Chipmunks rule the land. The cute little critters dig holes all around my house.
My sister suggested placing mothballs—those old-fashioned white, pungent balls grandmas used decades ago—along the perimeter of the house to ward them off. I don’t know how many chipmunks they kept away, but I couldn’t stand the smell and found that I was avoiding everywhere that the mothballs were. I retrieved and tossed them all. Surprisingly, the trash can smelled from them for weeks afterwards.
Mothballs are small balls of chemical pesticide and deodorant used to protect clothes from mold, moth larva, and silverfish. It also may repel snakes, mice, and other small pests. Not only is their smell offensive and overpowering, mothballs pose some serious health hazards. They must be used with great caution around family pets and children.
The ingredients have changed over the years but they continue to be somewhat flammable. They contain a chemical called 1,4-dichlorobenzene. Sometimes packaging lists it as para-dichlorobenzene, p-dichlorobenzene, pDCB, or PDB.
Mothballs are highly toxic when ingested. The US Department of Health and Human Services has determined this ingredient to be a carcinogen. It is a neurotoxin and may cause series illness or death. Large quantities in a basement or living space may also cause respiratory problems.
A better alternative to mothballs may be to spread blood meal or pieces of unchewed sticks of fragrant gum near chipmunk holes.
