Turf Tips: Lawn Grubs
Lawn grubs love the warm weather, and the recent heat has seen them out in force. They are most active in South East Queensland from October until May, but found that they’ve been almost around nearly all year. This is why it’s important to stay especially vigilant as the weather warms up.
Signs of lawn grubs
Patchy lawns with brown or bare patches are the tell-tale signs of a lawn grub infestation. Other signs to keep an eye out for include white moths flying around as the sun goes down, white egg sacs on your house (eaves, fences, foliage, furniture) as well as an increase in lawn grub predators such as birds or orange/black wasps.
Preferring a healthy lawn, lawn grubs are far more likely to attack a well maintained lawn. This goes double for all forms of couch grass as they are more prone to infestation. While Sir Walter DNA Certified is more resilient to these pests and usually recovers quicker; it is still susceptible to attack.
Treating lawn grubs
A chemical free way to rid yourself of lawn grubs is to put a wet hessian bag over the affected area of your lawn. The grubs will attach themselves to the hessian overnight and you can then dispose of the grubs first thing in the morning.
The more thorough method for you can use a chemical like Grub Killa which you can purchase at your Local Bunnings Store. With the active ingredient Bifenthrin this product is toxic to most insects but less toxic to birds and of minimal toxicity to mammals. This makes it safer than many other pest control products.
Treating tips when spraying for lawn grubs
#1. Always spray in the late afternoon/evenings (Kill bugs at night, and weeds in the morning)
#2. Spray a second time 7-10 days later to break the lifecycle
#3. Don’t spray if rain is likely as you will only need to reapply
#4. Always read the label and follow label rates before application
#5. After treatment give any brown patches a hit with fertiliser and water to bring it back to life
Preventing lawn grubs
While products like Grub Killa will kill grubs that are currently in your lawn, there is a new product now available to the public to help with ongoing protection. You can prevent lawn grubs attacking by using a product called Acelepryn. Acelepryn targets a wide range of insect pests such as African Black Beetle, Argentinian Scarab, Bullbugs and several species of Caterpillars including Cutworm, Sod Webworm and Lawn Armyworm.
It is also unique in that it can be used as a preventative measure, with 3-6 months protection from every application. This means you can get year round protection from just 2 applications. This is a great solution for people with regular lawn grub invasions. Acelepryn is available to purchase from our head office at Acacia Ridge or from our online store to be directly delivered to your house.
