When is peak flea season?

Peak flea season in the UK typically runs from late spring through early autumn, with July to September being the highest-risk months. Fleas thrive in warm and humid conditions, so the warmer summer months provide ideal breeding environments—especially in homes with central heating and pets.

Even though fleas are less active in winter outdoors, they can still be a problem indoors all year round due to heated homes.
