The Best Pest Control

Spot Them and Deal With Them!

It’s been an unusually wet start to the year in the UK. There were flash floods and fluctuating temperatures well into April.

This certainly meant that (through Spring at least) growers were pestered by pests. As Summer is around the corner and it’s starting to get warmer, they will surely be still making an appearance!
 
Dealing with growroom and greenhouse pests can be overwhelming. If an infestation gets really nasty, crop damage can be severe. Many pests target young, fresh growth – buds and shoots – so the potential for damage in terms of yield cannot be overstated.

The best advice we can offer growers is this: don’t leave it a couple of days between noticing any of these pests, and then starting the treatment. Identifying and treating early is key! Pests reproduce really quickly – a female spider mite lays up to 20 eggs 
per day – so a few days really can be the difference between a small problem, and a full-blown infestation…

SPIDER MITES

Spider mites love to hide in hard to see places, so make sure you’re checking under the leaves and around the nodes of newly developing leaves, as those little cracks and crevasses could shield mites and their eggs.

These nasty little things really are a curse for indoor growers. They are fairly hard to see with the naked eye, until they start creating webs all over the backs of leaves.

But by the point that you’re noticing their webs, the infestation will be pretty bad already. Don’t let it get to that stage. Use a magnification device
 to spot them.

Spider Mites love it when it’s hot and dry, so one of the key things to prevent an infestation is to watch that humidity level.


It’s important to remember that Spider Mites aren’t technically insects – which means regular insecticides won’t work! Choose a product specifically formulated to stop these tiny arachnids. Guard 'n' Aid Spidermite is a good one!

THRIPS

Thrips are quite different at each stage of their lifecycle, so it’s important to use an all-round product that kills the eggs and larvae as well as the visible adult thrips

These tiny terrors are even harder to spot than Spider Mites. More likely you’ll notice their droppings (which look like black specks), or you’ll just notice the damage they’re doing to your plant’s leaves – leaving them blotchy, malformed, and covered in small silvery/grey spots on the leaf surface.


What’s worse is that thrips are even harder to spot when they are larvae – but this is when they are the most destructive.

But as thrips and their larvae are so small, it can be easy to think you’ve sprayed them all… and be mistaken. You only need to miss a few for that infestation to come back. An adult female thrip can create up to 50 new thrips in their lifetime!
 
When you just can’t seem to get rid of them and they keep coming back, you need to treat your entire growing environment. Fumigation is a fantastic way to make sure that even awkward, difficult to reach places get a good dose of insecticide. A fumer like
Fortefog Fumer is simple to set up and ideal for this purpose, however, if you go down the fumigation route, wait until you are between grows – otherwise you’ll end up with a room of dead plants as well as dead thrips.

APHIDS

Aphids can be incredibly destructive. Fortunately, they are a bit easier to spot – typically these little green or black insects form clusters – but you don’t want to waste any time treating the infestation once you’ve noticed them.

Aphids can be incredibly destructive. Fortunately, they are a bit easier to spot – typically these little green or black insects form clusters – but you don’t want to waste any time treating the infestation once you’ve noticed them. They breed like wildfire and they’ll eat masses of leaves and buds in the process.

To top it off, because they’re so busy enjoying your plant’s sugars, these bugs excrete a sticky, sugary waste product which can attract dark mould.


Don’t let an aphid infestation take a foothold. Use a variety of strategies to get them gone.

Because these insects often form little clusters or clumps on plants, you can fairly easily see where you need to spray an insecticide.
Guard 'n' Aid PestOff Plus works on contact with the bugs, so give them a good spray.
