Essential Oils

  • Peppermint Oil

Peppermint oil is not only repellent to animals like rats but also cockroaches. Undiluted peppermint oil can be tricky at times. Attempt mixing ten drops of the oil with a quart of water and spray it in your yard, especially places where you feel cockroaches reside.

  • Catnip oil

What is it about cockroaches and night time? Are cockroaches charmed to light or repelled by it? And, how can you aid to eliminate cockroaches and keep them away?

Well, almost every cockroach is nocturnal, which indicates they are just active at night. Thus, are cockroaches attracted to light? The answer is no.

Not only that, cockroach does not like or cherish artificial light; they are also not fond of natural light either. As a result of this, you are very unlikely to see cockroaches during the day. Assuming that you do observe a cockroach during the day, it may be as a result that the cockroach got crowded out of its territory or was forced out of hiding because it has no food.

Sighting a cockroach when the sun has not come up indicates that you may have an infestation. Nevertheless, after a short time, cockroaches can adapt to their environment and become acclimated to light.

But what if you only notice one cockroach at night? Does that indicate it was just a scoundrel roach that wandered in? It is possible, but also not likely. Cockroaches are aggressive breeders: thus, their populations can multiply faster.

A general rule of thumb, when you notice a single cockroach, there are likely many others in the surrounding.


We might feel cockroaches love or cherish sugar. Well, you are right. Cockroaches will be so happy if you choose to leave cakes, fruits, candy, and juice with high sugar content lying not covered around.

The Pest control businesses discovered it in the 1980s. They noticed that sprinkling sugar in a particular area would leave cockroaches milling around in no time. These pest control businesses used to their merit and began to bait cockroaches with glucose laced with insecticide. The meal eliminated them as they returned to their homes.

Baking soda and sugar are some of the things that repel cockroaches

Other roaches usually consume the remains of the dead, which is not astonishing since these creatures will eat almost anything. The scavenging insects also got eliminated as the bodies of the dead cockroaches still contained the poison.

This went for an extended period until they (cockroaches) discovered that sugar was killing them. Then they started to resist this sugar. Their senses rapidly adjusted to spot sweet sugar as bitter.

Various pest control businesses found that, too, and changed the glucose with fructose, another type of sugar. The cockroaches were smart also and began avoiding fructose as well.

Scientists traced this astonishing switch to many decades ago when cockroaches first developed the ability to spot sweet but dangerous parts of individual plants they consumed as bitter. That particular skill was hereditarily suppressed when they began to stay around humans and only returned when humans began to poison their food.

Humans touching them

According to recent research, cockroaches hate it when humans touch them. In other words, they can even flee to begin cleaning themselves of the contact they had with the human being. But you should also note that cockroaches do not only like humans touching them, but anything else moving them because they feel that simple contact can cause harm to their existence.

To be clear on this, just as we hate contacting cockroaches, the cockroaches also hate when they reach humans. If you notice in your homes, they usually flee from more massive creatures, be it human or not, because they know that any contact with the gigantic creature might result in death.

Contact with almost any organism could leave a few residues on the roach that could be unfavorable to its survival. When it concerns humans, it is the natural oils that we unintentionally leave on anything we have contact with. That particular oil could interrupt how the cockroach’s body operates.


So we had an investigative series to review if Mothballs actually do repel roachesso the result was positive. This is why we added mothballs as part of the things cockroaches hate. Just like moths, cockroaches hate the smell of mothballs – which you can take advantage of in your home. You can achieve this by placing mothballs strategically in places like under the kitchen cabinet, furniture cushions, stove, and the kitchen sink. Make the mothball doesn’t come in contact with water.


The majority of the affected are the antennae. They may appear unremarkable to us, but they are essential for their survival. The antennae operate as the creature’s nose and are needed for perceiving food and finding possible mates. Those oils and other factors we’ve listed out will lower the pest’s capacity to view, which is not suitable for the cockroach.
