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.

How to apply Clik Pour-On

Clik Pour-on should be applied using the four stroke method as outlined below. It is recommended that Clik Pour-On is applied using the proper gun which features a fan spray nozzle. The gun can be found by clicking here.

The Four Stroke Method: The four stroke method ensures the pour-on is applied evenly by applying a quarter of the application at a time in four simple strokes.

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

4.5 Special precautions for use
Special precautions for use in animals:

The product is best applied before an anticipated blowfly challenge, or whena 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 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.
The use of CLIK has harmful effects on dung flies.
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.

Special precautions to be taken by the person administering the veterinary  medicinal product to animals:
 Operators should wear synthetic rubber gloves, a face mask and PVC trousers when applying 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 rinse eyes with clean water for several minutes and contact physician for advice.
 In case of ingestion call for medical advice.
 Always wash hands with soap and water after handling sheep and before eating and drinking or smoking.
 Wash hands and exposed skin after working with recently treated sheep.
 Do not eat, drink or smoke whilst using the product. Handling sheep in the weeks following treatment:
 Do not shear sheep in the 3 months after treatment.
 Handle sheep as little as possible after treatment as residues remain on the fleece for some weeks.
 If you need to handle sheep after treatment, wear coveralls and Wellington boots.

If sheep are wet also wear waterproof trousers and coat.

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 only accordingly to the benefit/risk assessment by the responsible veterinarian.
Laboratory studies in rats and rabbits have not shown any evidence or a 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.
CLIK is applied according to the following recommendations:
Body weight (kg)              Dose Volume (ml)
10-20                                   20
21-30                                   25
31-50                                   30
   >50                                   35

(Guide dose volumes correspond to 0.6 - 2 ml (30 - 100 mg dicyclanil) per kg bodyweight.)
Shake the container well before use.
CLIK 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.
Clik is administered once, before predicted Wohlfahrtia fly activity, or before or at the beginning of Lucilia fly activity. Clik will protect against blowfly strike caused byWohlfahrtia 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. 

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
An overdose of up to at least 5 times the recommended dose does not lead to any signs of local or systemic intolerance.
An antidote is not known.

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

Pharmacotherapeutic group:

Other ectoparasiticides for topical use.

ATC vet code:
QP 53AX24.

5.1 Pharmacodynamic properties
The mode of action of dicyclanil is not known but it is apparently similar to that of cyromazine, a triazine derivative. Similar to the Benzoylphenylureas (BPU) it interferes with moulting and pupation but without acting directly on the chitin synthesis.
Dicyclanil prevents the moult from the first to the second larval instar of Lucilia spp. and Wohlfahrtia spp.

5.2 Pharmacokinetic particulars
After 7 days post dosing, approximately 5% of the dose was absorbed and eliminated in urine and faeces.
Systemic absorption varies with such factors as wool density and length, and sheep breed.
Peak blood levels were observed between 12 and 48h post dose, accounting for <0.025 mg dicyclanil equivalents/kg. In experimental residue depletion studies, absorbed radioactivity was widely distributed throughout the body.
Highest 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.

Environmental properties:
The use of CLIK has harmful effects on dung flies.
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.

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. No pour-on or spot-on is effective against sheep scab.

The Four Stroke Method: The four stroke method ensures the pour-on is applied evenly by applying a quarter of the application at a time in four simple strokes.

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.
