Common Bugs and Pests that Destroy Siding

Siding protects homes from the weather, provides insulation, and makes them look good. It shields the house’s structure and keeps its value. But, bugs and pests can mess up your siding, hurting its look and function. These intruders can cause serious damage to your home’s exterior. Knowing how pests affect siding helps protect your investment and keep your property in good shape.



Termites are destructive insects that can damage your siding if not controlled. They love cellulose-based materials like wood, making your siding a prime target. Knowing about termite infestations helps with early detection and effective pest management.

If you suspect termites munching on your siding, keep an eye out for some telltale signs. Look for mud tubes crawling along the foundation or walls, wood that sounds hollow when tapped, and wings left behind near windows or doors. Keep an eye out for sagging or warped siding, visible tunnels or galleries on the surface, and termite droppings (aka frass) as possible signs of termite activity.

To keep those pesky termites away from your siding, make sure the water doesn’t hang around your foundation by maintaining good drainage. Termites love moisture, so keeping things dry is a big deal. Also, don’t forget to give your siding a thorough check-up now and then. Seal up any cracks or gaps you find because those little critters can sneak in through those tiny openings.

If a termite infestation is already present, take immediate action. Consult with a professional pest control company experienced in termite management. They can assess the extent of the infestation and recommend appropriate treatment options.

Carpenter Ants

Carpenter ants are large, ranging from ¼ to ½ inch in length. These common bugs have segmented bodies, bent antennae, and are usually black or reddish-brown. Look for their presence indoors and outdoors, especially near wooden structures or trees, as they nest in moist, decaying wood.

Carpenter ants can cause damage to the siding. They dig tunnels and galleries within the wood to create their nests. Over time, it could weaken the structure of the siding, leading to sagging, cracking, or even complete collapse.

When it comes to dealing with those carpenter ants, you’ll need a well-rounded plan. First off, tackle any moisture problems in and around your home because these critters love damp wood. Fix up those water leaks, get better ventilation in crawlspaces and attics, and make sure water flows away from the foundation. Give your trees and shrubs a trim to create some space between them and the siding. That way, you’ll cut down on potential ant highways. Don’t forget to seal up any cracks or openings in your siding and foundation to keep those sneaky ants from getting in.

Getting the pros involved is a smart move when dealing with carpenter ants. These experts will come in and do a thorough inspection, finding those ant hideouts for you. They’ll then use specialized treatments like baiting, dusting, or applying liquid insecticides to target those pesky ants. Remember, regular monitoring and maintenance are key to keep those critters away and protect your siding from further damage. Let the professionals handle it, and you’ll have peace of mind knowing your home is in good hands.



Woodpeckers can become a nuisance and a potential threat to your siding. These birds are not part of common bugs. However, they naturally peck on wood surfaces, including your siding. Their pecking behavior can cause big damage over time, leading to holes, punctures, and ugly marks on your siding.

Indications of woodpecker activity on siding include distinctive round or rectangular holes ranging in size from small to several inches in diameter. You may also notice scattered wood chips or debris around the holes. Woodpeckers often create a repetitive pecking pattern, which can be heard as loud drumming noises on the siding.

Implementing strategies to deter woodpeckers can protect your siding.

  • Visual deterrents: Hang reflective objects, such as CDs, mylar balloons, or strips of aluminum foil, near the affected areas. The movement and reflection of light can frighten and discourage woodpeckers from approaching the siding.
  • Auditory deterrents: Use devices that produce loud noises or distress calls. These can include wind chimes, ultrasonic devices, or even recordings of woodpecker distress calls.
  • Physical barriers: Install bird netting or mesh over the siding to create a physical barrier that prevents woodpeckers from accessing the surface.
  • Repellents: Apply non-toxic taste or scent repellents to the siding. These repellents have an unpleasant taste or smell that discourages woodpeckers from pecking on the treated areas.

Mold and Mildew

When mold and mildew start taking over your siding, it’s not just an eyesore. These unwanted guests can actually pose health risks and cause damage to the siding itself. If you leave them unchecked, they’ll bring discoloration, staining, and even structural problems to the party. It’s best to deal with them promptly to keep your home looking good and avoid any potential harm.

Signs of mold and mildew growth on siding include black, green, or brown patches or streaks on the surface. You may also notice a musty odor coming out from the affected areas. If the siding feels damp or shows signs of decay, it could be a sign of a more serious mold or mildew infestation.

Preventing and treating mold and mildew on siding requires proper maintenance:

  • Regular cleaning: Clean your siding annually or as needed to remove dirt, debris, and organic matter that serves as a food source for mold and mildew. Use a mild detergent, water, a soft-bristle brush, or a pressure washer on a low setting.
  • Adequate ventilation: To keep too much moisture from building up, make sure there’s good airflow and ventilation around your home. Trim any vegetation near the siding to allow air to circulate freely. Also, address any ventilation or drainage problems that may be present.
  • Prompt repairs: Address leaks or water damage promptly, as these create ideal mold and mildew growth conditions. Inspect the siding for signs of deterioration and repair or replace any affected areas as necessary.
  • Application of mold-resistant coatings: Think about applying mold-resistant coatings or paints designed primarily for siding. These products contain additives that prevent mold and mildew growth, providing additional protection.


rodents and rats

Rats and mice can cause damage to siding as they seek shelter and build nests. These rodents are adept climbers and can easily access your home’s exterior, including the siding. Once inside, they may chew through the siding material, leaving holes, gnaw marks, and ugly damage.

Signs of a rodent infestation on the siding include the presence of droppings near the foundation or along the siding, chewed or gnawed areas on the siding, and greasy rub marks caused by their fur. You may also hear scratching or scurrying noises within the walls or observe rodents entering or exiting your home through gaps or openings in the siding.

Rodent-proofing your siding can prevent infestations and protect your home. Here are some practical ways to rodent-proof your siding:

  • Seal openings and gaps: Inspect your siding for any openings, cracks, or gaps and seal them with caulk or appropriate sealants. Attention areas where utilities enter the house, as rodents can exploit these entry points.
  • Install metal mesh or hardware cloth: Cover ventilation openings, gaps around pipes, and other vulnerable areas with metal mesh or hardware cloth. These materials are sturdy enough to prevent rodents from chewing through and gaining access.
  • Keep vegetation trimmed: Trim tree branches and shrubs near your home, ensuring there is enough distance between them and the siding. Overhanging units can serve as a bridge for rodents to reach the siding.
  • Maintain cleanliness: Remove debris, trash, and clutter from around your home, as these can provide hiding places and food sources for rodents. Regularly clean the exterior of your home, including the siding, to remove potential attractants.

Be Proactive Against Pests

It’s super important to stay proactive when it comes to pests and protecting your home and siding. You can totally lower the risk of those pesky critters moving in by being smart about prevention. Keep an eye on things with regular inspections, fix up any moisture problems right away, seal off any openings or cracks, and make sure to keep your surroundings clean and tidy.

Maintaining the integrity of your siding is essential for both functional and aesthetic reasons. If you let pests like termites, carpenter ants, woodpeckers, mold, mildew, or rodents have their way, they can cause some serious damage to your home. So, make sure you stay on top of things and don’t let those critters run wild.

In some cases, professional help is necessary to fight pest infestations and safeguard your siding effectively. Pest control experts know their thing.
