To get rid of spiders, purchase an aerosol based on boric acid. They are still used to remove ants. Such aerosol needs to process the walls in the apartment, while do not forget to tightly close the windows and doors. The room should not be temporarily ventilated so that the room is saturated with an aerosol. The inhabitants of the apartment for some time should leave the room so as not to inhale caustic smells. Upon returning home, carry out wet cleaning in the house.
