An insect egress device for use with a window or door screen has a portal that is attached to the window screen with a portion of the portal extending through the screen from the inside to the outside. The portal may be provided with various insect attracting features and includes a flange, an extension extending outwardly from the flange surface that terminates at a free end, and an egress passage extending completely through the flange and the extension. The extension has a frusto-pyramidal shaped section and a second extension section that is generally straight and includes the free end. The egress passage has a first sidewall section of a tapering stair-step configuration and a second sidewall section that is not stair-step and is generally straight and terminates at the free end. In aspects, a phosphorescent material is disposed on the first sidewall section and visible through the egress passage from an interior position.

This disclosure relates to an arrangement of equipment with an implement which has a machine tool for a working operation selected from the group comprising maintenance of green areas, mulching, mowing, soil tillage, harvesting coarse fodder, harvesting cereal crops and spraying, and which has an active portion which can be moved in a working direction through a working region. The arrangement of equipment includes a blower for blowing small creatures out of a portion of the working region preceding the active portion of the machine tool in the working direction.

A mosquito control net includes an occupant chamber and a trap chamber disposed over the occupant chamber. The trap chamber has one or more openings disposed on an outer surface thereof, through which mosquitos enter the trap chamber, the openings having receptacles attached therein and extending within the trap chamber to inhibit egression of mosquitos from the trap chamber after entry. A method for preventing mosquito bites for a subject can include providing such a mosquito control net and having the subject occupy it. A kit of parts for converting a conventional mosquito control net into a trapping mosquito control net can comprise a funnel-shaped receptacle surrounded by a bag, the bag being substantially impermeable to mosquitos and the receptacle and/or the bag being attachable to a top surface of the conventional mosquito control net to form a trap compartment.

A detection chamber assembly of a smoke detector is provided. The detection chamber assembly includes upper and lower covers, louvers and a corrugated bug screen. The louvers are arranged with the upper and lower covers to define a chamber bound between the upper and lower covers and the louvers. The louvers include a first pair of louvers defining a first space therebetween to permit fluidic ingress to the chamber and a second pair of louvers defining a second space therebetween to permit fluidic ingress to the chamber. The second space is wider than the first space. The corrugated bug screen includes a body disposed about the louvers and a mesh corrugation feature coupled to the body at the second space to permit fluidic ingress to the chamber at the second space and to inhibit bug ingress to the chamber at the second space.

A pest control assembly is configured to prevent pests from entering a structure. The pest control assembly has a plumbing system, with a drain line joined to a first cleanout. A ledge is arranged on the first cleanout. A pest control insert placed upon the ledge and further comprising a cylindrical body further having a plurality of openings are arranged upon an upper half of the cylindrical body. A chlorine gas emitted from the cylindrical body through the plurality of openings prevents pests from entering the structure.

An active barrier to termites and other insects includes a polymeric or paper substrate; and a copper-carbon matrix, wherein the copper-carbon matrix is incorporated into or is coated onto the polymeric or paper substrate. The resulting combination of the substrate and copper-carbon matrix allows for the creation of films, tapes, coated paper and fabric, or molded or formed parts that interfere with and block the passage or entry beyond the barrier of termites or other insects. Uses may be as diverse as but not limited to underlayment(s) for temporary, semi-permanent or permanent structures as well as films and barriers for walls, roofs of permanent, semi-permanent or temporary structures, or interior spaces, cabinets, or vehicles or protecting equipment, telecommunication gear, electronics or other assets that may be impacted, damaged or degraded by termite or other such insect infestation.
