- Each year 27% of wool producers experience
a lice infestation.
- 35% will fail to eradicate the lice within
12 months.
- Sheep lice attract higher treatment costs
and cause production losses of up to
$12 per
head.*

Invest in prevention
- A lice infestation can cost a farmer between
$5 and $12 per head in
lost production.
- A Zapp lice treatment is on average just
$0.48 per head per dose.
- If a producer had 2000 sheep he risks a potential
loss of up to $24,000 whereas
an investment
of just $960 in a Zapp treatment would prevent
this.
