Why protect against fleas
Fleas are a big problem...
The Big Flea Project found that 1 in 4 cats and 1 in 7 dogs1 selected at random, visiting their vets, were found to be carrying fleas.
Wider implications

Wider implications
Fleas can cause severe irritation leading to infection of the skin (flea allergy dermatitis). They may also carry Bartonella - this is a bacteria that causes the disease Bartonellosis, also known as Cat Scratch Disease.
The Big Flea Project1 results showed that 11.3% of fleas were carrying this disease that can affect both dogs and humans if exposed to infected fleas or flea dirt.
Cat Scratch Disease can cause swollen lymph nodes and fever in people and can be particularly dangerous for people with lowered immune systems.
As well as diseases, fleas can carry the flea tapeworm which can cause harm to our pets, and has been known to infect humans too.
Finding the right solution

Finding the right solution
Treatments available on prescription from your vet include spot-ons, chews and sprays.
Prescription products last from 28 days to 12 weeks, and spot-ons can work topically (from the outside) or systemically (from the inside), and collars are also available that last up to 6-8 months.
If you have a flea infestation, then to break the flea life cycle you’ll need a minimum of three doses, given on time, of the 28-day and 35-day products; or one dose of the 12-week product. Continuing with treatment all year round will help to prevent re-infestation.2

Fleas and ticks can easily infest to your pet. By the time most owners notice fleas they have already infested their home and ticks have been feeding for a week or more.
These parasites can also carry diseases that can be detrimental to your pet’s health.
By consulting with your vet and getting vet recommended parasite protection you will be giving your pet the best possible protection against fleas and ticks.
Animals react differently when bitten by fleas or ticks.
The following are some signs to look-out for, but keep in mind that your pet might not necessarily display these, so the best way to ensure your pet doesn't have any fleas or ticks is to speak to your vet about products to protect them.
- Mild to severe skin irritation
- Intense scratching and biting of skin
- Hair loss
- Skin infections

The effects of temperature on fleas
Fleas cannot withstand dramatic temperature changes – but they don’t have to when they’re living in our homes.
• Pet bedding and dens provide protection for flea larvae from low humidity and extreme fluctuation in temperature
• Larvae temperature needs: 13-35°C and humidity >50%
• Larvae are photophobic (extreme sensitivity to light) and geotactic (moving in response to the force of gravity): they move to the base of carpets where they’re protected
• Adult fleas can survive for a number of days without feeding
• Flea pupae can survive in their cocoon for up to 12 months if temperatures are low
So, fleas will survive if it’s cold outside!
Fleas are active
Fleas can't survive for long outdoors if it is cold. However, central heating in houses will create the optimal temperature for fleas to lay eggs and feed, increasing the chances of an infesation in households.
