Home Remedy to Kill Grubs


As lawns sprout lush and green in the spring and summer months, they can attract a lot of attention, both good and bad. Your lawn may be the envy of your neighbors, but it may also attract grubs. These nasty pests will leave large brown patches on your lawn as they eat the roots of the grass; they can also attract moles and other animals that can dig up your soil. While pesticides are effective against grubs, you may want to try a less harmful approach; there are a couple of environmentally friendly products you can try at your own home.

Things You'll Need

  • Garden plants
  • 2 tbsp. neem oil
  • Water
  • Garden sprayer
  • Milky spore powder
  • Add trees and plants to your lawn or garden that are known to attract birds and other bug-eaters. As the population of predators grows, the population of grubs will shrink.

  • Mix 2 tbsp. neem oil into one gallon of water. Neem oil is environmentally safe because it will only affect grubs and beetles.

  • Add the mixture to a garden sprayer and spray your lawn so that the soil is soaked with the oil. As the grubs chew on the grass roots and dig through the soil, the neem oil will kill the bugs.

  • Apply milky spore to your garden; the spore comes in a powder form. Spread it evenly across your lawn so that it soaks into your soil. Milky spore is a disease that kills only grubs; it will spread from grub to grub, eliminating the infestation.

Tips & Warnings

  • Find neem oil, milky spore, and other lawn supplies at garden centers and nurseries. Consult experts at these centers regarding types of plants that will attract birds and other predators.
  • Treat grubs in late summer and early fall, when the grubs have recently hatched and are feeding extensively to get larger. Feeding is key to the spread of many of these home remedies.
  • Milky spore can take 2 to 3 years to completely integrate into your lawn and start to kill the grubs, so use it only in conjunction with other grub-killing efforts. Once it absorbs, however, milky spore can last for up to 20 years.
