  1. IPM Building Design Frank Meek, BCE Technical Director Paul Hardy Sr. Technical Director

  2. Can You Really Be Pest Proof? • Complete pest proofing may seem impossible • As long as people and products cross the threshold, pest can come in • Idea is to make the building less attractive to pest

  3. What Attracts Pest? • Most pest are drawn to heat, light, smells or combinations • Conducive conditions • Harborage • Food • Water

  4. Odors • Refuse management • Air flow • HVAC • Fans • Doors • Sealing

  5. Light • Type of light • Sodium Vapor vs. Mercury Vapor • Direct vs. Indirect

  6. Heat • The entire building is going to give a different heat signature than the surroundings • No way to avoid

  7. Conducive Conditions • Ground cover • Landscaped • Man made • Condensation drips • Drainage • Food source • Other insects • Refuse

  8. Once They Arrive • Given that heat and light are normally unavoidable, when the pest arrive we must prevent entry

  9. How Do Pest Enter? • Islands • Bridges • Portage • Holes

  10. Bridges • Power lines • Other utilities • Visible • Invisible • Load in / outs

  11. Portage • People carry pest in with them • Employees • Visitors / Guest • Incoming goods

  12. Holes • How much space is really needed for pest entry? • Mice need only ¼ inch to get access • Rats need only about ½ inch • Roaches need as little as 1/64 inch • Termites only 1/32 inch (the thickness of a business card)

  13. New Holes If they can chew it, they can get through it. If a rodent can get its teeth on the surface they can violate it. Not many substrates are immune to the sharp teeth of the rodent.

  14. Surfaces • In order to be somewhat resilient to rodents a surface should be as smooth as possible and kept in good repair. That also means the material chosen for construction is durable and easy to maintain.

  15. Now for Termites

  16. Critical Areas For Termite Intrusion • Outdoor • Sunken window wells • Poorly drained or constantly moist areas in landscape around the structure • Fence post attached to the structure • Tree stumps • Air conditioner evaporation drain lines next to foundation • Exterior planter boxes connected to the structure • Firewood stacked next to the structure and on the ground • Landscape timbers in contact with the structure • Lattice in ground contact around porches and decks

  17. Laundry room water source and pipe entries • Utility room pipe entries • Deck post in ground contact • Deck timber in ground contact or not allowing access for inspection and treatment • Wood steps in ground contact • Support timber in ground contact • Concrete expansion joint material left in place • Sprinkler heads leaking close to structure foundation • Sprinkler spraying toward structure

  18. Sprinkler heads close to structure back spraying on structure • Wood crawl access frame and door in ground contact • Dead tree roots next to structure foundation • Dead plants close to structure • Shrubbery close to the structure, need a minimum 12 inches clearance • Plants growing on structure: ivy, roses, etc. • Ornamentals touching structure foundation , walls or roof

  19. Indoors • Foundation penetrated by utility service: gas, electric, water, drains, etc. • Settlement (shrinkage) cracks • Expansion joints • Plumbing inspection access (bath traps) - install during construction • Interior raised slab expansion joints • Adjoining slabs • Interior drop slabs expansion joints • Addition to main structure foundation walls and expansion joints

  20. Chimney hearth on slab construction generally there is a expansion joint under and behind it • Interior planter boxes • Form boards under suspended porches • Wood support timber in crawl space in or near ground contact • Wood-to-ground contact in crawl space • Form boards in crawl • Cellulose debris on ground in crawl space • Adequate crawl space ventilation or sealed according to building code • Sump pumps not maintained • Dehumidifier not functioning properly

  21. Slabs • Monolithic with post tension support to reduce stress cracks BUT!!!

  22. Grading • Proper grading is to make the structure higher than the surrounding grounds
