Fly Problem? No Problem?

Dectospot provides flexibility to farmers; as it has zero milk withdrawal in cattle and can be use during both pregnancy and lactation*.

During the key fly season, Dectospot is perfect for Irish farmers, who are looking for products which deliver efficacy, convenience and value.  

Fly control in the summer months is vital as nuisance flies reduce time grazing and lower productivity. Flies act as vectors for disease transmission and by reducing their contact with cattle for example, we can better control summer mastitis and new forest disease.

*Use only according to a benefit/risk assessment by the responsible veterinarian.
