What is the difference between PA1 and PA6 for grey squirrel control?

PA1 is the foundation module covering general pesticide safety, storage, transport, and legal responsibilities. PA6 is a specific module for vertebrate pest control, focusing on the safe use of pesticides for animals like grey squirrels. You must pass PA1 before or alongside PA6 to obtain the full qualification.

Can I use warfarin to control grey squirrels?

No, warfarin is no longer approved for outdoor use against grey squirrels in the UK. Only certain second-generation anticoagulant rodenticides (e.g., difenacoum, bromadiolone) are authorised. Always check the current list of approved products on the Health and Safety Executive (HSE) website.

How do I prevent non-target animals from accessing bait?

Use purpose-designed bait stations that are secured to the ground or trees. Place bait inside a tunnel or box with an entrance sized to exclude larger animals (e.g., badgers, dogs) and use baffles or grilles to deter birds. Regularly check stations and remove any spilled bait.

What should I do with dead grey squirrels?

Carcasses must be disposed of safely to prevent secondary poisoning. Wear gloves, double-bag the carcass, and dispose of it in a licensed incinerator or landfill. Alternatively, deep burial (at least 60 cm) away from water sources is acceptable. Record disposal details in your records.

Is it legal to shoot grey squirrels instead of using pesticides?

Yes, shooting is a legal method of control, but it requires a firearms certificate if using a rifle. Air rifles (up to 12 ft-lb) can be used without a certificate on land where you have permission. However, the NPTC award focuses on pesticide use; shooting is covered under separate qualifications.

How often should I check bait stations?

Bait stations should be checked at least every 7 days to monitor bait uptake, replenish bait, and remove any dead squirrels. More frequent checks may be needed in high-activity areas or during wet weather to ensure bait remains dry and palatable.

Practices of using Rodenticides for Vertebrate Pest Control, Grey Squirrels

CITY AND GUILDS OF LONDON INSTITUTE

vocational

This element focuses on the safe and effective application of rodenticides for controlling grey squirrels in line with UK legislation and best practice. Candidates must demonstrate the ability to integrate site-specific risk assessments, environmental considerations, and correct product handling to minimise non-target exposure and ensure public safety. The learned skills are directly applicable to professional roles in pest management, forestry, and conservation.

City & Guilds NPTC Level 2 Award In the Safe Use of Pesticides for Vertebrate Pest Control for Grey Squirrels

Topic Overview

This qualification covers the safe and effective use of pesticides for controlling grey squirrels, a species classified as invasive and a significant pest in UK woodlands and urban areas. You will learn to identify grey squirrels, understand their biology and behaviour, and apply appropriate control methods using approved pesticides, primarily anticoagulant rodenticides. The course emphasises legal compliance, environmental safety, and best practice to minimise risks to non-target wildlife, pets, and humans.

Grey squirrels cause damage to trees by bark stripping, which can lead to economic losses in forestry and harm to native biodiversity. They also outcompete red squirrels and damage property. Effective control is essential for conservation and land management. This award ensures you are competent to handle and apply pesticides safely, following UK legislation such as the Food and Environment Protection Act (FEPA) and the Control of Pesticides Regulations (COPR).

The qualification is part of the wider NPTC suite of pesticide awards, building on foundational knowledge of pesticide safety. It is often taken alongside the Level 2 Award in the Safe Use of Pesticides (PA1) and a specific module for vertebrate control (PA6). Mastery of this topic enables you to contribute to integrated pest management (IPM) strategies, balancing control with humane and environmental considerations.

Key Concepts

Core ideas you must understand for this topic

→Identification and biology of grey squirrels (Sciurus carolinensis) – distinguishing from red squirrels, understanding breeding cycles, feeding behaviour, and habitat preferences.
→Legal framework – Wildlife and Countryside Act 1981 (scheduling grey squirrels as a pest), Pesticides Regulations, and the requirement for a specific pesticide application certificate (PA6).
→Anticoagulant rodenticides – mode of action (vitamin K antagonism), active ingredients (e.g., difenacoum, bromadiolone), and the risk of secondary poisoning to predators and scavengers.
→Baiting strategies – placement in bait boxes or hoppers to exclude non-target species, use of appropriate bait types (e.g., whole maize, peanuts), and monitoring bait uptake.
→Environmental and safety precautions – personal protective equipment (PPE), disposal of carcasses, record keeping, and mitigation measures to protect red squirrels and other wildlife.

Learning Objectives

What you need to know and understand

Be able to comply with the legislative and safety regulations relating to rodenticide use for the control of Grey Squirrels, Be able to assess the environmental factors relating to application, Know the characteristics of Grey Squirrels and their impact on the environment, Know the methods of preventative management and control for Grey Squirrels, Be able to complete a site survey prior to carrying out Grey Squirrel control, Be able to apply rodenticide products safely, Know how to carry out post operational procedures

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for accurately referencing the Control of Pesticides Regulations and relevant approval conditions for the rodenticide product being used.
Look for evidence of a thorough environmental risk assessment, specifically noting proximity to watercourses, non-target species, and public access areas.
Assess the candidate's choice of baiting points based on a site survey that identifies grey squirrel activity, entry routes, and secure, tamper-resistant placement.
Check that personal protective equipment is correctly selected, worn, and maintained throughout the application process as per product label instructions.
Confirm that post-operational records include bait station location mapping, quantities used, and any carcass search and disposal details.

Assessment Guidance

Guidance for achieving higher grades

💡Always link your site survey findings to your application strategy; explain how observed squirrel activity and environmental constraints dictated your baiting points.
💡Prepare a mock operational record sheet and rehearse completing it with all legally required information, as this is often assessed in practical observations.
💡Know the legal status of grey squirrels – they are not protected under the Wildlife and Countryside Act 1981, but you must still follow animal welfare laws (e.g., avoid unnecessary suffering). Examiners look for understanding of the balance between control and humane practice.
💡Be precise about bait station design and placement. Describe how to secure stations to prevent access by non-target species, and explain why location (e.g., near runs or dreys) is critical for efficacy.
💡In written assessments, always link safety measures to specific risks. For example, when discussing PPE, state that gloves prevent skin absorption of anticoagulants, and that respirators may be needed when handling dusty formulations.

Common Mistakes

Common errors to avoid in your coursework

Failing to secure bait stations adequately, leading to access by non-target animals or the public.
Misidentifying grey squirrel signs, confusing them with red squirrel or bird activity, which can lead to ineffective or illegal control measures.
Neglecting to check and record daily bait take during the treatment period, resulting in prolonged exposure and increased risk.
Overlooking the requirement to search for and safely dispose of poisoned carcasses to prevent secondary poisoning of wildlife.
Misconception: Grey squirrels can be controlled using any rodenticide. Correction: Only specific anticoagulant rodenticides approved for outdoor use against grey squirrels are permitted; indoor rodenticides must not be used outdoors.
Misconception: Bait can be placed openly on the ground. Correction: Bait must be placed in secure, tamper-resistant bait stations to prevent access by non-target animals, children, and pets.
Misconception: Once squirrels are controlled, the problem is solved permanently. Correction: Grey squirrels are highly mobile and can reinvade from surrounding areas; ongoing monitoring and periodic control are often necessary.
