Mothballs are made of naphthalene, which is a chemical that kills insects and may repel animals. However, the vapors of these products can be dangerous to your health, and they should only be used in an airtight space. They should never be placed in a closet or plastic garbage bag because the vapors will persist in the air for a long time.
Another natural way to keep bed bugs away is to spray tea tree oil on the bed. This oil is a natural insect repellent that will kill bed bugs as well as their eggs. Another effective natural remedy for bedbugs is lavender oil, which is pleasant to the human senses and can repel bed bugs.
Despite the effectiveness of mothballs, many people still have reservations about their safety. There are a number of known toxins in mothballs, including PDCB and naphthalene. Some of these chemicals are carcinogenic, according to the US Department of Health and Human Services. They can also be choking hazards, especially for small children. For these reasons, it is best to consult a pest professional before using mothballs in your home.
One of the major problems with mothballs is the smell. The odor is so bad that it can be toxic for children. Also, mothballs can only protect a small area, and the noxious gas they emit can disperse bedbugs into new areas.
