Special Requirements 2

Pest Control Design Criteria

1.	Exterior Light Fixtures: Exterior light fixtures shall be designed so that birds cannot roost or nest on or in them.
2.	Exteriors Doors: Gaps at exterior doors shall not exceed 3/16" for non-collection facilities. There shall be NO gap in exterior doors for collection facilities.
3.	Ventilation: Use reinforced fiber filters over greenhouse cooling pads, vents, and shutters to screen out plant pests and to screen in biological controls. See Attachments A and B.
4.	Pipe Insulation or Furniture in Laboratories, Kitchens, and Animal Rooms: All pipe insulation must have smooth surfaces with no gaps. Do not install pegboard in kitchens, animal rooms or laboratories. All permanently installed furniture in kitchens, animal rooms and laboratories must be sealed at points of attachment, under counter tops, and inside to prevent pests from harboring in the gaps. All built-in cabinets, closets and similar casement/millwork must be sealed leaving no gaps for pests to hide in.
5.	Landscaping: Decorative lattices (bird roosts) shall not be placed over entrances to food services facilities. Maintain proper earth to wood clearance and proper drainage away from structures. During landscape renovation, do not raise the soil level against the building. Do not plant Monterey and Bishop pines near pedestrian areas (blackbird nesting).
6.	Windows and Doors in Museum and Collection Storage: Windows opening to museums and collection storage areas must be screened to exclude museum pests (beetles and moths). Interior doors in museums and collection storage areas must be tight-fitting, including sweeps, to prevent pests (beetles, mice and moths) from passing through.
7.	Windows and Doors in Museum and Collection Storage Windows opening to museums and collection storage areas must be screened to exclude museum pests (beetles and moths). Interior doors in museums and collection storage areas must be tight-fitting, including sweeps, to prevent pests (beetles, mice and moths) from passing through.
8.	Exterior Pest Barriers and Seals: Seal all construction from foundation to roof to prevent access by pests such as bats, birds and rats. Porches and ramps shall be sealed to the foundation, or 1/4" galvanized mesh shall be used to form a barrier to digging pests (rats and skunks). This screen must extend 12" into the ground and must have a right-angled, 6" wide, outward extending shelf to prevent burrowing under the screen.
9.	Roof Tiles: Eave roof tiles shall have bird stops to exclude bats, bees and umbrella wasps.
10.	Ventilation: Ventilation louvers shall be screened with wire mesh to exclude birds, rodents, cats, etc., (coordinate with mechanical requirements).
11.	Windows - Frame Design: Weepholes in window frames shall be designed to prevent access by paperwasps. Windows shall be designed to prevent harborage and access for pests with no clear passageways to inside.
12.	Slab Construction: Use a 3" layer of sand (#3 Lapis available from RMC Lonestar) for the sand barrier underneath slab construction. Use #3 Lapis in place of unsifted sand to provide a permanent sand barrier to termites (both western subterranean and Formosan termites). This will prevent termites from penetrating cracks in slab construction.

Advantages are:

a.	Commercially available (from RMC Lonestar near Monterey, order ahead to make sure an adequate supply is available).
b.	The use of a sand barrier is a practical proven method and is required by building codes in Hawaii and Sydney, Australia.
c.	The barrier is permanent (current termiticide chemicals are only effective for about ten years).
d.	No hazardous chemicals are involved. Termiticides in soil make the soil a hazardous waste.

Disadvantage is:

a.	The cost of #3 Lapis sand is approximately twice that of unsifted sand. This differential is reduced by the cost of termiticide applications that are no longer needed.
