Cockroaches are a common household nuisance, and many seek effective ways to eliminate them before they infest homes. Here’s a simple yet ingenious method to tackle these pests.

The solution requires minimal ingredients: one egg yolk and 25–40 grams of boric acid powder, available at veterinary pharmacies.

Ingredients for cockroach elimination: Boric acid and egg yolk.

Mix the two ingredients until the mixture thickens. Shape it into small balls (about the size of a golf ball) and let them dry for an hour. Place these balls in hidden corners, shelves, cabinets, and areas where cockroaches frequent.

The results will surprise you. Cockroaches, attracted by the scent, will consume the bait. However, the boric acid will expand in their digestive system, leading to their demise.

Initially, it may seem like the cockroaches ignore the bait, but after three weeks, you’ll notice a significant daily reduction in their numbers.

Caution:

Boric acid is a weak acid but highly toxic when used in pesticides. Never ingest it, and store it securely, out of reach of children and pets.

Additional quick and simple cockroach elimination methods include:

1. Cucumber

Place a cucumber slice in kitchen cabinets or food storage areas. Cockroaches will avoid the area. Replace or cut the cucumber lengthwise if the scent fades.

2. Perilla

Mix perilla leaves and sugar in a 1:1 ratio, grind into a powder, and place in cockroach-prone areas. This American household tip eliminates cockroaches within 3–14 days.

3. Onion

Place a sliced onion on a plate in food cabinets. The strong scent will repel cockroaches instantly.

Cockroaches detest the pungent smell of onions.

4. Orange and Lemon Peel

Dry orange and lemon peels, place them in kitchen cabinets, or burn the dried peels. This not only leaves a pleasant aroma but also effectively repels cockroaches.

5. Alum

Dissolve alum in hot water, dip a cloth in the solution, and wipe the floors. Once dry, the crystallized alum will penetrate floor cracks, repelling both cockroaches and ants.

6. Bay Leaves

Crush bay leaves, mix with water, and wipe kitchen cabinets. This simple method ensures cockroaches disappear without a trace.

7. Soapy Water

Mix soap with water in a spray bottle. Spray directly on cockroaches or their nests for a non-toxic, effective solution.
