Two methods to eliminate insects and ants in flower pots

① When small flying insects appear in a flower pot, you can use three or four cotton swabs (cotton sticks), soak them thoroughly with dichlorvos, to the extent that it does not drip, then insert the handle ends into the potting soil around the plant, and the flying insects can be eliminated.

② When ants appear in a flower pot, you can soak cigarette butts and cut tobacco in hot water for one or two days. When the water turns dark brown, sprinkle part of the water on the flower stems and leaves, and after diluting the rest, pour it into the flower pot, and the ants can be eliminated.
