As lawn lovers, there is nothing worse than seeing imperfection in your beautifully manicured lawn. While weeds are certainly annoying, it’s lawn grubs that can do enough damage to bring your yard to its knees.
So, how to control lawn grubs in your lawn? Correct treatment begins by finding and identifying the lawn grubs that are doing the damage, thus allowing us to use the proper treatment.
How to Identify Signs of Lawn Grubs
It’s time to go scouting. After all, every good lawn is that way because we maintain a watchful eye over its condition.
In fact, there’s a good chance you’re here because you’ve already seen some of the tell-tale signs of insect damage.
The most common signs from African Black beetle larvae include:
- Bird damage- as they strip out your lawn looking for their next meal
- Yellow spotty patches, where the turf pulls straight out
(Remember for African Black beetle larvae you will need to use Acelepryn)
The most common signs from Lawn Armyworm include:
- Lawn that has been stripped of leaves
- Brown patches that are widening fast
Where to Find Lawn Grubs in Your Lawn
Now you know the signs, let’s see if we can find the lawn grub that’s doing damage to your lawn. The best place to start is at the edge of the damaged patch.
Look for signs and symptoms such as turf pulling straight out or those stripped leaves. Once you’ve looked for the signs of insect damage, the next step is to try and bring some lawn grubs to the surface. We do this by creating an irritating environment below the surface (in the thatch and soil) that the lawn grubs don’t enjoy, forcing them to come to the surface where we can find them.
The easiest way to do this is by applying dishwashing detergent to an area of suspected damage. Simply add 30ml of dishwashing detergent to a 9L watering can and apply over a 1m2 area (buckets work just as well). Give it a few minutes, and the lawn grub should come to the surface. This method works particularly well for lawn grubs like Lawn Armyworms, which are thatch dwellers.
Another fun way to identify pests is to go out looking at night, Lawn Armyworms are very active at night and are found crawling along the surface, and if you catch them in the act, you know what pest you have.
A commonly recommended identification technique is to trick the lawn grubs into believing they are hiding. Simply leave a damp towel out overnight, and lawn grubs like Lawn Armyworm will hide here thinking they are safe from the heat of the day, birds, but they won’t be safe from you.
These methods are a great place to start when looking for lawn grubs because they’re not destructive to the surface. Sadly, pests like African black beetle larvae, sometimes referred to as white grubs or curl grubs, are deeper dwelling, especially early in the season (September to December). This means they may not be found with the above methods.
So, if you still haven’t found your lawn grubs and you aren’t sure what pest you have, then a destructive method is a great way to find them. This simply involves digging up an area that has the damage with a spade and looking for the lawn grubs amongst the roots and soil.
Just a word of warning, we often see people claiming to have lawn grubs after birds are seen tearing up their lawn. While birds ripping at your lawn can be a sign of lawn grubs, they also love to eat fleshy rhizomes, particularly of Kikuyu, so only use the sight of birds as a reason to further inspect your lawn, not a reason to treat.
