A method of treating drain systems containing organic matter and providing a pesticide for killing insects is provided. Introducing a bacterial culture into a drain system that is operable to metabolize organic matter will reduce the quantity of the organic matter in the drain system. Introducing a biocidal amount of fungus culture such as, Metarhizium, into the drain system allows for exposure of the fungus to insects which feed on the organic matter in the drain system. The insects, once infected, will spread the fungus to other insects. The fungus, provided in suitable quantities, will kill the insects. The insect is infected through contact or ingestion. The drain system can be a residential or commercial drain system. The fungus can be intended to kill insects that are cockroaches or other soft-bodied insects. The bacterial cultures can be separately sprayed into the drain or dispersed together into the drain with the fungus. The bacterial cultures and the fungi are maintained separately and then mixed for the treating of the drain. The cultures are maintained together prior to introducing them into the drain. The cultures can be dispersed as a spray, a powder, a liquid, or a foam.
