Faced with a pest in the garden, many clients first try over-the-counter products, but there are cases where the problem requires a professional plant-protection treatment, with products and application beyond what a private individual can buy and apply on their own.

When a home treatment is not enough

Widespread pests on large trees, infestations detected late that have already seriously weakened the plant, or regulated quarantine pests (such as certain listed boring insects) require professional-use products and, in some cases, notification to the competent agricultural authorities.

Pesticide applicator licence

To apply certain professional-use plant-protection products, the applicator must hold the relevant licence required by regulations, something that sets a gardener qualified for this type of treatment apart from one who only does standard maintenance. The client should know that this service requires specific qualification.

Diagnosis before treating

Applying a generic product without properly identifying the specific pest may not solve the problem or may even damage the plant through an unsuitable treatment. A correct diagnosis (identifying the pest and its cycle) should be the first step before quoting any plant-protection treatment.
