How do I control Grasshoppers On Cannabis?


Grasshoppers and caterpillars are two main pests that cause damage to plants. Dealing with these pests effectively and safely is essential in maintaining a thriving garden or crop field. This article will discuss various methods to repel and control grasshoppers, including passive repellants, homemade mixtures, and chemical control.

Passive Repellants​

If grasshoppers are causing significant damage to your plants, try placing a few dead ones on your plants in plain view. This can deter other grasshoppers from approaching. You can also smash up some fresh cloves of garlic and spread them around your plants, as garlic is a natural grasshopper repellant. Mothballs may also work, as they seem to repel various critters.

A fine mesh around your plants can help keep grasshoppers out while allowing light, air, and rain to pass through. Be sure to remove the mesh when watering or feeding your plants and raise it higher as your plants grow. Note that this method may not be suitable for stealth gardens.

Homemade Mixture​

Prepare a homemade mixture by combining water, crushed garlic, hot peppers, and other repulsive ingredients in a big pot. Bring the mixture to a boil, let it sit for a few days, and occasionally stir. Strain the liquid into a spray bottle and spray your plants two or three times a week, as well as after rainfall. Avoid spraying the bud sites later in the season. While this method is effective against grasshoppers, it may attract ants.

Chemical Control​

If grasshoppers persist, consider using chemical control methods like diazinon or similar poisons. Be cautious not to spray the bud sites, as this may result in harmful chemicals entering your plants. Some chemicals can be "puffed" onto your plants, but they may clump and cause mold after exposure to dew or rain.

Natural Enemies​

Grasshoppers have natural enemies, including beetles, birds, mice, snakes, and spiders. Encouraging these predators in your garden can help control grasshopper populations.

Bait Recipe​

A bait recipe that can help control grasshoppers includes mixing 7 pints of water, 1 pint of liquid Sevin % Dust, 1 pint of molasses, and 10 pints of wheat germ. Form the mixture into a dough-like substance and roll it into balls to place around your plants. The grasshoppers will be attracted to the bait and ultimately be killed by the Sevin insecticide.


Early treatment and prevention are the most effective ways to deal with grasshopper damage. By using a combination of passive repellants, homemade mixtures, chemical control methods, and natural predators, you can protect your plants and maintain a healthy garden or crop field.
