According to Associate Professor Hsu Er-lie, Faculty of entomology, National University of Taiwan (China), spray only has the effect of quickly killing cockroaches that appear before the eyes, but cannot kill the Larvae and eggs of cockroaches in hiding.
Meanwhile, the locust reduction method is based on the habit of living with the flock of locust. When a cockroach eats a feeding ball, it will die after about 4-5 days. During this time, its droppings and carcasses still contain toxins. Other cockroaches that eat them will continue to be poisoned, creating a chain effect, helping to destroy the herd.
Preventing cockroaches from entering the water pipe
In addition to killing cockroaches, preventing cockroaches from entering the house is a very important step. Some folk tips such as using the scent of basil, garlic, chili, lemon peel or moping with boric acid water are spread online, but these methods are not effective because the concentration is too low, making it difficult to catch cockroaches.
The most correct and effective way is to close the entrances that the locust can enter: fill the gaps in the entrances and windows, and immediately repair damaged areas.
Install a filter or cover for drainage holes when not in use. Drainage is a place where cockroaches can easily hide and move. If you do not have a suitable cover, you can use a plastic bag to fill with water, tie it tightly and place it in the sewer mouth to temporarily block the cockroaches.
Eliminate the living environment of cockroaches
Keeping your home neat and clean, avoiding old newspaper piles, cartons and scraps are an important way to keep your roosters from having a shelter.
If necessary, keep them, place a locust around them. Dry the carton in the sun when the weather is favorable. These measures help limit the risk of pests breeding and penetrating into the living space.
Cutting off the food source for cockroaches
To prevent cockroaches from eating and drinking, you can use the following methods:
After finishing, pour leftover food into the plastic bags, tie tightly to the mouths of the bags and cover the trash can. A dirty bowl of dishes must be washed immediately.
After finishing, clean thoroughly, do not leave left leftovers on the floor, table or chair. The food was not yet eaten, so it was sealed.
You should regularly clean sewers in the kitchen and bathroom, and clean the drainage pipes periodically, because grease is a food source for cockroaches.
Keep the kitchen clean and avoid stagnant water. Keep the room dry to reduce the moisture needed for the survival and reproduction of cockroaches.
