The 1 litre bottles of this product are short dated with a best before date of 21/08/26, which is why they have been reduced from £20.99 to just £14.99 while stocks last. As Defence 7 is a concentrated disinfectant designed to kill bacteria, viruses, and fungi, it is generally considered safe and effective to use beyond its best before date when stored correctly in its original sealed container, away from extreme temperatures and direct sunlight. Best before dates on disinfectants indicate the period during which the manufacturer guarantees peak potency and performance, rather than when the product suddenly becomes unusable. Over time there may be a gradual reduction in strength, but the disinfectant remains suitable for routine cleaning and hygiene use well beyond this date provided the liquid appears normal and has been stored properly. A fantastic opportunity to stock up on a high-quality avian disinfectant at a heavily reduced price.

Defence 7 can form part of a regular hygiene and biosecurity programme for:

• Chicken coops
• Poultry houses
• Pigeon lofts
• Aviaries
• Bird housing
• Breeding pens
• Quarantine areas
• Nesting areas
• Smallholdings
• Poultry equipment
• Bird transport equipment
• Washable feeders
• Washable drinkers
• Floors and walls
• Wood and timber surfaces

• Plastic and metal equipment

Why Bird Biosecurity Matters

Birds can be exposed to infectious organisms through contaminated housing, equipment, footwear, transport crates, wild birds, new stock and other environmental sources.

Regular cleaning followed by appropriate disinfection helps reduce the environmental pathogen load and break routes of disease transmission.

This is particularly important in:

• Multi-bird households
• Breeding establishments
• Poultry flocks
• Pigeon lofts
• Areas visited by wild birds
• Quarantine areas
• Housing used by newly acquired birds
• Environments following illness

Good biosecurity involves more than simply making an area look clean.

Clean first. Disinfect second.

How To Use Defence 7

1. Remove Birds

Remove birds from the area before cleaning and disinfecting.

2. Remove Contamination

Remove:

• Bedding
• Droppings
• Feathers
• Feed debris
• Mud
• Other loose organic material

For heavily contaminated areas, thoroughly clean the surface before applying disinfectant.

3. Prepare Defence 7

For routine poultry disinfection and its DEFRA-approved Poultry Diseases dilution:

Dilute Defence 7 at 1:100.

That's:

10ml Defence 7 per 1 litre of water.

Defence 7 dilutes readily with cold water.

4. Apply Thoroughly

Apply the prepared solution to cleaned surfaces, ensuring good coverage.

It can be used on appropriate:

• Floors
• Walls
• Housing
• Equipment
• Nest boxes
• Feed equipment
• Drinkers
• Transport equipment
• Other washable surfaces

5. Use the Correct Application Rate

For appropriate surface coverage:

Non-porous surfaces such as plastic and metal: Apply approximately 100ml of diluted solution per m².

Porous surfaces such as wood and concrete: Apply approximately 300ml of diluted solution per m².

Porous surfaces require more solution to achieve thorough penetration.

6. Allow to Dry

Allow treated poultry housing to dry before replacing clean bedding and allowing birds back into the area.

Feeding and drinking equipment should be appropriately rinsed before being returned to use where required by the product instructions.

7 Days' Residual Activity

Defence 7 doesn't simply provide disinfection at the point of application.

The manufacturer states that it provides 7 days' residual activity, making it particularly useful as part of a structured poultry and bird-housing biosecurity programme.

Environmental contamination can be reintroduced after cleaning, so good management, appropriate cleaning frequency and ongoing biosecurity remain important.

Effective Even in Soiled Conditions

Animal environments are challenging places to disinfect.

Organic material can reduce the effectiveness of many disinfectants, which is one reason physical cleaning before disinfection remains so important.

Defence 7 is specifically formulated to remain active even in very soiled conditions, providing additional reassurance in demanding poultry and animal environments.

Porous vs Non-Porous Surfaces

Different surfaces require different amounts of working solution.

Non-Porous Surfaces

Examples include:

• Plastic
• Metal
• Smooth washable equipment

Recommended application:

100ml diluted solution per m²

Porous Surfaces

Examples include:

• Wood
• Timber
• Concrete

Recommended application:

300ml diluted solution per m²

The higher application rate helps provide adequate penetration into porous materials.

Important Biosecurity Information ⚠️

Disinfection is only one part of disease prevention.

For the best results:

Remove contamination → Thoroughly clean → Apply Defence 7 at the correct dilution → Allow to dry → Add clean bedding → Return birds

Never rely on disinfectant as a substitute for appropriate veterinary advice, quarantine, vaccination, disease surveillance or statutory disease-control measures.

If Avian Influenza or another notifiable disease is suspected, follow the applicable official veterinary and government guidance rather than attempting to manage the situation using disinfectant alone.
