screens or grates so that rodents cannot chew through them.

Trapping And Removal Techniques For Infested Areas

If you already have an infestation of chipmunks in your home, you can use several trapping and removal techniques to eliminate them.

One effective method is live trapping using humane traps baited with peanut butter or sunflower seeds. Once captured using these humane methods, the trapped chipmunk should be released at least five miles from your home, so it cannot return.

In addition, to live trapping, snap traps can also be effective when placed along the paths where the rodents frequently travel. However, caution must be taken when using chipmunk traps as they can cause harm to other animals if not placed properly.

It is important to note that prevention is always better than trying to control an existing infestation.

Regularly inspecting and maintaining your property, filling any cracks or gaps in foundations, and keeping food sources away from areas where chipmunks may be present can help prevent infestations before they occur.
