A pest control dispersal spray system for a building preferably includes a reservoir having a cavity housing a pest control agent. The reservoir has a discharge mechanism selectively expelling the existing pest control agent outwardly and away from the reservoir while the reservoir remains at a stationary position. A discharge nozzle may be attached to the reservoir and may be in fluid communication with the cavity. A plurality of interconnected tubes may be located exterior of the reservoir and may be in fluid communication with the discharge nozzle. In this manner, activation of the discharge mechanism causes the existing pest control agent to flow through the cavity, egress the reservoir via the discharge nozzle, and thereafter travel along the interconnected tubes such that the existing pest control agent is dispersed outwardly from the interconnected tubes while the reservoir remains stationary.
