Sarcoptic mange (Sarcoptes scabiei var suis) is a parasitic disease caused by mites and is characterised by papules and marked pruritis. The sarcoptic mange mite’s entire life cycle (egg, larva, nymph and adult) occurs beneath the skin and the mites and eggs cannot survive away from this environment for very long.

Sarcoptic mange can be treated with three injections of diazinon, triazophos or amitraz with intervals of seven days between injections. (The three injections and seven day intervals are crucial!) A macrocyclic lactone (avermectin injection of 1 ml per 33 kg of avermectin in the feed for seven days) can also be administered.

Disinfecting pigsties

It is preferred that your pigs are not inside their housing while you clean and disinfect the area.

• The first thing to do is to remove all organic matter from the pen – especially bedding and manure.
• Wash with soap and water – preferably using a degreasing soap and isn’t damaging to the environment and is registered for animal use that will remove any biofilm in the area.
• Rinse the area with a pressure sprayer.
• Disinfect the area with a registered disinfectant.
• Allow the area to dry bout for one week, if possible.
• It’s very important to ensure that the soap and disinfectant you use is compatible with animals and is registered for animal use.
• Consult your veterinarian to assist you in choosing the right products for your needs.
