Whitefly & How To Deal With Them

So What Are Whitefly?

Whitefly are a very common pest that you’ll find in your grow room, and when left untreated, they can destroy your crop. We’ll give you some tips on how to spot them before they wreak havoc, how to get rid of them, and some useful aftercare for your plants.

If you’re looking for signs of whitefly, it’s a good idea to check the underside of your leaves, this is where they normally lay their eggs. If you spot whitefly eggs, you’ve normally got around a week before they hatch into nymphs. When they’re in their adult form, it’s quite hard to miss them as they usually stand out from the leaves.

Why Are Whitefly Such a Pain?

The reason Whitefly are such a danger to your crop is the fact that they consume the nutrients within your plants. This has an obvious affect on your plants as it can stunt growth and damage their leaves, further affecting the plants ability to photosynthesise. When they consume the nutrients, the excrete them as a sweet and sticky substance, which is another way to spot them on your plants.

So How Do We Control Whitefly?

The best way to control them is with a product such as Guard ‘n’ Aid. It uses an all-around natural insecticide known as Pyrethrum. Pyrethrum is an oil based natural insecticide made from the dried flower heads of Chrysanthemum and targets the respiratory organ and nervous system of insects. It’s effective in combating and controlling eggs, larvae and adult stages of insects such as including White fly.

(It’s also fantastic against Aphids, Thrips, Mites, Scale Bugs, Wool Bug, Mealy Bug, Beetles and Caterpillars.)

What Else Can You Do to Protect Against Whitefly?

Plants are like people, after they’ve been feeling a little under the weather, they need some TLC.  We recommend looking after them with CannaCure. When sprayed onto plant leaves, CannaCure makes a natural, biodegradable and environmentally friendly second skin which is flexible, and which still allows the plant to breathe (transpire) normally. The second skin prevents pests and mildew spores from making direct contact with the plant leaf and stops any leftover pests from feeding on your leaves.


After you’ve completed these steps, it’s also a good idea to trim any damaged leaves and dispose of them. Also, keep an eye out for any leftover eggs that could possibly be on your leaves and trim those too.

The best thing to do with any pest is to spot them before they have chance to hatch / repopulate your plants, so giving you plants a check over every day is going to make dealing with pests a lot easier.
