Understanding Oak Processionary Moth
The Oak Processionary Moth (Thaumetopoea processionea) is a serious pest that primarily targets oak trees. Its caterpillars are covered in long white hairs containing a toxic protein, which poses significant health risks—including skin irritation, respiratory issues, and eye problems. Contact with these hairs is hazardous to both humans and animals. OPM infestations typically begin in late spring and reach their peak in early summer, as the caterpillars form distinctive nests and strip oak trees of their leaves, severely threatening their long-term health.
Where Our Service is Required
Our OPM management service is vital in areas where oak trees are abundant, as these are the primary hosts for this invasive species. Parks, woodlands, and residential areas with mature oak trees are particularly vulnerable. These environments not only provide ideal conditions for OPM to thrive, but also increase the likelihood of human and animal exposure to the pest.
Urban and suburban areas with dense tree cover are especially at risk due to the close proximity of people, pets, and wildlife to infested trees. Our professional service plays a key role in protecting public health, preserving oak tree health, and mitigating the dangers associated with OPM infestations in both public and private spaces.

Managing OPM Infestations
Chigwell Tree Services offers comprehensive solutions to control the spread of Oak Processionary Moth (OPM) and safely remove their nests. Using industry-approved techniques and professional-grade equipment—including pheromone traps and full personal protective equipment (PPE)—we target every stage of the OPM life cycle. Early intervention is essential, as infestations can escalate rapidly. By acting in early summer, when OPM activity peaks, we help safeguard your oak trees and prevent the infestation from worsening.
The OPM Removal Process
Our experienced team follows a thorough and methodical approach to ensure the safe and effective removal of OPM caterpillars and nests:
- Inspection & Assessment – We work closely with local authorities and organisations such as the Forestry Commission to assess the scale of infestation and accurately locate OPM nests.
- Safe Nest Removal – Our technicians use specialist equipment and follow strict safety protocols to remove nests without exposure to the caterpillars’ toxic hairs.
- Ongoing Monitoring – To prevent future outbreaks, we deploy pheromone traps and implement proactive monitoring strategies to detect and reduce the risk of reinfestation in your area.
