Said porous cellulose acetate may be one which is surface-saponified. Examples of the odoriferous substances include volatile substances such as insect repellents, antibacterials and mold inhibitors. Said porous cellulose acetate molding can adsorb the odoriferous substances fully without substantially changing its shape and persistently volatilize the substance for a long time.

Abstract: A molded non-layered unitary article (serving as a larvicide carrier) is formed solely from a substantially homogeneous mixture consisting of cork particles and a molding- type of plaster into which a larvicidal micro-organism, such as B.t.i., has been added. The article may be dispensed conveniently, on to either small or large bodies of water, without regard for its orientation relative to the body of water. The article has a specific gravity of less than 1.0 and floats freely on the surface of the water, but if desired, may have a restrained-floating application. A sustained release of the larvicidal micro-organism is assured for effective mosquito control. All of the ingredients are found in nature, are bio-degradable, and are non-toxic to non-target organisms; hence will not adversely affect the environment. In a preferred embodiment, the article is substantially-toroidal and slightly-tapered and is provided with a central opening therein.

Abstract: A bait station for rodents, an elongate, hollow tubular structure having a single opening to and from its interior. This station is formed of tubing fabricated, preferably, of tough, corrosion, weather and distortion resistant plastic such as a polyvinylchloride. Its preferred configuration provides that one end portion of its tubular structure is enlarged as to its cross sectional area to define a bait chamber the entrance to and exit from which is limited to a single passage, defined by its remaining length the remote end of which provides the single opening to and exit from the passage. The cross sectional area of said passage is made substantially less than that of said chamber. This precludes entrance by animals larger than that of the target rodents. Preferred bait embodies a non-poisonous anti-coagulant, ingestion of which produces a breakdown of the rodent's life support system and its expiration, but not until some time after the rodent leaves the vicinity of the bait station.

Abstract: A tamper resistant bait station for holding a supply of rodent or other pest bait is disclosed having an outer housing and a tray slidably received within the housing, and is secured in its received position by a tamper-resistant closure. The floor of the housing and the floor of the tray are elevated above the ground and have entrance openings therein in register with one another when the tray is inserted in the housing so that a pest, such as a mouse or rat, may enter the housing and the tray from below via the entrance openings. Partitions within the tray define the various passages and compartments within the tray, these partitions having notches or other openings therethrough to permit the pest to travel from the entrance openings to the bait compartment and to exit the bait station, but yet preventing tampering with the rodent bait and preventing protected wildlife from entering the bait station. The station may be secured to a wall or the like.

Abstract: A telescoping container comprising a bottom section having a bottom wall and a plurality of side walls normal to the bottom wall and a cover section having a top wall and a plurality of side walls normal to the top wall; the side walls of the cover section extending on the outside of the corresponding side walls of the bottom section. A flap is externally secured to each of a pair of outer walls of the bottom section and a corresponding flap on corresponding walls extends inwardly of the cover section; this pair of flaps on the inner walls of the cover section passes the corresponding flaps on the outer walls of the base member when the cover section is placed on the bottom section and interlocks when the cover section is withdrawn. The top and bottom walls are caused to be bowed concavely. The bowing of these walls exerts outward forces on the interlocking flaps which, in turn, improves the locking action of the flaps when the cover section is fully extended from the bottom section.

The housing has a cover which provides an overhang over the doorways so as to prevent water entry from sprinklers or rain as well as to provide an inviting hiding place for snails and slugs. A pesticide is disposed in the housing as well as a dry bait attractant, the latter of which is activated by water from a water reservoir provided in the cover.

Abstract: A method and composition for dispensing through a slow release floating polymer a pesticide for destroying aqueous pests, especially mosquito larva. The polymer matrix which has a specific gravity of less than 1.0 so that it floats, may be shaped into any geometric design such as a thin strip or tape and is anchored by an attached weight having a specific gravity greater than 1.0. The floating polymer assures slow release of the insecticide in that it is not covered by debris or silt as would occur with a sinking polymer matrix. The floating matrix can be utilized wherever desirable in slow turnover or stagnant waters, such as in lakes, ponds, swamps, storm sewer catch basins and portable water containers such as rain barrels, and the like. The floating member generally can contain any pesticide for the elimination of any specific pests or insects. The polymer of the matrix is a copolymer of ethylene-vinyl acetate and/or an ethylene-propylene copolymer.
