ABSTRACT:
In order to achieve effective control of pests (such as insects and rodents) in residential and commercial buildings, a permanently installed pest control system is disclosed which is particularly adapted for incorporation into existing structures without substantial modification. The system includes an exterminating liquid supply subsystem and an exterminating liquid distribution subsystem. The supply subsystem includes a replaceable exterminating liquid reservoir, an electrically driven pump and switch means (which may include a time clock and a short term timer) coupled to a source of electrical energy to selectively energize the pump. The distribution subsystem includes a trunk tube connected to the pump to receive pressurized exterminating liquid drawn from the reservoir and one or more branch tubes extending throughout the building at a position near the floor, each branch tube having a plurality of outwardly directed small apertures piercing its wall at intervals along its length to effect nozzles through which pressurized exterminating liquid is dispensed into the inter-wall space and/or onto the area at which the wall and floor meet. Optionally, a pressure sensor may be placed on the output side of the pump to provide an indication of an empty reservoir (pressure drops below normal) or a substantial blockage in the distribution system (pressure rises above normal).
