Proactive Pest Management | Man Made Harborages
Man-made harborages include, for example, the areas underneath boards,patio stones, potted plants, garden statues, decorative rock piles, garden barriers, and other flat items lying on the ground. Keeping such garden decorations away from the foundation and exterior doors will reduce the potential for pests to harbor near the home and thus their chance of entering. Man-made harborages also include trash and garbage piles, firewood, the interior of hollow retaining walls, and the areas in and between crosstie or landscape timbers used around flower beds (Figure 4).
The structure itself can be viewed as a nearly endless series of man-made voids, behind cracks and crevices, that can serve as harborage for pests. Any crack or crevice in a structure that leads to a void will invite certain insect pests to harbor in that space, especially if food and water are available or the space enhances survival and growth. Common harborage sites within a structure include large areas such as crawlspaces (especially those without a vapor barrier and/or proper ventilation), attics (especially those with leakyroofs), and a wide variety of wall voids (the space defined by the interior and exterior siding on wall studs) (Figure 5).
There also are numerous small voids, such as the space between the dishwasher and kitchen cabinets,the space behind baseboards, the area between built-in cabinets and the wall, inside appliances and furniture, or gaps on the exterior cladding (boards, siding, brick veneer weep holes). Structural harborages can be made unusable by sealing cracks, crevices and other entryways. Inside homes clutter also provides harborage, and sometimes food, for pests. Clutter can be defined as persistent piles of clothing, books, paper bags, boxes, papers and newspapers, recyclables, etc. (Figure 6).
