If I spray insecticide through the crack in the door, will the cockroaches still enter the room?

You spray insecticide into the crack of the door. Do cockroaches still enter the room, you ask? I think. You can only stop cockroaches. Go through the crack in the door. But there are other channels for cockroaches. Enter your room.

Insecticide was sprayed at the door. But. His.

Other larval adults. Because I have already hidden your room, so. Almost.

Pesticides do not have a killing effect on him. So cockroaches will still be in your room.

There are also cockroaches that can be hidden. Sewer. Damp and dark places such as kitchens.

And these are the places you tend to be. There is no way to use pesticides for fear of causing food to your house. Contaminate.

As long as there are cockroaches alive here. There is no nature sprayed by pesticides. You won't be able to kill all the cockroaches in your room.

So they'll show up in your room from time to time. Causes you trouble.

When your power is not enough to kill you. Cockroaches indoors at the time. Then you can spend money to hire a professional sanitizing company.

Perform a comprehensive extermination and inactivation of all areas in your room where cockroaches may be present. Strive to remove all cockroach adult larvae including eggs. All for you.

Kill it. Although it cost a little money. But.

It can basically exterminate all the cockroaches in your indoor room at once. I think it's still worth it.

It will also enter the room, cockroaches are everywhere, insecticide spray has no effect after a long time, cockroaches have strong vitality, everywhere, all the time.

Cockroaches evolve faster than humans, and you can't kill it because even if you cut off the cockroach's head, it can live for 7 days, which is why it dies because it has no head to eat and is hungry.

Cockroaches are even more awesome than human evolution, you can't kill him, because even if a cockroach is cut off by you, he can survive for 7 days, and the reason why he died is because he has no head to eat and starves to death.

Insecticide is a contact type of cockroach control product. The insecticide is sprayed in the air, and the cockroach body will be poisoned and die when it comes into contact with the insecticide floating in the air. Therefore, cockroaches are more sensitive to pesticides, and when they find insecticides in the air, they will find a safe place to hide them so as not to be killed by pesticides.

In this case, the cockroach panicked and accidentally ran out.

Ways to repel cockroaches:1. Cockroaches need water to survive.

They can go 1 month without food (depending on temperature and size), but they cannot survive more than 1 week without water. Find out all the leaks in the house and fix them one by one. After cutting off the cockroaches' water supply, they will be more interested in the gelatinous bait you have set up.

2. Clean the house.

The most critical step in preventing cockroaches is to keep it clean. Start in the kitchen. Wash the dishes immediately after eating and remove the food. Clean up food crumbs and spills right away and keep them basic. Pay special attention to cleaning the top of the stove, as cockroaches love grease.

3. Seal the container with the food and don't leave the food outside for too long.

Don't leave dirty dishes until the next day, and don't put fruit on the table.

After the cockroach is stained with insecticide, the insecticide will enter the cockroach's body through **, act on the acetylcholine receptor, and make the cockroach in a state of excitement through a series of reactions, if the drug is enough, it will die after a period of time. If you think cockroaches are dying everywhere, you can use a cockroach house and cockroach bait.

It's embarrassing to ask, the dying struggle and running out for fresh air.

Spraying insecticides during the day can kill cockroaches, but the effect is limited. Cockroaches like to hide in dark corners during the day and go out at night, so spraying at night is generally more effective than during the day. After eating at night, you can put away all the tableware and kitchen utensils, then spray insecticide, close the doors and windows after spraying, leave the house, and open the windows for ventilation after 3 hours.

1. Food trapping

Put a small amount of bait in the trap (which can be made from canned bottles or loofahs), such as rice grains, biscuits, brown sugar, etc., and place them in the frequent spots of cockroaches before their nocturnal activities, and collect and kill them the next morning.

Second, boiling water scalding

1. Pour boiling water into the corners, holes, and crevices where cockroaches are hiding, which can have a scalding effect.

2. When the temperature exceeds 60, the cockroach will die within a few minutes, and the eggs in the egg pod will also be inactivated.

3. Plugging and exterminating cockroaches

1. For cockroaches living in hidden places, lime and sticky soil can be used to plug the gaps, so that they can not crawl out and starve to death (and may also inhibit the hatching of egg pods).

2. The blockage work should be carried out during the day, because at night cockroaches will go out, and the blockage will cause them to wander around because they cannot return to the hidden place.

Fourth, poison bait killing

Sprinkle some laundry detergent on top of watermelon or apple peel and place it in a corner to find the poisoned cockroaches in a few days.

5. Use baking soda

Put the sugar and baking soda in a bowl in a 1:1 ratio, mix well and put it in a corner, the sugar can attract cockroaches, and the alkaline gas produced by baking soda can kill cockroaches.

Sixth, low temperature killing

When the outside temperature drops to minus 5-10, move the furniture and items containing cockroaches outdoors and leave them for about half an hour to freeze to death.

There are a lot of cockroaches in the kitchen tells you a very simple way to get rid of cockroaches in the kitchen.

Insecticides can be used in the kitchen, but they should be used sparingly, and then remember to open the window for ventilation after use, otherwise they will be poisoned and other hazards together. At the same time, do not touch the utensils when spraying insecticides, otherwise harmful ingredients will remain.

Of course, you can use insecticides directly, but I don't think the effect is particularly obvious, and I personally recommend buying the kind of cockroach killing medicine, which may be better.

Of course, insecticides can be used directly, which has a huge killing effect on cockroaches and can be eliminated in one day.

Cockroaches are pervasive, as long as they see the gaps, they can survive, especially like humid and warm places, especially the kitchen at home with the most cockroaches, I believe that many girls are afraid of cockroaches, and cockroaches at home must not be stepped on, we prepare a small bowl, pour an appropriate amount of sugar and baking soda into the bowl in turn, and then pour in a spoonful or so of laundry detergent.

Fresh cucumbers repel cockroaches. Put fresh cucumbers in the pantry so that cockroaches won't get close to the pantry. After two or three days of fresh cucumber, cut it and continue to emit the smell of cucumber, which can also effectively repel cockroaches; Fresh peach leaves repel cockroaches.

I heard from a friend that washing powder can kill cockroaches, so I poured some laundry detergent on the walls of the kitchen, bedroom, and bathroom. After a month, there were no cockroaches in sight. It's just that cleaning is not good at cleaning.

The above is a personal experience, I hope it will be helpful to you, thank you. Do not give it an environment to survive.
