Cockroaches dislike the smell of mothballs, making them an effective pest repellent. Mothballs can only keep roaches away for a year or two, as the pests adapt quickly and easily to new environments.
Mothballs – Cockroaches, like moths, dislike the smell of mothballs. A common remedy is to drop a few mothballs behind the stove to keep the bugs from hanging around there. One or two in the cupboard under the sink may also come in handy.
Cockroaches have an incredible sense of smell, which they use to find food. You can take advantage of this fact by using scents they don’t like like thyme, citrus, basil, mint and citronella to drive them out of your home.
Mothballs should not be used near food or food preparation areas. Mothballs should only be used in airtight containers. Gases build up to kill insects that feed on natural fibers. These gases can pose a risk to humans or pets if used improperly.
Mothballs should not be stored in a closet, attic, basement, closet or chest, garment bag, or any other room except in tightly sealed containers as explained above. Gases from the mothballs escape into the air and can cause breathing problems.
Citrus. You may love the smell of fresh citrus, but roaches hate the scent. That means you can use citrus-scented cleaning products in your kitchen and bathroom to drive away any lingering roaches. You can also keep some citrus peels in strategic places around your home.
Did you know that roaches hate the smell of peppermint, lavender, eucalyptus and tea tree oils? This is because it disrupts and masks the scent trails that roaches use to search for their food. Cockroaches die when exposed to higher concentrations of essential oils, especially peppermint oil.
