Pest Control

Our pest control range

At Plant & Flower, your Belgian grow shop since 2011, we stock exclusively biological and mechanical treatments against indoor grow pests. Thrips, aphids, fungus gnats (sciarids), whitefly and spider mites are the most common pests. Each species attacks differently — thrips pierce leaf cells, aphids suck sap, fungus gnats chew roots. Effective pest control therefore combines prevention, early detection and targeted intervention, without chemical residues that compromise your harvest or disrupt the ecosystem inside your grow tent.

The three pillars of effective pest management

No single product covers every scenario. An integrated approach relies on early detection (yellow sticky traps), preventive protection (foliar barrier and plant strengthening) and curative contact treatment (insecticidal soap). These three layers complement one another without interference.

Foliar protection and internal strengthening

Biobizz Leaf Coat 0.5 L deposits a thin natural latex film on leaves, creating a physical barrier that piercing-sucking insects cannot penetrate. The coating is fully organic, does not interfere with photosynthesis or transpiration, and doubles as a moisture regulator in dry environments. Apply it as a foliar spray during the vegetative phase only — avoid use once flowering begins to prevent film residue on buds.

BAC Plant Vitality Plus 250 ml works differently: it boosts the plant's internal defences by altering sap composition, making leaf tissue far less palatable to sucking insects. Dosage: 2 ml per litre of water, as foliar spray or root drench. The 500 ml bottle offers better value for growers running multiple plants. Leaf Coat and Plant Vitality Plus pair perfectly: Leaf Coat in the morning on foliage, Plant Vitality Plus via the watering can.

Curative treatment: Neudorff black soap

Neudorff black soap is a time-tested contact insecticide that dissolves the protective waxy layer of soft-bodied insects — aphids, scale, whitefly and spider mites die on contact without leaving toxic residues. This makes it one of the few treatments safe to use right up to the final weeks before harvest. Target the undersides of leaves (where most pests concentrate), preferably in the evening or early morning when grow lights are off to avoid foliar burn. Repeat every 3 to 5 days until the infestation is completely gone — black soap has no residual effect, so each application only kills what it contacts at the moment of spraying.

Layered approach and healthy environment

The most effective pest management stacks multiple strategies that reinforce each other:

• Yellow sticky traps for early detection and mass trapping of flying adults (1 trap per m² for monitoring, 2 per m² during active infestation)
• Leaf Coat as a preventive physical barrier during vegetative growth — effective against thrips and spider mites in early stages
• Plant Vitality Plus for ongoing internal resistance building
• Black soap as a targeted curative spray when visible infestation occurs
• Environment: proper ventilation, clean grow space free of dead leaves and growing medium debris

Pay extra attention during vulnerable periods: the transition to flowering and the first weeks after transplanting fresh clones carry the highest risk of infestation. For fungus gnats specifically, allow the top layer of substrate to dry thoroughly between waterings — the larvae cannot survive in dry conditions, and this simple measure reduces populations significantly without any additional products. A top layer of perlite on the substrate speeds drying and makes it harder for adult gnats to lay eggs.
