To completely get rid of spiders in your home, you can take the following comprehensive measures:

Thorough cleaning: Spiders prefer to hang out and build webs in dusty, cluttered areas. Therefore, regularly clean every corner of your room, including the floor, walls, and ceiling, using a broom or vacuum cleaner to remove dust and spider webs. For hard-to-reach areas like corners and behind furniture, use a long-handled brush or a vacuum cleaner with an extension hose.

Tidy up your home: Tidy up your home to reduce the number of places spiders can hide. Clear away unnecessary items to keep your home clean and organized.

Check for gaps: Carefully check your home's windows, doors, vents, etc. for gaps. Spiders often enter the house through these gaps.

Seal gaps: Use sealant, tape, or other materials to seal gaps and prevent spiders from entering. Especially around windows, make sure they are well sealed to prevent spiders from crawling in from outside.

Essential oils: Peppermint, tea tree, lemon eucalyptus, and other essential oils can repel spiders. Place a drop of these oils on a cotton ball and place it in areas frequented by spiders, such as corners and windowsills. The strong smell will make spiders uncomfortable and keep them away.

Irritating foods: Garlic, onions and other foods with pungent smells can also be placed in the corner, which will have a certain effect in repelling spiders.

Reduce humidity: Spiders prefer humid environments, so lowering the humidity in your home can reduce their chances of survival. Use a dehumidifier or place desiccant in humid areas.

Clean up accumulated water: Clean up places where water easily accumulates, such as bathrooms and kitchens, in a timely manner to avoid the formation of a humid environment.

Install window screens: Installing window screens can prevent small insects such as mosquitoes from entering the room, thereby reducing the food source of spiders.

Clean your trash cans: Clean your trash cans regularly to avoid attracting flies and other insects.

Catching insects: For insects that have already appeared, you can use tools such as sticky insect boards to capture them to reduce the spider's food source.

Choose the right insecticide: If the above methods are ineffective, you can consider using chemical agents. However, be careful to choose an insecticide that is effective against spiders and safe for humans.

Use according to the instructions: When using insecticides, follow the instructions on the instructions and keep the room well ventilated to avoid harm to the human body.

Proper storage: Keep food, tableware and other items properly stored to prevent contamination by pesticides.
