Pest guides for the plants grown by Snip & Sprout

Professional identification and management guidance for the pests most relevant to the aroids, Hoyas, succulents, foliage plants and carnivorous plants in this collection.

Identify before treating

Inspect new growth, leaf undersides, petioles, stems, leaf joints and the potting medium with a bright light. Damage alone is not enough to identify a pest.

Use UK-authorised controls only

Where a pesticide is needed, use a product authorised for home-garden use in the UK and follow its label. Never increase the concentration or improvise pesticide mixtures.

Expect follow-up checks

Eggs, protected stages or insects hidden in crevices can survive an initial treatment. Keep the plant isolated and repeat inspections at the stated interval.

Pests covered

The realistic UK indoor risks for this collection

Limited to pests relevant to the plants Snip & Sprout grows.

Indoor scope: Every pest below can affect houseplants or plants grown under cover. Thrips, spider mites, mealybugs, scale and fungus gnats are the most routine indoor checks. Aphids and whitefly are less frequent indoors, but can arrive on new plants, flowers or plants moved between indoor and outdoor spaces. Outdoor-only pests are not included.

Glasshouse thrips

Most relevant to: Alocasia, Monstera, Philodendron, Epipremnum, Syngonium, Scindapsus, Tradescantia and Ficus.

Look for
Silvery or bronze scarring, distorted new leaves, black faecal specks and narrow cream, yellow or dark insects.
Check
Unfurling leaves, petiole grooves, leaf undersides and growing points.
Manage
Isolate, remove only severely damaged material, wash sturdy foliage where practical and use an appropriate UK-authorised control or professional biological-control programme. Follow-up is essential because eggs and pupae may escape the first treatment.

Glasshouse red spider mite

Most relevant to: Alocasia, Ficus, Schefflera, Maranta, Fittonia and Tradescantia.

Look for
Fine pale stippling, dull or bronzed foliage, tiny moving mites and fine webbing when numbers are high.
Check
Leaf undersides and petiole junctions. Tap foliage over white paper to make mites easier to see.
Manage
Isolate, wash suitable foliage, clean the growing area and use a control specifically labelled for mites or a suitable biological control. Warm, dry conditions favour rapid increase.

Glasshouse mealybug

Most relevant to: Hoyas, succulents, Ficus, Schefflera and aroids with tight leaf joints.

Look for
White waxy insects or cottony deposits, sticky honeydew, yellowing and sooty mould.
Check
Nodes, petiole bases, leaf axils, pot rims and support ties. Inspect roots if decline has no obvious above-ground cause.
Manage
Isolate, remove visible insects where practical and use a labelled treatment or appropriate biological control. Repeat inspections because juveniles are easily missed.

Scale insects

Most relevant to: Ficus, Schefflera, Hoyas and thick-stemmed succulents.

Look for
Fixed brown, tan or pale shell-like bumps, honeydew, sooty mould and weak growth.
Check
Stems, leaf undersides, veins and sheltered joints.
Manage
Remove manageable colonies without damaging the plant and use a labelled control if needed. Newly hatched crawlers are less protected than adults.

Fungus gnats (sciarid flies)

Most relevant to: Moist propagation media, Fittonia, Maranta and young aroids.

Look for
Small dark flies around damp compost and translucent larvae with black heads in the root zone.
Understand
Adults are mainly a nuisance. Large larval populations can damage seedlings and very young roots.
Manage
Correct avoidably wet conditions where the plant allows, remove decaying debris, monitor adults with yellow traps and use a recognised larval biological control such as Steinernema feltiae.

Aphids

Most relevant to: Tender new growth, flower stems, Nepenthes, sundews and soft foliage plants.

Look for
Clusters of soft-bodied insects, shed white skins, sticky honeydew and curled young growth.
Check
Growing tips, buds, flower stems and the youngest leaves.
Manage
Isolate, wash colonies off where the plant tolerates it and use a labelled treatment or suitable biological control.

Glasshouse whitefly

Most relevant to: Soft-leaved foliage plants grown warm indoors or under cover.

Look for
Small white adults flying when foliage is disturbed, honeydew and flat immature stages beneath leaves.
Check
The underside of newer but fully expanded leaves.
Manage
Isolate, remove heavily infested leaves where sensible, monitor adults with yellow traps and use a labelled treatment or professional biological control.

Root mealybugs

Most relevant to: Succulents, Hoyas and container-grown foliage plants showing unexplained decline.

Look for
White waxy deposits around roots, pot edges or drainage holes and weak growth.
Check
The root ball and inside of the pot. Keep suspects away from shared watering trays.
Manage
Isolate immediately, discard contaminated medium safely, clean pots and tools and follow current professional guidance for treatment or disposal.
Treatment workflow

A repeatable response

  1. 1

    Isolate and inspect nearby plants

    Move the affected plant away and inspect plants that shared shelving, tools, trays or close foliage contact.

  2. 2

    Confirm the pest

    Use the insect, shed skins, webbing, honeydew or other direct evidence. Do not treat solely from yellowing or distortion.

  3. 3

    Reduce the population safely

    Remove badly damaged material only where useful, wash robust foliage where appropriate and clean shelves, tools and reusable pots.

  4. 4

    Choose one compatible control programme

    Use an authorised home-garden product or professional biological-control programme and check compatibility before combining approaches.

  5. 5

    Reinspect before returning the plant

    Keep it isolated until repeated close inspections find no live pests or fresh damage.
