Apparatus for holding bait including a housing part that can be inserted into a manhole, in particular a sewer manhole or a cable duct manhole, at least one bait platform disposed in the housing part and delimiting at least one passage opening through a rodent can reach a bait disposed on the bait platform and/or a bait held on at least one bait-holding device disposed in the housing part, at least one closing body, which is mounted so that it can be moved relative to the bait platform, wherein the closing body in an open position is moved away from the bait platform, such that the at least one passage opening delimited on the bait-platform side is exposed, and in a closed position is moved toward the bait platform, such that the at least one passage opening delimited on the bait-platform side is closed.

A bait station including a first bait station subassembly and a second bait station subassembly removably-secured to the first bait station subassembly. The first bait station subassembly includes a housing, at least one panel-engaging member and a lid member. The housing has a body defining an axial passage and at least one radial passage in fluid communication with the axial passage. The lid member is hingedly-connected to the housing. The lid member defines a passage. The second bait station subassembly includes a bait spike and a bait spike retainer. The bait spike retainer defines an axial bait spike passage. The bait spike is movably-disposed within the axial bait spike passage of the bait spike retainer and the passage of the lid member. A portion of a bait station is also disclosed. A bait spike assembly is also disclosed. A method is also disclosed.

A bait station for feeding toxic bait to pest animals. The bait station is a generally enclosed structure having one or more open entrances where a pest animal can enter the bait station and feed on toxic bait at a feeding location. Blocking members are disposed in the conduits leading from an entrance to the feeding location. The blocking members prevent the feeding animal from removing bait in stick form from the bait station, and can optionally extend down, outside the bait station, such that the extensions of the blocking members can be used to anchor the bait station to the ground.

Pest control substance delivery systems and methods that optimize substances used to attract and/or poison pests are disclosed. Systems and methods of the present disclosure use information (including input information based on, but not limited to, for example, one or more of the season(s), temperature trend(s) over a period of time(s), length of day(s), change(s) in the length of day(s) over a period of time(s), the deterioration of the potencies of substance(s) based on the exposed shelf-life and/or spoilage of the substance(s), indoor versus outdoor usage, geographical location, species/subspecies, or other input information), to optimize the effectiveness of the delivery of pest control substances over a period of time.

Rat attractant compositions attractive to the rat species Rattus norvegicus are disclosed, which compositions are constituted of compounds found in the headspace volatiles of male urine odor or female urine odor. Said compositions are respectively termed male pheromone blend (MPB) and comprises 2-heptanone, 4-heptanone, 3-ethyl-2-heptanone, 2-octanone, 2-nonanone, and 4-nonanone in a ratio of 10:100:10:1:1:10 respectively, or female pheromone blend (FPB) and comprises 2-methyl-butyric acid, 3-methyl-butyric acid, heptanal, hexanoic acid, 2-phenylacetaldehyde, nonanal, and decanal in a ratio of 20:20:10:30:5:20:10. Devices including the rat attractant compositions, and methods of using said rat attractant compositions, are also disclosed.

Rodent bait station assemblies and methods for assembly and bundling.

A bait station system includes an enclosure formed in part by an upper housing. The bait station system also includes a ramp that forms a bottom wall of the enclosure. The ramp moves from an initial position to an active position in response to a weight that exceeds a target animal weight threshold applied to the ramp. The bait station system also includes a bait hopper that holds bait. The bait station system further includes a bait access chamber that receives the bait from the bait hopper and that is only accessible from within the enclosure while the ramp is in the active position due to the weight applied to the ramp.

An acoustic signal for attracting rats comprising a playback recording or synthetic generation of vocalizations of rats or mice is provided. The vocalizations may be of rat pups, and may be characterized by sonic frequency components in the range of 1.8-7.5 kHz and/or ultrasonic frequency components in the ranges of 21-24 kHz, 40-50 kHz and/or 60-96 kHz. The vocalizations may be of adult male rats, including courting adult male rats, characterized by sonic frequency components in the range of 15-20 kHz and/or ultrasonic frequency components in the range of 20-100 kHz. The vocalizations may be of adult female mice, including nursing adult female mice, characterized by sonic frequency components in the range of 8-12 kHz and/or ultrasonic frequency components in the range of 25-100 kHz.

A bait insert including a tank filled with a liquid bait having a discharge port, a tray top having an engagement port, and a drinking area, wherein the engagement port engages with the discharge port of the tank, and a tray base sealed to the tray top, wherein the tray base includes a plurality of troughs forming an internal flow paths for the liquid bait to flow from the tank to drinking area of the tray top. Further in one embodiment, a bait insert with a spiked tray base having a spike integral to the spiked tray base configured to pierce a foil of a sealed tank is described.

A tamper-proof bait station includes a container having a base and a lid that provides access to an interior that stores a poison bait that is consumed by pests. The base is securable to an external support member that supports the container above a ground surface. The support has an interior that is able to receive a weighted material to restrict movement of the container. A locking cap is provided that locks the lid to the base and is only removably upon applying axial or side pressure to the locking cap.
