A large number of fleas and flea problems have increased this season in the northern beaches area. The particularly wet and humid conditions we’ve been experiencing this season has been perfect for flea eggs (which can lay dormant for years) to hatch, increasing the number from last year. As hopefully you know, these conditions are also perfect for ticks which again, have had a bumper year. I have had many cat and dog clients really struggling to combat these persistent pests.
Here are some flea factsheets and advice from Pittwater Animal Hospital which I hope you find useful:
