Abstract: Gasket devices having a crawling arthropod deterring substance for fitting adjacent to connection points to permanent fixture objects on walls, ceilings and floors to interior spaces. The novel gasket devices can be used for protecting gaps and spaces between permanent fixtures such as shower heads, faucets, drainpipes, incoming waterlines into various rooms such as but not limited to bathrooms and/or kitchens, and anywhere these fixtures exist. Additionally, the gasket devices can be used for protecting gaps and spaces between other permanent fixtures such behind plates such as but not limited to electrical sockets, switches, cables, telephone jacks thermostats, and the like. Additionally, the gasket devices can be used behind ventilation vent covers, and the like. Finally, the gasket covers can be used about wall mounted stems of on hanging fixtures such as lights, chandeliers, and ceiling fans, and the like.

Abstract: A barrier implement intended for obstructing a route of travel of crawling arthropods along a passageway comprises a sheet configured to circumscribe a passageway along which arthropods crawl. A dimension of the sheet is sized or molded relative to said passageway. An arthropod deterring component associated with said sheet for deterring said crawling arthropods and impeding their route of travel along said passageway.

Abstract: An air supply system having a multi-cylinder, two-stage air compressor including a pair of low pressure cylinders and a high pressure cylinder. A first intercooler interconnected between the outlet of one of the pair of low pressure cylinders and the inlet of the high pressure cylinder and a second intercooler interconnected between the outlet of the other of the pair of low pressure cylinders. An aftercooler connected to the outlet of the high pressure cylinder for effectively reducing the temperature of the compressed air supplied to a storage reservoir to near or at ambient temperature. A protective housing including a frontal screened opening for permitting a rotary fan to draw cooling air into the housing and including an internal shroud for directing the cooling air over the intercoolers and aftercooler.

Abstract: A packaged bait system for the control of insects, especially cockroaches and other orthopterous insects, comprising an insecticidal food bait composition housed in a bait block holder that allows for easy placement in locations where the probability of encounter by the target insect is high and that makes the bait readily accessible to the target insect. The toxic bait comprises corn distiller's grain, a humectant, an insecticide and a gel former to yield a deformable hydrophilic gel matrix subsequent to hydration.

Abstract: A composition and method for the regulation of the growth and mortality of cockroaches based on the administration thereto of allopurinol.
