What disinfectant is best for spraying walls after every batch?

First, clean the house, then wash with water. Mix caustic soda in warm water (20-30g per liter) and wash the pen with it. It helps to break down and loosen organic matters and dirt. But it is not very good in killing germs. Leave for 1 hour and rinse thoroughly. NB: Caustic soda  is corrosive. Wear protective clothing, boots and glasses
After rinsing off caustic soda, spray everything with  one of these broad spectrum disinfectant

Phenolic disinfectant (e.g., cresol, carbolic acid) – very effective on walls.
Formalin (2–4%) – very strong, but use with good ventilation.
Hydrogen peroxide + peracetic acid – eco-friendly and powerful.
Iodine-based disinfectant – good general-purpose spray.
Spray evenly on walls, floors, and equipment until surfaces are well-wetted.

Downtime (Rest Period)
Leave the poultry house empty for 10–14 days.
Sunlight and dryness will help kill remaining pathogens.
