ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to insecticidal bait stations for the control of insects such as cockroaches.
Many devices for holding a poisonous bait to control crawling insects are known, ranging from simple cardboard tubes open at both ends with the bait glued inside, to more elaborate structures that have a centrally enclosed bait accessible by peripheral openings. Some of these insect control devices are configured to hold a solid bait/toxicant preparation. “Solid” in this context means non-pourable and includes pastes, gels, firm solids, and the like. For example, U.S. Pat. No. 4,837,969 shows an insect bait station suitable for holding a solid bait.
Other insect control devices are configured to deliver a liquid bait/toxicant preparation. For example, U.S. Pat. No. 5,033,229 discloses a bait station for passive control of insects, particularly roaches, that provides a source of a liquid bait-toxicant solution, which roaches seek, and U.S. Pat. No. 5,501,033 discloses techniques for the controlled delivery of a liquid insecticidal bait along a vertical axis.
Insect control devices configured to hold both a liquid and a solid bait and/or toxicant preparation are also known. For instance, U.S. Pat. No. 2,167,978 discloses an insect control device having a paralyzing insect powder as well as a liquid aitractant (water) wicked upwardly to a desired position from a reservoir; U.S. Pat. No. 5,339,563 discloses the use of a liquid positioned adjacent an insecticidal material; and U.S. Pat. No. 5,749,168 discloses an insect control device having liquid and solid bait.
In document U.S. Pat. No. 5,749,168 mentioned above and on which the pre-characterized part of claim
1
is based, the liquid is a trapping solution, preferably comprising a mixture of water and household glue.
Insect bait stations that offer a solid poisonous meal and a poisonous drink are quite advantageous, as crawling insects will be able to consume both solid and liquid poisonous materials when looking for water or similar liquids. However, currently available insect control devices that include solid and liquid bait do not provide for a convenient means for sealing the liquid bait during transport and storage and for releasing the liquid bait when the insect bait station is placed into service.
Documents U.S. Pat. Nos. 4,247,042, 4,526,320, 3,727,840 and 5,875,968 disclose vaporizers in which a liquid, for example an insecticide solution or a deodorizing liquid, is contained in a reservoir having a readily breakable closure. The closure is pierced when the device is first activated allowing the volatile liquid to escape.
Despite the existence of this prior art, there is a need for a bait station that provides a convenient means for safely containing the liquid bait during transport and storage, for activating the liquid bait component when the insect bait station is placed into service, and for optionally retaining a solid bait as well.
SUMMARY OF THE INVENTION
The foregoing needs are satisfied by an insect bait station and defined in the appended claims. Such a station has a reservoir for holding a liquid bait, the reservoir having a mouth and a closure for sealing the mouth such that the liquid bait is contained in the reservoir; a piercer for opening the closure of the reservoir such that a liquid wicking device positioned in the mouth of the reservoir may transport the liquid bait from the reservoir and through the mouth of the reservoir; and an activation member for moving the piercer into contact with the closure of the reservoir to open the closure, wherein the station also comprises an insecticide and a solid bait.
