Pests (such as rodents, cockroaches, ants and birds) pose a direct threat to the packaging and quality of medicines. An effective, ongoing pest control programme is therefore a basic GDP requirement for storage facilities. The programme should be based on a risk assessment of the warehouse environment. Specific requirements include: 1. Keep the area around the warehouse clean and remove potential breeding sites; 2. Ensure the warehouse structure is in good condition and seal all possible pest entry points (such as gaps around doors and openings for pipes); 3. Strategically place monitoring and control devices, such as rodent traps and insect glue boards, inside and outside the warehouse, and prepare a placement plan; 4. Inspect these devices regularly and record inspection findings and any pests caught; 5. Manage waste strictly and remove it promptly. As pesticides may themselves contaminate medicines, open toxic baits and spray pesticides should be avoided in medicine storage areas.

📘 Regulatory basis

Chapter 3, “Premises and Equipment”, of the Good Distribution Practice (GDP) for Medicinal Products requires storage areas to be kept clean, with appropriate procedures for cleaning up any spillages, and an effective pest control programme to be implemented. Pest control substances must not themselves pose a contamination risk to medicines.

📗 Drew Tang's recommendations

We strongly recommend outsourcing pest control to a professional and reputable third-party company. Such companies have the expertise, equipment and compliant pesticides to provide systematic services and complete documentation (such as service reports, site plans showing treatment points and pesticide safety data sheets). This is more efficient, safer and easier to demonstrate as compliant during regulatory inspections than handling it yourself. You should sign a contract with the service provider and review its service reports regularly.

📕 Risk notice

Signs of pest activity in a warehouse, such as droppings or gnaw marks, indicate a serious failure to meet hygiene standards. If pests damage the integrity of medicine packaging, the entire batch may be regarded as contaminated and have to be destroyed. Improper use of pesticides by staff can have consequences worse than the pests themselves if the medicines become contaminated.
