How to Use Mothballs As a Lizard Repellent

Updated April 17, 2017

The effectiveness of mothballs as a lizard repellent is not verified. Many people are convinced mothballs are effective for repelling lizards and snakes; other people are concerned that other birds or wildlife can be harmed by them. Mothballs can be toxic, so it is best to use them where they will not be found by small children, pets or other animals. In addition to repellents, there are other steps you can take to deter lizards and other pests from entering your home or garden.

Place mothballs on window sills to deter lizards from coming inside. Seal cracks with caulk, if there are gaps in the seal of the window.

Scatter a few mothballs near entrances and doors to deter lizards and other pests from entering the home. The smell of the mothballs repels lizards and snakes. Put the mothballs in an open container, if you do not want to scatter them on the ground.

Put one to three mothballs in potted plants to repel lizards and other pests. Replenish the mothballs when the rain washes them away.

Place mothballs about one foot apart in garden areas or other perimeters. Place mothballs around the edges of the garden, or up and down the rows.


Mothballs are toxic to humans and animals. Keep mothballs well-sealed and out of reach, when not in use.
