At Gristwood & Toms, we know managing trees, especially in urban or high-traffic environments, is becoming more complex. With global trade and international travel on the rise, the risk of importing new pests and diseases is increasing. Without early detection and expert care, these threats can spread quickly, damaging valuable trees, disrupting sites, and creating long-term costs.
Undetected pests and diseases compromise long-term tree health and vitality
Tree pests can spread rapidly across a site
Unmanaged trees may become hazardous or non-compliant
Delayed action can lead to full tree removal or site disruption
Our tree pest and disease experts carry out detailed inspections to spot early signs of infestation or infection, assess tree health, and diagnose the cause. We’ll design a tailored management plan with practical steps to contain the issue, restore tree vitality, and protect nearby vegetation.
Where treatment is needed, we use safe, effective solutions including biological controls, and if removal is required, we handle it responsibly and in line with environmental best practice.
Oak Processionary Moth
Effective control relies on precise timing. Our certified teams carry out carefully timed insecticide spraying and safe nest removal using specialist equipment to minimise health risks to people and animals.
Brown Tail Moth
Our tree health specialists remove caterpillar nests and implement targeted control measures to prevent spread and protect nearby trees and public areas.
