Where there's a flea... an infestation could quickly follow



Just killing the fleas on your pets is not enough; 95% of the flea life cycle takes place in your pet’s bedding and home surroundings such as carpets, soft furnishings, etc.
To prevent re-infestation, you must break the life cycle. Johnson’s produce a range of effective flea control products, including household treatments, some containing IGR (Insect Growth Regulators) which help to prevent flea eggs hatching.

The Flea Problem: Fleas are small, brown, mobile insects which bite the skin and suck blood. They breed rapidly, often unnoticed and can quickly cause a major problem for pets. They can infest your home and will feed on humans.

Fleas & Your Pet:
Dogs and cats usually become infested from contact with other animals, including wildlife such as birds, rodents etc., particularly during summer and autumn months. Prompt treatment is necessary, as flea bites cause severe irritation and pets often become allergic to flea saliva, leading to inflamed skin, sores and loss of coat.

Signs Of Flea Infestation:
Constant scratching or biting of coat, twitching of back muscles, also skin and coat problems. Fleas and ‘flea dirt’ (tiny black droppings) may be seen when the coat is examined closely or combed out over damp paper, when a small reddish circle will form around the black spots. Flea bites on humans can be seen as small red spots up to 2.5cm (1 inch) apart.

Fleas In Your Home:
Fleas feed on dogs and cats, but spend most of their life cycle in pet bedding, carpets, rugs, furnishings, etc. A serious infestation can quickly occur in summer months and even in winter, in warm homes with central heating and fitted carpets.

Worms: Fleas are carriers of tapeworm eggs and are a major cause of worm infestation in dogs and cats - see back pages.

Life Cycle Of The Flea:
In warm conditions, the cycle can be completed in only 3 weeks, but may take up to 1 year or more. To prevent re-infestation, it is necessary to break the life cycle, which is in 4 stages:

Flea Life Cycle

Eggs: 50% of life cycle. Hundreds of eggs are laid, usually on pets, but fall off into bedding, carpets, furnishings, etc., where they soon
hatch into larvae.

Adult Flea: 5% of life cycle. Emerges from its cocoon when temperature conditions are
suitable, also in response to vibrations from pets or humans and jumps on to a host for the first of its meals. Eggs then start to be laid and the cycle begins again.
Larvae: 35% of life cycle. Larvae feed on organic matter (e.g., from flea droppings) then after a few days spin a cocoon and become pupae, hidden in the furnishings.


Pupae: 10% of life cycle. May develop into adult fleas in a week, but can remain in this stage for many months.
