A pest barrier (10, 10′, 10″, 10′″, 10″″), comprising a body (12, 112) for installation in or over an opening in a building to inhibit passage of pests through the building opening (200, 302). Body (12, 112) is formed from one or more components and comprises one or more first opening (18, 28, 29, 116) extending therethrough to facilitate ventilation through the building opening when the body is installed therein or thereover. A pest repellent is carried by at least part of body (12, 112) and has efficacy within a first zone extending a predetermined first distance inwardly from a perimeter of the one or more first opening (18, 28, 29, 116) to deter one or more target pest species from passing through the one or more first opening and/or within a second zone extending a predetermined second distance outwardly from the body (12, 112) toward the periphery of the building opening (200, 302) to deter said one or more target pest species from passing through each of one or more second opening in the second zone.

A barrier system includes a substantially vertical structure with a coating layer disposed on and circumscribing a majority of the substantially vertical structure. The coating layer has a height of at least 0.25 inches, has gouge and scratch hardness of at least 2H, and has an average surface roughness (R.sub.a) of less than 10 microns.

A barricade used to obstruct the gap between a garage door, weather stripping, a threshold surface and a door frame. The barricade successfully prevents pests from breaching the barricade. The barricade uses a spring assist with low displacement force in order to conform to the changing downward or upward angle when a garage door is being operated. It also includes smooth ceramic or rubber that is magnetized to prevent chaffing to the garage door surface. This barrier stays in-place or rotates relative to the garage door face when encountering foreign objects in the path of the moving garage door. Alternatively, the barriers may be constructed of overlapping and/or abutting material configured to obstruct gaps at door frames and/or at threshold surfaces where a weather stripping and/or weather-stripping bulb provide inadequate obstruction.

The invention provides an invertebrate pest detention profile for an extruded channel of rigid or flexible material which may be deployed as a partial or open contour, or a closed contour to establish a defensive line or perimeter to prevent crawling pests or invertebrates such as slugs from traversing the line or boundary. The profile provides a moat for offering a liquid or viscous attractant which retains pests by intoxication, or simply provides a shape too complex for them to overcome. The detention profile disclosed herein may be a component fitted to or incorporated within a garden pot, or built up from components of a pot for a garden plant to deny invertebrates or crawling pests access to a plant in the pot. The detention profile also hides the pests from immediate view and hinders access to them by pets or children.

An anti-rat flap member for sewer/draining pipe check is removably attached to the valve body. The valve body defines an interior volume therein which is preferably substantially open and unobstructed (except for the flap member). The flap member acts both as a seal to prevent the back-flow of sewage/drainage water and is normally in a closed position to prevent the passage of rats. The flap member comprises a row of sharp projections attached by known means (such as integrally molded, glued, rivetted or screwed) to the outermost side of the flap member facing the downstream section of the valve. The projections must be at an angle to the surface of the sheet, preferably at an angle which will prevent the rodent from gnawing and biting or even lifting the flap member with their mouth.
