Do your sheep need to be treated for lice at the coming shearing?

A routine treatment when no lice are present not only costs time and money, but also adds unnecessary chemical residues onto wool.

Checking sheep for lice a few weeks prior to shearing is good practice. Finding lice when they are present in low numbers is not easy, so a thorough method of searching is required, click here for details.

You can also use the LiceBoss Short Wool Lice Tool to see the probability that your sheep have lice.

This tool calculates the probability of having lice on this extensive list of factors:

  • State
  • Region
  • Regional Lice Prevalence
  • Time since last treatment
  • Long wool lice treatments
  • Whether you have you seen lice in these sheep
  • Any signs of rubbing
  • Lice present at last shearing
  • Probability of eradication if lice were present
  • Number of different sources of rams in the last 12 months
  • Number of different sources of ewes in the last 12 months
  • Number of sources of young sheep or wethers in the last 12 months
  • Number of neighbours with no lice
  • Chance of strays
  • Fence quality (worst section, not average)
