Mice can be, to put it simply, a menace. One tiny mouse can wreak more havoc than you could possibly imagine before you even detect its presence in your home. And seeing as rodents seem to be getting smarter and developing different methods to evade the traps set to kill them or to at least keep them away (they’re actually just afraid of new things), it is no surprise that there have been many methods devised to facilitate their extermination.
One such method is the use of a high concentration of mothballs.
With either paradichlorobenzene or naphthalene as its active ingredient, a mothball is a white ball-shaped pesticide sometimes used to keep pests away.
The purpose of this article is to provide answers to frequently asked questions about the use of mothballs to keep mice away, including do mothballs repel mice in the first place and what mothballs do to mice.
It is important at this point to state that the chemicals that mothballs contain are highly-toxic fumigants that are volatile when exposed to open air. What this means is that mothballs in open spaces react with the air to create fumes that may deter rodents and other pests from that vicinity. However, for mothballs to do more than just cause discomfort to mice and to actually serve as a permanent solution to keep them away, the fumigant concentration must be high.
When applied in a high concentration, the fumigant in mothballs damages the indoor air quality. While this is toxic to mice and rats, it is toxic to humans and pets as well.
Mothballs are a pesticide. Their purpose is to kill moths and their eggs and larvae. As a pesticide, they are regulated by the Environmental Protection Agency (EPA) and any use not specified on the label is illegal. They are only to be used inside airtight containers to get rid of clothes moths. They should not be scattered out in the open where they will release toxic vapors that are dangerous for people and other animals as well as the environment. In addition, mothballs may look like candy to children or treats to a pet. If ingested, the poisons in mothballs can cause vomiting, trouble breathing, seizures, kidney and liver damage, and can even be fatal.
How do mothballs get rid of mice?
Mothballs are not an effective pest repellent. The idea is that when the fumigants in mothballs react with the air, they give off certain fumes that are irritating to mice and rats. As such, rodents are expected to keep away from environments where mothball fumes are present. But, again, the intended use of mothballs is to keep moths and their larvae away from clothing.
The advantages of using mothballs to get rid of mice
- Availability: Mothballs can be easily purchased from online stores or department stores near you. However, beware of illegally-sold mothballs. Their ingredients are not regulated by the EPA and may be more dangerous than legally-sold mothballs.
- Cost: Mothballs are an inexpensive.
- Ease of use: They’re easy to set out. However, they are very dangerous, which outweighs their ease of use.
There are, however, some disadvantages that you should consider.
The disadvantages of using mothballs to get rid of mice
- Toxicity: As stated earlier, mothballs react with the air and release fumes that are toxic to people and could cause illness. In pets and small children, their effects can be fatal. The harm that could come from exposure to a high concentration of the toxic chemicals found in mothballs is one major setback when it comes to using this pesticide. One way to avoid this setback is to leave your house if you set out fresh mothballs in your home.
- Harmful to pets and children: Mothballs are shaped like tiny white balls which is tempting for toddlers who are keen on putting whatever they touch in their mouths. Additionally, your pets could chew on any mothballs they find as well or could be affected negatively by their toxic fumes.
- Ineffective outdoors: Using mothballs outdoors does not work very well as weather conditions such as rainfall can easily dissolve them.
- Potentially ineffective indoors: There is anecdotal evidence that mothballs work and just as much that they don’t. It’s better to keep yourself and your family safe rather than use a dangerous method that may not work at all. Stick to the tried and true methods of sanitation, exclusion, and baiting.
We do not recommend using mothballs to repel mice or any other pest.
