Save your houseplants and seedlings from Sciarid fly/Fungus gnats and larvae damage with our parasitic nematodes. 

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.

The adult fungus gnats/sciarid flies live on and around the compost surface of pots, more commonly indoors rather than outside. The flies themselves are an unsightly nuisance but most of the damage is caused actually by their young. The small white larvae live in the compost and feed on the tender roots of plants and cuttings. They will also come to the surface to feed. 

Nematodes are more effective if the sciarid population is high. The nematodes are watered on, and attack the sciarid larvae underground. Parasitic nematodes seek out suitable hosts by swimming in the thin film of water on soil particles, locating hosts by detecting carbon dioxide and other waste products. Once they find a host, they enter the body cavity through the breathing or feeding systems, and release bacteria (Xenorhabdus). The bacteria kills the host within hours, and the nematodes grow and reproduce within the 'broth', which they produce. The next generation of infective juveniles leaves the dead host, and moves in search of fresh hosts.

You can read the instructions for the nematodes HERE.

Combine with yellow sticky traps for better control.  A second treatment may be required depending on the level of infestation and the life cycle stage of the pest.

We offer an effective nematode treatment to get rid of ants in your garden.

These nematodes deter ants, driving them out of their nests and making them go elsewhere. Do not purchase until soil temperatures are above 10°C.  The species of nematode contained in the pack is steinernema feltiae.

Adults actively hunt for aphid colonies - Once an adult female (around 2mm long) finds a colony she will lay her eggs next to it - The eggs hatch into highly visible orange larvae which feed on the colonies of all types of aphids. Up to 60 different species of aphid.  Larvae inject a poison into the aphid to paralyse it and dissolve the body contents.

The larvae take 7-16 days to mature before pupating in soil or compost and adults emerge after 10-14 days.  You can read the instructions for this product HERE.

Orders placed by 10am Monday will be despatched later in the week.  The smaller size packs, 250 cocoons are only available March - September.

This is our most effective control for aphids in enclosed spaces and greenhouses and is favoured by commercial growers.

Aphidius are the most popular, and least expensive way of controlling common aphids, which is why they are the first choice for the commercial grower. Aphidius colemani tend to tackle the smaller aphids such as Myzus persicae and Aphis gossypii - for larger aphids there are Aphidius ervi. 

Sold in tubes of 500.  Orders placed by 10am Monday will be despatched later in the week.  You can read the instructions for this product HERE.

The box tree moth has now become an important pest on box (Buxus spp.), especially across the South of England. The larvae (caterpillars) feed on the foliage and within days can cause severe levels of defoliation and dieback.  The Caterpillar can be controlled with nematodes.  You can read the instructions for the nematodes HERE.

Spotting the pest

You may notice webbing or the caterpillars, you will also see their yellow eggs on the underside of leaves.  The adult moth is brown.

Control

Remove as many caterpillars as feasible by hand along with leave that have extensive webbing.

We have been recommending nematodes for a couple of years, a recent study by the RHS has confirmed that they considerably reduce larvae numbers, therefore reducing pest numbers by affecting this life stage.

There are 2 generations of Box tree moth per year so nematodes treatments in spring and mid summer are a good idea, the air temperature should be 12°C or above.

Stephanie Bird, RHS Entomologist said ‘Nematodes can be a useful addition to the gardener’s armoury for control of box moth caterpillar’

Ideally you do 3 applications 2 weeks apart at each treatment time, the packs will last in your fridge for 2-3 weeks so only buy the first 2 doses.

The RHS would like to know if you have made a sighting of this pest, please fill out the survey here

Citrus trees work hard to produce flowers and then grow the fruit, as well as keeping the foliage green and growing. If short of essential minerals they may abort their fruits or concentrate on growing the fruits at the expense of the leaves. To help them stay healthy, they need regular feeding with a finely-tuned fertiliser which will give them the nutrients they need to perform all these tasks. Light green or yellow leaves on the new growth is a sign of lack of nutrients.

Stop pests attacking your fruit and vegetables with nematodes.

These multitarget parasitic nematodes target all a range of pests including; Codling Moth, Shore Fly, Sciarid Fly, Caterpillars, Root Fly, Gooseberry Sawfly, asparagus beetle larvae, wireworm, viburnum beetle larvae and more.

Save your houseplants and seedlings from Sciarid fly/Fungus gnats and larvae damage with our best selling solution. (Steinernema Feltiae/Carpocapsae mix).

The adult sciarid flies live on and around the compost surface of pots, more commonly indoors rather than outside. The flies themselves are an unsightly nuisance but most of the damage is caused actually by their young. The small white larvae live in the compost and feed on the tender roots of plants and cuttings. They will also come to the surface to feed. 

You need to control both the adults and the larvae or you will not break the cycle.

For the adults use the new eco yellow sticky traps, you get 5 (12cm x 5cm) traps.

For the larvae nematodes are watered onto deal with the larvae underground. Parasitic nematodes seek out suitable hosts by swimming in the thin film of water on soil particles, locating hosts by detecting carbon dioxide and other waste products.

Once they find a host, they enter the body cavity through the breathing or feeding systems, and release bacteria (Xenorhabdus). The bacteria kills the host within hours, and the nematodes grow and reproduce within the 'broth', which they produce. The next generation of infective juveniles leaves the dead host, and moves in search of fresh hosts.  You can read the nematode instructions HERE.

A second treatment of nematodes may be required depending on the level of infestation and the life cycle stage of the pest.

Highly refined soap made from natural oils which acts as a contact insecticide with no residual effects once it has dried.

Sold in 250ml bottles.  The soap has a gel like consistency, it is more liquid at warm temperatures.  This is completely normal.  Spray bottle not included.

Hypoaspis (also known as  Stratiolaelaps scimitus) are mobile predatory mites that feed on sciarid fly larvae and other 'soil' pests including springtails, thrips pupae, root weevils, root aphids and root mealybug. They will also control overwintering spider mites. 

The mites are small, barely visible to the naked eye, and have a light brown to tan colour. They are beneficial because they feed on a variety of harmful pests, including fungus gnats, thrips larvae, root aphids, and other small insects and mites that reside in the soil. These predatory mites are particularly effective in controlling pests in the early stages of their life cycle. 

When introduced into the soil or growing media of plants, the mites actively search for prey, consuming the pest larvae and eggs, thus helping to reduce their populations and prevent potential damage to crops. They are considered a safe and environmentally friendly alternative to chemical pesticides, making them a valuable tool in integrated pest management strategies.

Finally, you can net off your fruits and veg in an eco-friendly way that doesn't generate harmful plastic waste.

Plastic-free, biodegradable insect netting. Made from plants, not petroleum.

Looks like plastic, feels like plastic, but is not plastic.

Protect your fruit and vegetables from common garden pests such as flies, butterflies and birds. The fine mesh ensures protection against even the smaller pests whilst allowing a high amount of light penetration to ensure good growth.

Shipped in recyclable packaging. InsectoNet comes as a single piece of fabric 2.1 by 5.0 metres in size that can easily be cut to size. The high quality fabric means it won't fray on the edges when cut. It lasts at least 3 years.

Use from planting until harvest, approximately April - September.

Do not use during flowering period for plants which require pollination.

Flies, butterflies and moths are often attracted to fruit and vegetable plants to lay eggs which hatch into devastating pests. If adults are kept away from plants, they cannot lay eggs. Using a fine net prevents egg laying and therefore the need to control feeding pests.

The 0.85mm fine mesh provides excellent protection against many pests including;

Cabbage Root Fly

Carrot Root Fly

Onion Fly

Cabbage White Butterfly

Pea Moth

Leek Moth

Cutworm

Thrips

Whitefly

Leaf Miners

Many common aphid species

Some variants have been taken off sale while supply catches up with demand, they will be back within a week.  A great alternative to ladybird larvae are aphid midge, or for larger areas lacewing larvae, both of these can be found here.

Both Ladybird adults and their Ladybird larvae are voracious eaters and can make a real difference to aphid (greenfly and blackfly) infestations both under glass and outside.

The ladybirds we supply are Adalia Bipunctata - the red two-spotted ladybird. They are one of many native species in the UK.  Ladybirds are one of the most popular controls for aphids but they do not prey on other insects so will not help with pests such as thrips and spider mite.  You can read instructions on how to release ladybirds for aphid control HERE.

The larvae are a more reliable predator as they cannot fly away.

If you have a large area to treat or have aphids in multiple areas of your home or garden then Lacewing larvae may be more suitable.

Some pack sizes are only available March to September.

Orders placed by 10am Monday will be despatched later in the week.
