Slugs eat leaves, stems and roots of plants, weakening them and often causing them to die.

They leave slimy trails over plants and soil, and are particularly devastating to seedlings and cuttings. Slugs leave their own individual scent trails so they can find their way home. There are other creatures (like caterpillars) who make big holes in leaves, but if you see the tell-tale slime, then slugs are the culprit!

Slugs come in many shapes and sizes and are commonplace around the garden, particularly in damp conditions.

Infestations are less serious in dry weather but tend to become a problem during prolonged rainy weather. An individual grey field slug has the potential to produce 90,000 grandchildren and has approximately 27,000 teeth!

They live underground during the day, emerging at night to feed. One cubic metre of garden will on average contain up to 200 slugs.

We supply packs of microscopic beneficial nematodes, Phasmarhabditis hermaphrodita, which are watered into pots or open ground with a watering can or hose. They enter the slug through a hole in its back while it is underground and poison it so that it will die within a few days underground, out of sight.

Traps are a great way to find out what pests are present on your plants and can trap a good quantity of flying and crawling pests.

Sold in packs of 5.

Sticky traps are a great way of monitoring and reducing pest numbers. 

Yellow catch aphids, whitefly, leafminers, fungus gnats and more.   The yellow trap are eco friendly card traps.

Blue traps are great for thrips.

Red traps for monitoring and controlling leafhoppers.

Vine Weevil nematodes are watered into pots or open ground with a watering can or hose, killing the vine weevil grubs.

Use as soon as the soil temperature reaches 5°C.  The parasitic nematodes enter the grub, poisoning it and then feeding off it to increase their numbers.

Sold in 2 sizes.

Biological controls are not always kept in stock, they are ordered in fresh.  This can sometimes lead to a time lag between when you place the order and when it is despatched.  Order by 10am Monday for same week despatch.

The most effective treatment for whitefly is the parasite "Encarsia". It is supplied on small cards which can be hung up around your plants.  You can read the instructions for this product HERE.

The smallest packs (5 & 10 cards) are only available March to mid September.  Biological controls are not always kept in stock, they are ordered in fresh.  This can sometimes lead to a time lag between when you place the order and when it is despatched.  Order by 10am Monday for same week despatch.

Glasshouse whitefly are small white flying insects which lay eggs on the undersides of leaves. Whiteflies suck sap from their host plant and drop sticky secretions onto leaves below. Left uncontrolled they will overwhelm the plant, weakening it and flying around in huge numbers. Undersides of leaves become populated with Whiteflies adults and white eggs (scales).

Whitefly are fairly inactive in cool temperatures over Winter, but multiply very quickly in warm Spring and Summer weather. They fly about at the slightest disturbance, like tiny moths, and may even create ghostly white clouds in the air.

Instructions for use

Encarsia works best with temperatures above 21°C but prefer cool glasshouse conditions below 25°C with 12hr+ daylight hours. Generally, this means introducing Encarsia from mid March to August, although it can be earlier or later with extra heat and light.

Hang cards on lower branches so that they may be in a slightly shady position.

5 cards should give good control for an average conservatory or small greenhouse. If you have a longstanding battle with whitefly follow up the initial treatment with a second introduction one weeks later.  If you have a low lever of whitefly or are using Encarsia as a preventative method then application can be every 2 weeks.

Identifying Whitefly

Remember whiteflies are nearly always moving. If you see white threads static on tops of the leaves, they are not whitefly but something else - very likely to be shed aphid skins dropped down from developing Aphid under leaves above. Or they could be thrips larvae. They are not "whitefly" unless body and wings are a ghostly white.

The glasshouse whitefly (Trialeurodes vaporariorum)is the most common. You can recognise them by their heart-shape profile when looked from above. Tobacco whitefly (Bemisia tabaci) have parallel wings which are longer, and when folded you can still see a strip of their back between the wings. There are up to 50 different species of whitefly in Europe, but from a gardeners point of view they are all plant pests. 

Although Encarsia is very effective for the common glasshouse whitefly, it doesn't work so well for tobacco whitefly. It's therefore worth trying to identify what whitefly you have before treating. If you need any help identifying the whitefly you have then please don't hesitate to contact us.
