Rodent control on a poultry farm: programme, documentation, and DDD records
Rodents carry Salmonella, destroy feed, and damage installations. Learn how to build an effective rodent control programme and why DDD treatment records are critical for biosecurity and audits.

Why are rodents a threat on a poultry farm?
Mice and rats are one of the most serious disease vectors on a poultry farm. They carry Salmonella (S. Typhimurium and Enteritidis) — a pathogen particularly dangerous to broiler and layer flocks — as well as Leptospira and other zoonotic bacteria. Rodents enter poultry houses through gaps, eat and contaminate feed, and damage electrical cables and insulation. It is estimated that a single pair of rats and their offspring can consume or contaminate several hundred kilograms of feed per year.
Economic and sanitary losses from inadequate rodent control
Without rodent control, production results suffer directly: worse feed conversion, higher mortality, risk of a Salmonella outbreak, and potentially mandatory flock culling. In HACCP audits and QAFP quality systems, the absence of a documented rodent control programme is a non-conformity that blocks certification or leads to a batch being rejected. Rodent control is not just hygiene — it is real income protection.
Rodent control and biosecurity regulations
Rodent control is required as part of poultry farm biosecurity under national and EU legislation (EU Regulation 2016/429 — the Animal Health Law). The Veterinary Inspection and certification bodies check whether a farmer has a current rodent control plan and records of DDD treatments carried out. Treatments may be done by farm staff or by a licensed pest control company. In either case, records must be kept accurately. More on the legal framework: Poultry farm biosecurity.
Connection with cleaning, disinfection, and Salmonella
Rodent control is the third pillar of the DDD programme (disinfection, pest control, rodent control). It works best when coordinated with poultry house cleaning and disinfection after flock removal and with building sealing before restocking. Failures in rodent control are one of the main reasons Salmonella is found in swab samples during official flock testing.

What rodents do on a poultry farm — 5 specific threats
The consequences of a rodent presence go far beyond visible damage.
Spreading Salmonella and Leptospirosis
Rodents are asymptomatic carriers of Salmonella spp. and Leptospira interrogans. Their droppings and urine contaminate feed, water, and litter, directly affecting the results of official bacteriological flock testing.
Feed losses and resource contamination
A single adult mouse eats 3–4 g of feed per day but destroys many times more by contaminating it with droppings and urine. On large farms, uncontrolled rodent populations generate feed losses of hundreds of kilograms per month.
Installation damage and fire risk
Rodents gnaw electrical cables, water pipes, and thermal insulation, causing failures in heating, ventilation, and automatic feeding systems. Damaged cables are a frequent cause of poultry house fires.
Entering the poultry house through gaps
A mouse can squeeze through a 6 mm gap; a rat through a 20 mm gap. Unsecured ventilation openings, gaps around pipes and cable entries are permanent migration routes between farm buildings and poultry houses.
Carrying ectoparasite vectors
Rodents are a reservoir for poultry red mite (Dermanyssus gallinae) and fleas, which transfer to the birds and cause flock stress, anaemia in layers, and reduced production indices.
Risk in HACCP and QAFP audits
An absence of up-to-date DDD treatment records is one of the most common non-conformities found during quality system audits. It results in a corrective action requirement or even suspension of the certificate.
How to build an effective rodent control programme on a poultry farm
Effective rodent control is not a one-off treatment but a continuous monitoring and control system.
Bait station placement map
Draw a site plan of the farm and mark all rodenticide placement points — bait boxes and control stations. Each point should have a number that appears in the records. Place bait stations along building walls (rodents travel along walls), near feed storage, at poultry house entrances, and around cable conduits.
Bait boxes and control stations
Use closed, secured bait boxes that restrict access for birds and domestic animals. Anchor boxes to the floor or wall so they cannot be moved. Check the consumption level regularly — rapid depletion signals active rodent presence.
Selecting approved rodenticides
Use only rodenticides included in the Register of Biocidal Products authorised in Poland (URPL). The most commonly used active substances are bromadiolone and brodifacoum (2nd generation) or coumatetralyl (1st generation). Always check the label for approval for use in the presence of livestock.
Inspection schedule for bait points
Set an inspection schedule for bait stations — every 7–14 days during the active season, every 30 days off-season. Record the inspection date, point number, product status, and observations (tracks, droppings, damage). Regularity of inspection matters for effectiveness and for auditors.
Building sealing
Chemical rodent control works better when you limit entry points. Before every restocking, inspect walls, foundations, and ventilation openings. Fill gaps larger than 6 mm with mortar or steel mesh — rodents will gnaw through polyurethane foam.
Working with a pest control company
Large farms or farms with recurring problems should contract a licensed pest control company. The company carries out a survey, lays out the map, performs treatments, and issues a protocol. Pest control protocols are valid documentation in HACCP/QAFP audits — keep them for at least 3 years.
Frequently asked questions about rodent control on a poultry farm
How often should rodent control be carried out on a poultry farm?add
The minimum is two rodent control treatments per year (spring and autumn), but on active poultry farms a continuous monitoring programme with bait station checks every 7–14 days is recommended. If rodent activity is detected, increase inspections to weekly until the population is eliminated.
Which rodenticides should be used on a farm?add
Use only rodenticides authorised for sale in Poland — listed in the Register of Biocidal Products of the URPL. The most commonly used active substances are bromadiolone and brodifacoum (2nd generation) or coumatetralyl (1st generation). Always check the label for approval in the presence of livestock.
What should DDD treatment records contain?add
DDD records should include: the date of the treatment, the type and quantity of product used (batch number, registration number), a map or list of bait points, the person responsible for the treatment, and inspection results (consumption, observations). For contracted services, this is the pest control company's signed and stamped protocol.
Do I need to hire an external pest control company?add
No — a farmer may carry out rodent control using commercially available products. However, thorough records are mandatory. A licensed pest control company is required only when a producer or certification auditor demands professional confirmation in the form of a protocol issued by a registered pest control operator.
How does rodent control relate to Salmonella testing?add
Rodents are the main Salmonella reservoir on a farm. A documented, active rodent control programme is one of the pieces of evidence a farmer can present if Salmonella is found in an official flock test. The absence of rodent control when a positive result is recorded makes it virtually impossible to defend against administrative consequences.
How does DlaFerm.pl help with DDD records?add
DlaFerm.pl lets you record hygiene and DDD treatments directly in the app — with date, product description, and assignment to a specific building. The full history is available during a veterinary inspection or HACCP audit without needing to hunt through paper logbooks.
