Can Milk Be Used to Kill Pests? Effects and Detailed Usage Methods

Flowers & Gardening 0 views
Milk can indeed kill pests. When milk is sprayed onto the leaves, it coagulates on the leaf surface and forms a film. Smaller pests get stuck to this film. Once the milk has fully coagulated, rinse it under a tap and the pests will be washed away.

1. Can kill pests

Spraying milk onto plants can effectively kill pests. This is because milk coagulates on the leaves and forms a film. Smaller pests such as red spider mites and aphids get stuck to this film. Once the milk has fully coagulated, hold the plant under running water and rinse it, and the pests will be washed off.

2. Specific method

First prepare a carton of milk, then pour it into a spray bottle. After that, spray it onto the areas of the leaves where the pests are. Be careful to spray both the front and back of the leaves; if you only spray the front, pests on the back may remain on the leaves.

After spraying the milk, place the plant in a cool, well-ventilated spot and wait a few hours so that the milk on the leaves can coagulate. Finally, hold the plant under running water and rinse it, and all the small insects on the leaves will be washed off.
