With over 25 years of industry experience, Davy Larmour manages the Northern Ireland operation of Complete Weed Control. As a highly-skilled local expert, Davy and his team proudly serve a diverse range of clients, including sports clubs, industrial sites, public utilities, and local authorities.

Complete Weed Control is a leading provider of weed control services in Northern Ireland. Their extensive experience, combined with access to the most efficient technology, machinery, and equipment, ensures that they deliver high-quality services to both residential and commercial clients.

One of their key services is Japanese knotweed removal. Japanese knotweed is a highly invasive plant species that can cause significant damage to properties if left untreated. The team at Complete Weed Control is well-versed in the best methods for eradicating this persistent weed. They employ a combination of chemical treatments, physical removal, and ongoing monitoring to ensure complete eradication.

Complete Weed Control takes pride in delivering efficient and effective weed control solutions that meet the unique needs of each client. They understand the importance of maintaining a weed-free environment, whether it's for aesthetic purposes or to prevent damage to buildings and infrastructure. Their team is fully trained in the safe use of pesticides and adheres to strict health and safety policies.

All work carried out by Complete Weed Control is guaranteed, and they provide a range of documentation, including health and safety policies, COSHH/risk assessments, and method statements. Their team also conforms to BASIS requirements and holds full ISO accreditation.

“Complete Weed Control met expectations on each site with invasive plant infestation coming under control. We would not hesitate to contact them for similar projects in the future” – EnviroCentre, Glasgow "The success of our working relationship with Complete Weed Control (South Wales) has been thanks to a partnership approach and the use of long term contracts. This way of working combined with Complete Weed Control's new technology have played an important part in Cardiff's recent success in both 'Wales in Bloom' and 'Britain in Bloom'"

Mike Clark, Operational Manager (Parks and Bereavement) from Cardiff County Council “I find the contract manager and staff to be polite, knowledgeable and very helpful when extra advice is required. Nothing ever seems to be too much trouble. In my opinion, they provide a value for money, fantastic service which results in weed free streets and housing estates."

Environment Department, London Borough of Barking and Dagenham "I am writing to thank your staff, company and yourself for a First Class service at The University recently. Your staff were all very professional and efficient at what they did, the work was completed with no fuss and a great deal of enthusiasm. Furthermore they kept us informed of any issues or problems that had arisen during the day. All in all I would have no problem recommending your staff and company to other grounds managers with whom I am in contact."
