Pests enter through sliding doors because of gaps in weatherstripping, damaged seals, dirty tracks that provide food sources, and lubricants that actually attract insects. In Hampton Roads, where warm weather and high humidity create an active pest environment for most of the year, your sliding door is one of the most vulnerable entry points in your home. Sliding doors have more potential gaps than a standard door or window. The track channel along the bottom, the weatherstripping along the edges, the junction between the sliding panel and the fixed panel, and the threshold seal all create opportunities for insects and small pests to find their way inside.
