Treatment Methods

Poultry Red Mites and Northern Fowl Mites can move from flock to flock via shipping crates, clothing and wild birds, making them difficult to control. Current methods for managing Poultry Red Mites lack sufficient efficacy to keep infestations under control in many poultry farms. 1

Chemical control is a common treatment method. Spraying the local environment – walls, floors, roosts, nest boxes and birds- is common, but may lead to the following complications:

  • Short residual activity 2
  • Inability to reach cracks and crevices where mite colonies are located
  • Little or no effect on mite eggs, thus enabling regrowth of infestation burdens
  • Risk of feed contamination
  • High costs of labor and worker protection equipment
  • Egg and meat withdrawal periods following treatment
  • Mite resistance development 3

The Financial Burden of Poultry Red Mites

Poultry Red Mites are not only destructive to the health of your flock – they also reduce productivity, causing millions of dollars of loss across the poultry industry.

Breakthrough Solutions

The latest innovation in parasiticide for chickens provides proven results against Poultry Red Mites and Northern Fowl Mites. Because it is administered through drinking water, it provides fast, convenient and potent results, with proven safety for poultry and product users.

The recommended treatment regimen of two doses, seven days apart via drinking water offers near-total elimination of mite populations in treated poultry houses – across layer, breeder and/or pullet houses. Better yet, the recommended treatment regimen spans two mite life cycles, killing mites with above 99% efficacy.

When combined with proper biosecurity measures, Exzolt combats mite resistance and helps achieve long term treatment of mite populations in poultry houses.

Mite Surveillance

There are many methods for monitoring mite infestations that can detect first mites, record population dynamics and help determine when to treat and the effectiveness of treatment. Mite traps are a very effective way for monitoring Poultry Red Mites. Want to know more? Provide your email and an MSD Animal Health representative will get in touch with you.
