This kinda off the wall question. I'm rural and have a septic system. I use liquid safeguard among other types of pest control. Generally, I rinse all containers outside with a hose, however, I need to dose animals? It's raining, cold, and will be for awhile. Will safeguard cause a septic issue. Will it kill beneficial organisms in tank? I know it's a crazy question, but I don't wanna have to pump tank because of not knowing.
