treatment may therefore be required, depending on the level of fleas in the
environment. To aid reduction in environmental challenge, the additional use of
a suitable environmental treatment against adult fleas and their developing
stages is recommended. In order to reduce further the environmental challenge,
it is recommended that all dogs, cats and rabbits in the household are treated
with a suitable product.
If there are several pets in the household, it is advisable to treat all pets at the
same time. Fleas can be detected by parting pet's coat and examining skin for
signs of flea activity or by combing coat with a fine-toothed flea comb. Frequent
scratching or excessive grooming can also be signs of flea infestation. Fleas
from pets often infest pet's basket, bedding and regular resting areas, such as
carpets and soft furnishings which should be vacuumed regularly and treated
periodically with an insecticide suitable for household use, preferably containing
an I.G.R. (Insect Growth Regulator) to control flea egg development and help
break the flea life cycle. Wash and change pet bedding regularly.
The product remains effective if the animal becomes wet, for example after
swimming or exposure to heavy rain. However, in cases of frequent swimming
or bathing re-treatment may become necessary, depending on the presence of
fleas in the environment. In these cases do not treat more frequently than once
weekly.
In case of biting louse infestation, the animal should be re-examined 30 days
after treatment as some animals may require a second treatment.
If signs of disease persist or appear, consult a veterinary surgeon

After application, do not stroke or groom pets until application site is dry.
It is therefore recommended that animals are not treated during the day,
but should be treated during the early evening, and that recently treated
animals are not allowed to sleep with owners, especially children.
If the product gets into eyes accidentally, the eyes should be thoroughly
rinsed with clean water. If skin or eye irritation persists, or the product is
accidentally swallowed, obtain medical attention, showing the package
leaflet or carton to the physician.
Wash hands thoroughly after use.
In order to prevent children from getting access to pipettes, keep the
pipette in the original packaging until ready for use and dispose of used
pipettes immediately.
iii. Other precautions
Imidacloprid is toxic to aquatic organisms. To avoid adverse effects on
aquatic organisms, treated dogs should not be allowed to enter water
courses for 48 hours after treatment.
Keep treated pets away from materials such as leather, soft furnishings,
plastics, etc until site of application is completely dry as contact may
damage these surfaces.
