Grubs, or young beetles in their larval stage, are soft, C-shaped insects that live in soil or decaying and rotting plants. Since they breed in the soil, they are closest to the roots and feed on them, causing much damage. For instance, grub infestation causes the grass to start to dry up and the lawn to become brown and patchy quickly. Fortunately, there are a few natural ways to get rid of grubs.
How to get rid of grubs naturally
Since the grubs attack the root of the lawn grass, it begins to uproot from the soil, and brown patches begin to show through. Another way to tell that the lawn is infested with grubs is when one starts to notice a flock of birds perched on the lawn and pecking at the soil looking for larvae to feed on.
If one does not want to use chemical pesticides or repellants, they can consider a few tips to naturally get rid of grubs.
1. Avoid overwatering
Many homeowners unintentionally overwater their lawns, which can become breeding grounds for pests like grubs. One should look up the type of grass that majorly grows and understand how much and how frequently they should water the lawn. Some types of grass require frequent watering, while some start to rot because of overwatering.
2. Hang bird feeders to attract birds
One can consider hanging bird feeders and birdhouses around the lawn to attract birds, as they love feeding on grubs. That said, some birds may damage the grass while they tread on it. So, it is essential to overseed a lawn to regrow damaged grass. One can also allow chickens on their lawn for a limited time, as they feed on grubs as well.
3. Aerate the lawn regularly
Aerating is the process of digging up small holes in the lawn to improve drainage and air circulation. Periodically aerating reduces the risk of grubs settling in the roots and causing damage.
4. Dethatch regularly
The dried grass, roots, and other plant debris from a lawn may settle between the turf and soil. These become beetle breeding grounds, where eggs become larvae and grubs. Regularly dethatching removes all the dried waste. Without such organic waste and easy nesting grounds, beetles cannot breed or lay eggs in the soil close to the grassroots.
5. Allow moles and raccoons temporarily
Most homeowners install barriers or erect noise machines and ultrasound devices to deter moles and raccoons from entering their yards. That said, one should turn off these devices temporarily when they notice grub infestation. This is because moles and raccoons love insects and grubs. They might damage the lawn a bit, but they will also ensure it is rid of grub infestation. Once the grub infestation is clear, one can activate the mechanisms again.
6. Spray neem oil
Consider spraying neem oil during the egg-laying season. The strong and bitter scent of the neem will deter the adult beetles from laying eggs in the lawn grass.
7. Use beneficial nematodes
Microorganisms known as beneficial nematodes, invisible to the human eye, have proven effective in eliminating agricultural pests. These are available in nurseries, retail, and online stores. Look for beneficial nematodes that can kill grubs and apply them as instructed. They are typically mixed with water and sprayed on the lawn in the early morning or late evening.
Since grubs appear frequently and multiple times a year, one may find it cumbersome and expensive to apply the treatments repeatedly. Some DIY ideas can help get rid of grubs instantly. Borax, for instance, though a chemical, is natural and safe for the environment. Mix a tablespoon of borax in warm water and sprinkle it on the grub-infected areas. Don’t use concentrated borax or too much of it, as it can be counterproductive.
Milky spores can also be beneficial. These are natural bacteria available in powder and granular form. Spread the milky spore across the affected areas. Use protective gear like goggles, masks, and gloves, as the bacteria can irritate. Spread the powder and granule only when there is no wind, as it does not travel to adjacent properties. Milky spores can be effective for many years.
How to get rid of grubs in 24 hours
Chemical treatment solutions can help get rid of grubs within 24 hours. One should closely monitor the growth of their lawn grass and observe seasonal changes to anticipate potential grub infestations. They should then take preventative measures or take action to get rid of existing infestations, such as spraying the treatment solutions.
Best seasons for killing grubs in the lawn
Once the grubs appear, they stay as larvae and then as a beetle for one year at least. Some beetles can stay alive for up to three years. One should use preventive and curative measures to prevent adult beetles from laying eggs or killing the grub once they hatch. The best season for preventive treatment is from spring to early summer. Curative treatments, on the other hand, can be applied when the grubs begin to appear in the later summer to early fall, between August and September. Experts generally agree that the best time to apply the suitable treatment is between late summer and early fall.
