Unfortunately we haven't put the greenhouse up yet due to garden building project being delayed however the service provided by greenhouse stores is highly recommended

Wind blew some glass out. We changed the clips for bar capping, we should have had this when we ordered the greenhouse, just didn't realise.
Great company really satisfied but would advise the capping when you order your greenhouse.

I was upset about the 7 week wait. But the greenhouse was worth the wait. I didn’t have a problem with the instructions we built if fine. Great quality, even had extra glass included. Don’t look anywhere else just get this one Vitavia one. I got the black love it. Vitavia deliver the greenhouse themselves, nice Guy.

It will be useful when finished but it's not a straightforward build. Can't fathom why it's so complicated.

Verified Customer

every thing went smoothly, from upgrading my order to delivery

Verified Customer

The product came very well packed and the driver put it where requested on my drive. I was called a week before delivery by the office to confirm the day. Almost everything needed to construct the greenhouse was included except spanners. Wall fixings, mastic and gun were. The manual was very good but does need to be read before starting and may be a bit difficult for a non practical person to get their head around. I Would definitely recommend Greenhouse Stores and the Elite Easygrow lean-to.

Excellent varied stock. Prices & inclusive items were very favourable. Delivery & erected Swallow Jay potting shed was swift , professional, polite & efficient. I am extremely satisfied with my experience with Greenhouse Stores

Verified Customer

The instructions were very good and building the greenhouse was like a giant mechano set. The one thing that threw me was the website and instructions showed the glazing for the walls in two pieces. What was delivered were single sections and it took me a while to find the revised instructions.

Verified Customer

I haven't managed to erect my greenhouse yet, but so looking forward to having it.

Choose treatment by pest and life stage

Nematodes are microscopic living organisms. Choose a treatment for the pest you have identified, then compare its stated coverage with the affected area. We recommend checking the pest's life stage before choosing your product. Nemasys vine weevil larval nematodes target larvae. The NemaTop adult vine weevil trap is a separate life-stage choice.

Keep those choices separate when comparing products. A larval treatment and an adult trap target different stages of vine weevil. For help identifying a treatment, read our complete greenhouse pest control guide. Measure affected soil, compost or lawn before choosing an area-based treatment. For ant treatments, compare the stated nest coverage instead.

Compare pest treatments and coverage

Coverage belongs to the individual treatment and format. Do not use one product's area allowance for another pest. The separate fungus gnat pod format also needs its own product instructions.

Nemaslug slug nematodes	40 or 100 m²
Nemasys vine weevil larval nematodes	12 or 100 m²
Nemasys chafer treatments	100 or 500 m²
Nemasys leatherjacket treatments	100 or 500 m²
Ant treatments	Up to 16 or 50 nests

Snail treatment	40 m²
Thrips treatment	Two 30 m² sachets

Application and storage

Many treatments mix with water for affected soil or compost, through a watering can or suitable sprayer. Traps and pods have different application methods. Follow pack-specific temperature, storage, expiry and moisture requirements. There is no universal temperature threshold or application season across this range.

Check the application method before choosing equipment from our greenhouse accessories. Confirm that your watering can or sprayer is suitable for the selected treatment.

Frequently asked questions

Which treatment should I choose for slugs?

Nemaslug slug nematodes cover 40 or 100 square metres. Measure the affected area and choose the corresponding coverage.

How do I compare fungus gnat formats?

Fungus gnat nematodes have a 12-square-metre treatment and a separate 200-pod format. Do not assume the pod format has the same area coverage.

How are nematode treatments applied?

Many nematode treatments mix with water for affected soil or compost. Use a watering can or suitable sprayer where instructed. Traps and pods differ.

How should I store my treatment?

Follow the storage and expiry instructions on your selected pack. Temperature and moisture requirements also depend on the treatment. Check these instructions before application.
