When you get enough drowned roaches in a jar, remove the cup of coffee grinds and dump the water with dead roaches into the toilet. Refill the jars with water and coffee grinds and place them back against the walls and baseboards. Repeat this process daily until the roaches are completely gone.
For kitchen deterrents, cockroaches dislike the smell of cinnamon, bay leaves, garlic, peppermint, and coffee grounds. If you want a strong-smelling disinfectant, choose vinegar or bleach. The best scent-based deterrents are essential oils, such as eucalyptus or tea tree oil.
Cockroaches are attracted to coffee makers because they're a source of: Warmth. Moisture. Food.
This simple home remedy for infestations involves putting dryer sheets into the favorite hiding places of cockroaches. Dryer sheets contain linalool, a naturally occurring substance found in certain plants. While dryer sheets won't kill cockroaches, linalool can be a roach repellent.
White vinegar is often recommended as a natural way to get rid of roaches. Unfortunately, it doesn't actually kill these problem insects. It's more of a cleaning tool than anything else, and it won't actually help eliminate your roach problem.
Roaches are repelled by ground coffee. In fact, putting some ground coffee down in the corners or windowsills of your kitchen can actually help keep them insects away.
Pine-Sol and Fabuloso are strong, all-purpose household cleaners. Similar to bleach, these products kill roaches on contact. Some homeowners suggest spraying Pine-Sol around the outside of your house to keep cockroaches away.
While many insects are repelled by the smell of coffee, roaches are attracted to it. You can make your own roach trap by putting damp coffee grounds in a jar and lining it with double-sided tape.
As it turns out, roaches actually like living in coffee machines. I read up on this and, sadly, it's pretty common to find roaches in coffee makers — because there are so many warm, moist, dark spots inside for them to hide out.
Sugars. Cockroaches are primarily attracted to sugar. Sugar used for tea or baking should be sealed tightly, or cockroaches may get into the package. Soda and juice attract cockroaches, because of the high concentration of sugar in them; even a spilled sugary drink that has dried can be smelled.
Cockroaches have an incredible sense of smell that they use to find food. You can take advantage of this fact by using scents they dislike such as thyme, citrus, basil, mint, and citronella to repel them from your home.
Add some food like a small piece of meat or some sweet stuff like chocolate on the roach bait in the bowl. Keep the bowl near one of the hiding places of roaches. To cover all the hiding places, you'll need multiple bowls with sticky roach trap and food. The smell of the food will draw the roaches out.
Does Cinnamon repel cockroaches? No, cinnamon doesn't repel cockroaches. But there're are other essential oils or spices that can work against cockroaches. You can use bay leaves, garlic, and catnip to reduce some amount of cockroach activity in your home.
Lavender. Cockroaches hate the smell of lavender, and that is good news for you. If you love to grow lavender in your yard and garden, you are more than halfway to a roach-free home.
Another popular home remedy for cockroaches is cleaning your house with lemon juice and water. We agree that this is a good idea, but because of the cleaning part (see below), not because of the lemon. Lemon contains limonene, which does in fact repel cockroaches.
Boric acid is one of the best home remedies to get rid of roaches naturally. Mix equal amounts of boric acid, flour, and sugar to make a dough. Set balls of dough around the home where cockroaches can feed on it. The flour and sugar will attract the roaches while the boric acid will kill them.
#2: Baking soda
A concoction of baking soda and sugar is an effective cockroach killer and controls the multiplication of these pests. Sugar acts as a bait to attract cockroaches and the baking soda will kill them. You just need to identify their hideouts and sprinkle this mixture in those corners.
Since their exoskeleton will be unable to expand, this can kill them. Roaches dislike the flavor and smell of baking soda, so add sugar to attract them. Baking soda and vinegar are ineffective, despite what internet rumors suggest. The vinegar will activate the baking soda too soon, and the smell will deter roaches.
Not only is peppermint oil a natural cockroach repellent—it's also toxic to roaches (and for the record, to bed bugs, too). The same Auburn University study found that mint oil killed both German and American cockroaches when they came into contact with it for an extended period.
Most roaches will move away from the smell of mothballs, and in rare cases, some roaches affected by the smell die due to inability to breath. In other words, we can say that mothballs mostly repel roaches, and in rare cases can kill them as well.
Household bleach is commonly used as a cleaning agent and gives off a strong smell that cockroaches hate. Filth and cleanliness don't mix at all, which makes the physical act of killing cockroaches with bleach very hard.
