What Are Common Signs of Lawn Pests?
If you suspect that your lawn is under attack from a pest invasion, there are a few common signs to look for:
- Increased bird activity
- Growing brown patches in your lawn
- Increased moth activity around your lawn
What Are Lawn Grubs, and Do I Need to Remove Them?
Lawn Grubs, also known as African Black Beetles, have 4 common stages in their lifecycle: egg, grub, pupae, and adult. These pests will be active from September through to March.
Key identifying features of Lawn Grubs:
- Pale cream/white body
- Orange/yellow/brown head
- 15mm to 60mm in length

If you are only seeing a small number of grubs in your lawn and there is no visible damage, it is best to keep an eye on your lawn over the coming weeks and monitor for any changes in the lawn’s health.
If you do notice that damage is occurring, or there is a large amount of grubs present, we then recommend stepping in and using an insecticide for treatment. When it comes to product options, we recommend using Battle Insecticide. This will provide a quick and effective knockdown.

What Are Common Signs of Armyworm?
If damage has rapidly occurred over your lawn over a span of a few days, your lawn may be facing an invasion from Armyworm. Armyworm is mostly present around spring, summer, and early autumn.
Key identifying features of Armyworm:
- 2mm to 40mm in length
- Three parallel white or cream stripes along their body
- Stripes paired with black spots along its body

If you do spot one armyworm in your lawn, it is best to act quickly, as one caterpillar can lay more than 1,000 eggs within 4-10 days. Therefore, getting on top of an infestation quickly is key.
If you do happen to have Armyworms in your lawn, we recommend applying a fast-acting insecticide like Battle Insecticide or Baythroid Advanced as soon as you can to help prevent further damage. To ensure you are treating the entire lifecycle, we recommend a follow-up application 10-14 days after your initial treatment.
How Can I Prevent Armyworm and Lawn Grubs?
As pest pressures continue to rise over the coming weeks, it is important to note that there is a way to help prevent Armyworm and Lawn Grub attacks entirely. Acelepryn-based products like Grub Guard Ultimate 4kg, will provide up to 6 months of protection from these damage-causing insects on your lawn. So, for seasonal protection, apply every 6 months.

Do I Need to Be Concerned About Mole Crickets in My Lawn?
Mole Crickets are another type of lawn pest to keep your eye out for. These crickets mostly spend the majority of their lives underneath the soil and are primarily nocturnal animals.
Key identifying features of Mole Crickets:
- 30 mm to 40 mm in length
- Shovel-like claws, which provide efficient burrowing abilities
- Short back legs, ideal for pushing dirt
- 2 fine antennae on their face

If you do happen to find a small number of Mole Crickets in your lawn, this will generally not be a cause for concern. However, if they are causing damage to the lawn or are present in large numbers, you may need to act.
To remove Mole Crickets, we recommend using a fast-acting insecticide. For treatment, it is best to use either a Fipronil or Bifenthrin-based product. Battle Insecticide (Bifenthrin) is a great option.
Can Couch Mites Damage My Lawn?
Although these pests are not quite as common, Couch Mites are another lawn pest to keep your eye out for.
Couch Mites are a tiny, microscopic pest that can affect your lawn’s growth habit. One of the main signs that a lawn has been impacted by Couch Mite is that it will affect the growing point of the leaf, causing severe stunting and yellowing of the leaf. This causes the turf’s leaves to look like a “witches’ broom”. Although these mites will usually attack couch grasses, they can still appear in other warm-season turf types.

If your lawn is experiencing Couch Mite damage, it is recommended to use a miticide like Agador for treatment. You can find more information on how to best remove Couch Mites here.
Do Ants Cause Damage to Lawns?
Ants are an important animal to have in your garden’s ecosystem. They can help aerate soil, provide natural pest control, and help move organic matter within the soil profile. Due to these benefits, they are generally not considered to be a pest unless they are present in large infestations.
If your lawn does have a particularly large infestation, or damage has started to occur, you may want to look at removing them.
How to identify ant infestations:
- Significant number of ant mounds
- Dead and dry patches in the lawn with small holes nearby

When treating an active ant infestation, using a Fipronil or Bifenthrin-based insecticide, like Battle Insecticide is recommended.
