what are naphthalene balls - #24135

Naphthalene balls, sometimes called mothballs, are made from naphthalene, a type of hydrocarbon that is effective in repelling pests, especially moths. They release a strong odor due to sublimation, where the solid changes directly into a gas. This odor is effective for pest control, but yes, it can be a concern. They are considered toxic—both to humans and animals—primarily due to the inhalation of their vapors over prolonged periods. Symptoms of exposure may include headaches, dizziness, and nausea for humans, and yes, it can lead to lethargy or more severe symptoms in pets like dogs.

Your concern over their strong smell is quite valid. If your dog has started showing signs of lethargy, it could be a reaction to these chemicals. It’s always a good idea to limit your exposure to such substances, especially in a home environment where you and your pets spend a lot of time.

As far as natural alternatives go, you have several options. One common method uses essential oils, such as peppermint and lavender, which have natural pest-repelling properties. You can create a spray by diluting these oils in water and apply it in a similar fashion around areas prone to pests. Keeping your home clean and free from excess moisture can also help prevent pest infestations.

Consider using cedarwood, an old-time remedy, which is generally safe for pets and humans, and it naturally deters moths and other insects without releasing harmful chemicals into the air. You can place cedar blocks or chips in your cupboards or wardrobe where moths are likely to be.

If symptoms persist with your dog, I would recommend consulting a vet, as their advice would be more specific to the situation. And assessing the ventilation in your grandma’s home, opening windows to allow the air to circulate could also minimize exposure. Always ensure that pest control measures are safe for everyone’s health in the household.
