Are Mothballs an Effective Rodent Repellent?

Dealing with rodent infestations is an age-old problem with a seemingly mothballsendless number of different “solutions.” Some of which include poisons, glue traps, and traditional snap-traps. Perhaps the most popular DIY method for rodent and reptile repellent however is the use of good old fashioned mothballs. But, is this actually an effective solution?

Mothballs are both cheap and readily available, which helps make them a popular choice – you can even buy them at most department stores. Then you simply spread them around the infested area, adding more as needed. Seems perfect right? Well, there are a few problems.

  • They can pose a danger to small children or pets, as they are curious. Mothballs are small, white items that can attract attention – often resulting in them ingesting the ball, which can lead to serious health issues.
  • If your rodent problem is outside, mothballs will dissolve in the rain or can be blown away by gusty winds.
  • Mothballs are not a proven way to get rid of rodents. They find the smell of mothballs to be off-putting, but they will often just avoid the affected area but not leave your property.

The repelling ingredient in mothballs is a chemical called naphthalene, which is a strong smelling, white substance. When ingested it can prevent blood cells from carrying oxygen, which should theoretically make it an effective repellent. The problem, is that mothballs contain very little of the chemical, and as a result, some rodents have been documented ignoring mothballs all together.

Even if the rodents are put off by the mothballs, they are cunning creatures and will find another way to access their nest, or will build a new nest all together.
