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

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

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

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

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

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

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

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

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

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

12. Holes How much space is really needed for pest entry? How much space is really needed for pest entry? Mice need only ¼ inch to get access Mice need only ¼ inch to get access Rats need only about ½ inch Rats need only about ½ inch Roaches need as little as 1/64 inch Roaches need as little as 1/64 inch Termites only 1/32 inch (the thickness of a business card) 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. In order to be somewhat resilient to rodents a surface should be as smooth as possible and kept in good repair.
