- Blocking entry points: One of the main ways pests enter a home is through small gaps and cracks around doors and windows. A properly installed door threshold can help seal these openings, making it more difficult for pests to infiltrate the interior of the house.
- Preventing air currents: Aside from keeping pests out, door thresholds also play a role in minimizing the circulation of air currents. This is especially important for flying insects like mosquitoes and flies which rely on air currents to navigate. By reducing the airflow through the gap beneath the door, thresholds can impede the entry and movement of these pests.
- Acting as a physical deterrent: Some pests, such as mice and rats, can be discouraged from entering a property if they encounter physical barriers. Door thresholds, especially those made of sturdy materials like metal or hard plastic, can act as an obstacle that pests are unlikely to be able to pass through.
Types of door thresholds:
- Weatherstripping thresholds: These thresholds typically consist of a strip of flexible material, such as rubber or silicone, attached to a metal or plastic base. Weatherstripping thresholds are designed to create a tight seal against drafts, noise, and moisture, but they can also help limit pest access if properly installed.
- Raised or barrier thresholds: Raised thresholds are generally taller than weatherstripping thresholds and are designed to physically block pests from entering the home. These thresholds may have a beveled edge to prevent tripping, but they still create a more significant barrier compared to other types.
- Pest control thresholds: Some manufacturers now offer door thresholds specifically designed to combat pests. These thresholds incorporate additional features, such as insect screens or repellent coatings, to further enhance their ability to limit pests.
Installation and maintenance tips:
- Ensure the door threshold you choose is compatible with your door type and size.
- Measure the gap between the door and the floor accurately to guarantee a proper fit.
- Clean the threshold regularly to prevent debris buildup, which may create gaps or attract pests.
- Inspect the threshold periodically for damage and replace it if necessary to maintain its effectiveness.
While door thresholds primarily serve as a barrier against drafts and noise, they can also play a significant role in limiting pests’ access to your home. By correctly installing and maintaining a door threshold, homeowners can reduce the likelihood of unwelcome critters invading their living spaces. Whether opting for weatherstripping, raised, or pest control thresholds, the benefits of these devices make them a valuable addition to any pest control strategy.
