Roaches are a die-hard insect specimen; tough, crafty and seemingly impervious to eradication attempts. Despite the best attempts of busy pest control companies, the roach remains a stubborn foe. Eliminating roaches is extremely difficult, but keeping them under control or at bay is definitely doable.
Coffee Grounds and Water
What makes this particular method so fantastic is that it's not only effective, it's absolutely non-toxic. This is of dire importance for those who have pets or small children roaming around. Fill a large glass jar about one quarter of the way with water. Inside the jar, place a small cup or glass that has been filled with moistened coffee grounds. Leave the jar opened and place it against a wall in your house.
The scent of the moist coffee grounds will draw the roaches in, but upon entering the jar, they will become trapped in the water and drown. Depending on the degree of your roach infestation, you may need to empty this jar trap and repeat the process every day.
The LifeSpy website recommends this recipe for a snack irresistible to roaches, but containing toxic boric acid. Mix 1/4 cup of shortening with 1/8 cup of sugar until smoothly combined. Next, mix in 1/2 cup of flour, 1/2 cup of chopped onion and 1 cup of boric acid. Add enough water to make a dough.
Wearing latex gloves, shape the mixture into balls, and leave the "treats" where cockroaches tend to infest, such as near water sources like sinks and toilets, inside cupboards, under refrigerators. The boric acid in the dough acts as a desiccant, killing the roach through dehydration. The boric acid method is not the best option for those with pets or small children.
Sugar And Baking Soda
Baking soda is predominately used as a rising agent in baking. The same properties that cause baking soda to act as a rising agent can be used to produce a sufficient enough degree of gas in a roach's stomach to kill it from the inside. The sugar draws the roach in.
Mix equal amounts of baking soda and sugar, and leave small piles of the mixture where the roaches have infested. Again, this will be dark areas where foodstuffs and crumbs are found, as well as water sources in the house. Roaches will feed on the sugar, and eventually die from extreme internal gastrointestinal distress. As with any homemade roach trap, results will not be seen immediately, but there will be a noticeable difference within days.
