Provided is a pest control device with which it is possible to reliably exterminate pests in a cultivation room. This invention is provided with a spraying means equipped with nozzles for spraying a chemical solution containing a pest control agent into a plant cultivation room. Liquid droplets being sprayed from the nozzles measure 100 m or smaller, and have an average particle diameter of 10-30 m. The nozzles are disposed so that the spray from the nozzles fills the entirety of the plant cultivation room interior in a uniform manner. The invention is provided with a control device for causing the nozzles to spray so that the humidity in the plant cultivation room is 90-100%.

In a system (10) for managing a soil treatment business, an injection apparatus (12) is operable to inject soil treatment under high pressure down into soil. A control system (92) is associated with the injection apparatus (12) and is configured to collect data during operation of the injection apparatus (12). A data management system (801) is configured to receive the data collected by the injection apparatus (12) control system (92). The data management system (801) generally comprises a database for storing the collected data, with the data management system being accessible by the business for reviewing the collected data.

A system and method of monitoring and controlling cellulose-consuming pests in a predetermined location with existing wells formed in the ground, provides for the use of an assembly that has a main body with a transverse upper lip, a flexible resilient sealing member fitted underside the lip in a surrounding relationship to the main body, and tightening bolts extending through the lip and the sealing member. When torque is applied to the tightening bolts, the sealing member is then compressed, causing it to expand horizontally and engage the interior walls of the existing well by sealing same. The main body is configured to removably receive one or more bait unit therein. A cap covering an open top of the main body covers the bait units when the system is positioned in the well.

In a method for treating soil at a work site, a first pressure application tool is connected to a base unit and moved relative thereto along a first area of the work site adjacent a structure and operated to inject soil treatment down into the soil along the first area of the work site. A second pressure application tool is interchanged with the first pressure application tool and moved relative to the base unit along a second area of the work site adjacent the structure and different from the first area of the work site. The second pressure application tool is operated to apply soil treatment to the soil along the second area of the work site.

A termite barrier seal including a hollow seal body having a wall surrounding an axial bore extending from an insertion end to a surface end. A closure formation is located about the surface end for engagement with a closure for the orifice of the bore at the surface end of the seal body. A one-way valve at or intermediate the insertion end and the surface end of the seal body, the one-way valve arranged to permit liquid flow through the axial bore, but to prevent liquid flow to the surface end. An external seal about the seal body for sealing the wall of the seal body against the internal surface of a hole drilled through a concrete slab. An internal seal engages the seal body for sealing the wall against an external face of an injector when inserted into the bore of the seal body.

A light assembly (10) for installation in a greenhouse comprises a light unit (30) and at least one light fixture (20) mounted thereto. The light unit (30) comprises a light unit body comprising a light mounting structure (200), and a plurality of light sources mounted to the light unit body along a row. The light fixture (20) comprises a light fixture body comprising a light mounting structure (100) for mounting a light unit (30) thereto with thermal connection therebetween, a first passage (140) comprising an entry port (142) and an exit port (144) for a cooling fluid to circulate to dissipate heat conducted from the light unit (30) into the light fixture (20), a second passage (150) comprising an entry port (152) for receiving vaporizable compounds, and vaporization ports (160) fluidly connected to the second passage (150).

There is provided a method for the removal and control of arthropod infestation comprising the cleaning of surfaces and objects within an interior dwelling space using a high efficiency water extraction device, utilizing water that is heated to a temperature sufficient to kill the pest, and to which is added a cleaning agent comprising a surfactant that imparts a surface tension of between about 15 and about 30 dynes/cm, (a super wetting agent); in combination with application of an effective arthropod control composition to surfaces and objects within the interior dwelling spaces, the arthropod control composition comprising an arthropod control agent and a surfactant that imparts a surface tension of below about 30 dynes/cm.

In a method and apparatus (710) for treating soil at a work site, a high pressure application tool (712) is connected to a base unit (714) and moved relative thereto along a first area of the work site adjacent a structure (94) and operated to inject soil treatment down into the soil along the first area of the work site. A low pressure application tool (711) is interchanged with the high pressure application tool (712) and moved relative to the base unit along a second area of the work site adjacent the structure (94) and different from the first area of the work site. The low pressure application tool (711) is operated to apply soil treatment to the soil along the second area of the work site.

An improved system, apparatus, and method for use in controlling subterranean termite populations are described. It is determined whether one or more of the sensor characteristics in one or more of the underground soil regions are indicative of a subterranean termite population exceeding a threshold. Based on the determining, a treatment need is identified for the one or more underground soil regions. The treatment need is executed at regions corresponding to the one or more underground soil regions.

The present invention resides in a collar assembly to impede ingress of insects through a concrete slab, the collar assembly comprising two or more base members; and at least one flange member slideably engageable with the two or more base members. The present invention alleviates the problems associated with ingress of insects through a space between pipes and a concrete slab.
