Spectrum Lawn & Garden Insecticide



Spectrum 200SC Lawn Grub Insecticide is a liquid formulation for your lawn, protecting your lawn against African Black Beetle larvae and Billbug larvae as well as other insects.

The technical stuff

Spectrum 200SC works best when the target lawn grubs, like African Black Beetle larvae, are in their early stages of growth, so it’s critical to apply in early Spring before significant damage occurs.
Before you buy Spectrum 200 SC it probably makes sense to understand what the 200 and the SC stand for. It’s very common in professional products for their names to share with the user the concentration and the product formulation type and so the “200” stands for 200g/L Imidacloprid and the SC stands for suspension concentrate, this is a type of concentrate where the active is suspended in water.
At The Lawn Shed we love asking technical questions, so please feel free to contact us.

What is Spectrum 200SC insecticide good for?

It’s a powerful insecticide that is commonly used against the dreaded lawn grubs include African Black Beetle larvae and Argentinian Scarab. It is not just a lawn insecticide though and can be used in other areas of the garden, against common damaging insect pests like Aphids, Hibiscus Flower Beetle, Azalea Lace Bug, Psyllids, Mealybug, Soft Scales, Thrips, White Fly and Curl Grubs.

How to use Spectrum 200SC insecticide?

Spectrum 200SC insecticide needs to be applied to where the lawn grubs are doing the damage. Lawn grubs, like African black beetle larvae eat the roots of the lawn and therefore it needs to be applied to the lawn at the label rate (25ml/100m2) and then watered into the soil where the lawn grubs are. “Watering-in” can be done with a hose or sprinkler, but it’s best to setup a sprinkler and apply 12mm of irrigation. The best way to check for 12mm is to have a old tuna can on the lawn and once it fills up 1.2cm high you are good. The lawn grubs are beneath the surface so you won’t see them die but you should see the damage stop spreading.

What’s next

Well, that depends. If you’re applying Spectrum 200SC in a preventative fashion in September, then you’re all good. However, if you are applying after seeing some damage, then the lawn has probably taken taken a battering, the roots of sections are likely non-existent so it’s important to try and restore these. The best way to do this is with a restoring fertiliser like Lawn Play Renovate, while the roots are restoring themselves it’s important to keep the lawn nice and wet, without roots to draw up water you’ll need to help it out.

Q & A

How do I get the best results?

A nice even coverage of the lawn is critical and thorough watering in is the best way to achieve good results. The product is best applied before the insects get to big or become adults, that means an application before the first week of September.

How much water should I apply to water in?

Watering is required to get the product into the soil, this will require 12mm.

Is this safe for all turf types?

Absolutely and it even comes with an option to use on some garden plants for sucking insects like Aphids.

How long before I see results?

Spectrum kills the insects below the soil, so you won’t see them come to the surface but you will start to see your lawn recover.

Is it safe for kids and pets?

It’s best to allow the product to dry before walking on your lawn. Like most products keep the product container out of reach of children and pets.

Do I need to do anything else to keep my lawn looking good?

There’s a whole range of things you can do, the basics start with fertilising, weed control and insect protection. We have a great calendar and some great packs that help you solve all those problems in one go.
