Elanco AH have created an e-Form which is how you will report any blowfly complaints this year.

This can be done on your smart phone or on a PC, Laptop or iPad using the link below.

How it works:
When the form is completed we get the data instantly and log the details supplied, giving it a PV reference number. We then send an email to the reporter with the PV ref. and tell them an Elanco colleague will call the farmer to get further details and to investigate – this will be a member of our Pharmacovigilance team.

Prevention of blowfly strike on sheep caused by Lucilia sericata or Wohlfahrtia magnifica.

4.3 Contraindications
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

4.4 Special warnings for each target species
The veterinary medicinal 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.
It is recommended that animals with dirty back-ends are dagged or crutched prior to application.
If 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.

4.5 Special precautions for use
Special precautions for use in animals

Not applicable.

Special precautions to be taken by the person administering the veterinary medicinal product to animals Redness and irritation may develop after skin or eye contact with the product.
Contact with skin and eyes should be avoided.
Personal protective equipment consisting of synthetic rubber gloves and PVC trousers should be worn when handling the product.
In case of skin contact remove contaminated clothing and thoroughly wash the affected parts of the body with soap and water. In case of eye contact wash immediately with clean water. 
Always wash hands and exposed skin with soap and water after work.
Do not eat, drink or smoke whilst using the product.
Residues remain on the fleece for some time after treatment, therefore, it is good agricultural practice to minimise handling of sheep after treatment.
If you need to handle sheep within 3 months after treatment, wear synthetic rubber gloves and long trousers or coveralls.
If sheep are wet wear waterproof trousers.
Do not shear sheep in the 3 months after treatment.

Other precautions
Treated sheep must be kept away from watercourses for at least one hour after treatment.
There is a serious risk to aquatic life if this advice is not followed.

4.6 Adverse reactions (frequency and seriousness)
None known

4.7 Use during pregnancy, lactation or lay
The safety of the veterinary medicinal product has not been established during pregnancy or lactation. Use according to the benefit/risk assessment by the responsible veterinarian. Laboratory studies in rats and rabbits have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects.

4.8 Interaction with other medicinal products and other forms of interactions
None known.

4.9 Amounts to be administered and administration route
For external use only.
The veterinary medicinal product is applied according to the following recommendations:
Guide dose volumes correspond to 0.6 – 2 ml [39 – 130 mg dicyclanil] per kg bodyweight.)
To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.
If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or overdosing.
Recommended for treatment in sheep with any wool length, including off-shears.
Shake the container well before use.
Do not dilute with water.
The veterinary medicinal product must be applied with a manual or automatic dosing gun, fitted 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 bands 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. 
The veterinary medicinal product should be applied before, or at the start of, predicted fly activity. The veterinary medicinal product will protect against fly strike for 19 weeks. It is good agricultural practice to check animals regularly for fly strike.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
An overdose of up to at least 4 times the recommended dose does not lead to any signs of local or systemic intolerance. No antidote is known.

4.11 Withdrawal period(s)
Meat and offal: 40 days
Not authorised for use in animals producing milk for human consumption.

Pharmacotherapeutic group:

Other ectoparasiticides for topical use.

ATC vet code:

5.1 Pharmacodynamic properties
Dicyclanil prevents the moult from the first to the second larval instar of Lucilia sericata and Wohlfahrtia magnifica.
It is less effective against later larval stages and does not have any adulticidal action.
The mode of action of dicyclanil is believed to be similar to that of the triazine compounds.

5.2 Pharmacokinetic particulars
In studies with the 50 mg/ml formulation, after 7 days post dosing, approximately 5 % of the dose was absorbed and eliminated in urine and faeces.
Peak blood levels were observed between 12 and 48 hours post dose, accounting for < 0.025 mg dicyclanil equivalents/kg.
In experimental metabolism studies, absorbed drug was widely distributed throughout the body.
Longest half lives were found in liver and kidney being 13 and 10 days respectively.
In muscle, fat and wool, unchanged dicyclanil was found to be the major residue, whereas in liver and kidney the descyclopropyl dicyclanil was found to be the major residue together with unchanged dicyclanil.

5.3 Environmental properties
Dicyclanil has the potential to cause harmful effects on aquatic invertebrates and dung fly larvae.
Following use of this product, levels of dicyclanil potentially harmful to dung fly larvae have been shown to be excreted in faeces for approximately 4 weeks.
Faeces from treated animals may temporarily reduce the abundance of dung fly larvae which may impact on dung degradation.

Sheep Pour-ons and spot-ons
Pour-ons and spot-ons need to be applied accurately and each manufacturer may recommend subtle differences. Use appropriate and calibrated guns, always clean with warm soapy water and then rinse after use.
Store in a safe dry place.
When treating sheep with these products, make sure they are applied along the back line.
If placed to one side, the product will not spread evenly around the body.

1) 1/4 applied from between the shoulders to middle of back
2) 1/4 applied from middle of back to top of animals tail
3) 1/4 applied from one side of the animals tail down the crutch
4) 1/4 applied from other side of tail down the other crutch



Blowfly is the main external parasite traditionally affecting sheep in the late spring and summer months. Changing weather patterns have resulted in an increasingly unpredictable and lengthening season. Blowflies are attracted to lay their eggs on areas of soiling or damage (wounds) on the animal, or on carcasses. Therefore, the key to blowfly control is to minimise breeding opportunities by:

  • Managing deadstock: remove deadstock as quickly as possible, and keep deadstock covered while waiting for collection.
  • Managing flock health:  minimise faecal soiling through good worm control and fleece management, and through treating wounds, including foot infections.
  • Using a preventative treatment early in the season: prevent established blowfly strike in the flock to protect the sheep and to prevent those first waves of flies from breeding. Doing this will massively reduce blowfly numbers, and strike risk, later in the season.
