Teagasc advises rechecking cattle two to three weeks after lice dosing
Lice thrive during winter because cattle grow thicker coats, which provide an ideal environment for infestation.
Now may be the time to recheck cattle two to three weeks after lice treatment.
Farmers are being advised to repeat treatment if necessary, as newly hatched lice may not have been killed by the initial dose. The advice comes from Teagasc beef specialist David Argue, who highlighted the importance of clipping and effective lice control in protecting cattle performance over the winter.
