Dicyclafly 5% Pour-on Suspension for Sheep — SPC Details
Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.
Prevention of blowfly strike due to Wohlfahrtia magnifica on sheep.
Dicyclafly 5% Pour-on Suspension for Sheep is applied according to the following
recommendations:
Body weight (kg)Dose Volume (ml)10-202021-302531-5030>5035
(Guide dose volumes correspond to 0.6 – 2 ml (30 – 100 mg dicyclanil) per kg bodyweight.)
Shake the container well before use.
Dicyclafly 5% Pour-on Suspension for Sheep must be applied with a manual or automatic
dosing gun (e.g. Elanco Pour-on gun), with a spray nozzle, which guarantees the correct
spreading of the product on the fleece. Best results will be achieved by holding the gun
approximately 45 cm from the sheep during application. Apply as a fan spray along the spine
of the animal in a band at least 10 cm wide from the middle of the shoulders and in an arc
around the crutch and tail. Half the dose should be applied along the spine with the remainder
over the tail and crutch area.
Dicyclafly 5% Pour-on Suspension for Sheep is administered once, before predicted
Wohlfahrtia fly activity, or before or at the beginning of Lucilia fly activity. Dicyclafly 5% Pour-
on Suspension for Sheep will protect against blowfly strike caused by Wohlfahrtia or Lucilia
flies for 16 weeks. In individual cases, a strike may occur earlier; therefore, it is good practice
to check animals regularly for blowfly strike.
Do not shear sheep in the 3 months after treatment.
Do not use in case of hypersensitivity to the active substance or any of the excipients.
i) Special precautions for use in animals
The product is best applied before an anticipated blowfly challenge, or when a blowfly
challenge is identified on or in the vicinity of the farm. Established strikes may require a
separate treatment with a knockdown insecticide.

dagging or crutching is undertaken in the weeks following application, these animals should
be re-treated, otherwise protection could be lost.
Do not apply during heavy rainfall, or when such conditions are expected. The resulting wash
out may reduce the protection period.
The use of Dicyclafly 5% Pour-on Suspension for Sheep has harmful effects on dung flies.
