1. Cure measures

Where the environmental sanitation is dirty and messy, cockroaches are rampant. Therefore, doing a good job in sanitation and managing the environment is a fundamental measure. To kill cockroaches indoors, we must first do a good job in hygiene and remove the habitat conditions of cockroaches, and extensively carry out the activities of plugging holes and plastering seams and "eight investigations" to remove the egg sheaths and cockroaches in the habitat of cockroaches. Cockroach marks refer to insect carcasses, residual limbs, bodies, wings, molting, cockroach excrement, empty egg sheaths and so on. "Eight checks" refer to: one check table, two check cabinets, three check chairs, four check ports (sewer ports), five check pools (washing pools), six check cases (food processing boards), seven check seams and eight check piles (coal piles, firewood piles and sundries piles). Cockroaches like to drill holes and hide cracks. Taking advantage of the living habit of pests, you can use putty, cement or silica gel to block gaps and caves, so that cockroaches have no hiding place. For those kitchens with seriously damaged internal walls and outdated furniture, it is necessary to thoroughly repair houses and update furniture in order to eliminate cockroaches.

2. Properly spray drugs to kill cockroaches

Cockroaches often inhabit and hide in cracks and holes, so when spraying drugs with a sprayer, it is necessary to spray drugs around cracks, holes and corners, so that the spraying effect is good and the drugs are saved. Cockroaches are reptiles, so don't spray them into the space, and you don't have to wear a mask. Spray them on all sides.

3. The trick of putting poison bait to kill cockroaches

Putting poison bait is a common and simple method to kill cockroaches, but if it is used properly, the trick is "less quantity, more points and wider area", that is, more poison points are put in a room, with less dosage at each point and wider distribution. In this way, cockroaches can eat poison bait when they climb out of their habitat, and the killing effect is obvious. In order to prevent poison bait from losing efficacy due to moisture, it is advisable to put poison erbium particles in bottle caps. Use powder strokes containing pesticides in cockroach activity places. Around the crevices, holes and corners where cockroaches inhabit and where they often move, the word "well" is used to make cockroaches poisoned by smeared powder marks when they go in and out. The painted road should not be too thin, but should be a thick line of 2-3 cm.

4. Move to a new house and don't forget to kill cockroaches

In recent years, urban buildings have sprung up like mushrooms after rain, and a large number of residents have moved into new houses. Warning to the public: When you move, please be sure to remove the cockroaches and their egg sheaths hidden in old furniture, clothes, books, cartons and wooden cases, otherwise, there will be cockroaches in the new house soon. Cockroaches can't fly. They spread by means of transportation and goods such as luggage, parcels and furniture, which leads to regional and even international spread.

There are also:

1. Fresh cucumbers repel cockroaches. Put fresh cucumbers in the cupboard, and cockroaches won't go near the cupboard. After fresh cucumber is put for two or three days, cut it and continue to smell cucumber, which can also effectively drive away cockroaches.

2. Fresh peach leaves repel cockroaches. Put the newly picked peach leaves in a place frequented by cockroaches, and the cockroaches will avoid them when they smell the smell of peach leaves.

3. Onions repel cockroaches. If you put a plate of sliced onion indoors, cockroaches will run away immediately when they smell it, and at the same time, they can delay the deterioration of other food indoors.
