Tips for home insect repellent

If you want to get rid of bugs at home, you should start with environmental management, and use some physical and chemical control methods if necessary.

Clean frequently

Household pests are mainly cereal pests and storage pests.

• Rice bugs , cockroaches and other grain pests:

mainly hide in rice jars, flour bags, cabinets and other food containers. Dead spots such as kitchens and bathrooms must be cleaned regularly. Seal flour, sugar and other ingredients; do not leave food overnight and dispose of garbage promptly.

• Ants, mites and other storage pests:

often appear in closed environments such as closets and attics. Pay attention to turning them regularly, drying them frequently, and shaking them. The water storage corners in the bathroom should be kept dry, and the accumulated water in flower pots, vases, floor drains, etc. should be cleaned promptly.

Hot water boiling

Items that come into direct contact with people, such as rags, tableware, kitchen utensils, etc., can be steamed at high temperatures. Even some dishes and chopsticks that are not used frequently should be cleaned frequently to avoid contamination with each other.

It is recommended to clean clothes that have not been worn for a long time, as well as frequently touched household items such as sofa covers, carpets, towels, etc. at least once a month.

Ventilate frequently

When cleaning sofas, mattresses or carpets, a large number of hidden bacteria, dust mites , and dander will also float in the air. At this time, it is best to wear a mask and ensure ventilation by opening windows.

Keep in mind the 368 principle

Adopt the "368 principle" of "block three holes, seal six seams, and check eight holes":

Block three holes: block the holes through which pipes such as water pipes, gas pipes , and heating pipes pass.

Seal six seams: Use putty , cement and other materials to block and seal the holes and gaps in walls, floors, door frames, window sills (frames), pools and sewers.

Eight searches: Check tables, cabinets, chairs, mouths (sewer outlets), pools (sinks), cases (kitchen chopping boards), seams, and piles (pile of debris).

Use less medication

It is not recommended to use a large amount of medication when removing pests, but if there are still bugs after treatment, you can use appropriate medication.

For example, in places where cockroaches are often found, such as kitchens and bathrooms, the principle of "small quantity, large number, and wide coverage" is used, and the focus is on putting cockroach-killing bait.

When spraying insecticides, try to spray the agent on the walls, gaps, and corners instead of in the air to reduce harm to the human body. ▲
