What is the most effective way to get rid of cockroaches?

The most effective way to kill cockroaches is to buy drugs that poison cockroaches and put them in places where cockroaches often haunt.

Cockroaches, commonly known as cockroaches, are common medical insects, belonging to Arthropoda, Insecta and Cockroaches. Only dozens of species will invade people's homes, and several species will be kept as pets and become food for pets. Most of them can only be seen in barren hills and wild forests or insect museums.

The most common cockroaches at home are American cockroaches, Australian cockroaches and short-winged cockroaches, which are about 5.0 cm (1.97 inches) long. Small cockroaches include German cockroaches, Japanese cockroaches and Asian cockroaches, with a body length of about 1.5 cm (0.59 inch). Cockroaches in tropical areas are generally huge. Domestic cockroaches are generally nocturnal and photophobic, while wild cockroaches vary from species to species, with positive and negative phototaxis.

First of all, we should know how the cockroach got into the house, whether it existed in the room itself or flew in from the outside. In addition, if cockroaches enter from the outside and breed indoors (because cockroaches breed very fast), they should also be treated at the same time.

If it is from the outside, cockroaches have three ways to enter the room:

First, it climbed up from the sewer. If you don't have an odor-proof floor drain and the sewer pipe doesn't have a water seal, it may climb in from the sewer entrance at night. The solution to this situation is to carry out sewer maintenance and change it into an odor-resistant floor drain. Cockroaches can swim, even if they are thrown into the toilet, they can't drown.

Secondly, cockroaches can fly, and may fly directly into the room through the open window. So a wool pad (wool top) should be installed between the screen window and the screen window. This wool pad can perfectly block insects and ants that may crawl in. This thing is everywhere on the Internet, and it is very cheap. Including many mosquitoes, have evolved now, and many of them are useless with screens. Why? Because mosquitoes have evolved now, they don't fly in directly from the screen window, but slowly climb in through the gap of the screen window. I didn't expect that. It took me a long time to discover this rule.
