The Myth of Bleach as a Mole Repellent

Will bleach kill moles? Many people often ask this question. Bleach is not so effective in killing moles but in killing other pests. Moles are rarely exposed to bleach as they live underground. If by any chance they come into contact with bleach, the chances of them dying are very low.

Using bleach as a repellent can be harmful. Bleach is venomously dangerous and toxic for humans and other living beings. It can cause breathing problems in humans and may even cause death if inhaled in large quantities and left untreated. To kill the moles, you will have to spread them everywhere, which might destroy the soil, causing the death of many plants.
