  • Use it once a week for better prevention. If your plants have severe pest issues, then spray garlic water twice a week or whenever you see pests.
  • During rain, when plants get wet, re-apply the solution. Do this after every time you water the plants too.

Benefits of Using Garlic Water Pesticide for Plants

Garlic is completely organic and safe for both plants and you. According to the Environmental Protection Agency, contact with certain toxic pesticides has a potential health risk, and using garlic water as a pesticide prevents exposure to them.

It is also effective against bean beetles, whiteflies, aphids, Colorado potato beetles, spider mites, moths, ants, termites, and cabbage worms while keeping the beneficial bugs safe. You can use garlic water solution as a soil treatment for fungus gnats and nematodes too.

Some Preventive Measures

Though garlic water is non-toxic, it can be an irritant, mainly to the eyes. It is a good idea to wear gloves while using the solution. Always keep the nozzle of the spray bottle away from your face. After spraying the solution, keep your kids and pets away from the plants.

Also, store the un-used solution in the refrigerator to save it from rotting.
