Flea Treatments in the Home: What Happens After They're Applied? with Dr Tilly Collins

Where do flea and tick treatments really go?For many of us, protecting our dogs from fleas and ticks has become part of responsible care. But what happens when the products we use to protect our dogs raise wider questions about environmental health, scientific uncertainty and the choices we make every day?In this thought-provoking conversation, I'm joined by Dr Tilly Collins, Senior Fellow & Deputy Director of Imperial College London's Centre for Environmental Policy, whose research is transforming our understanding of how flea and tick pesticides move beyond the animals they're applied to.Together, we explore what happens after these products are used, how residues have been found not only in rivers and waterways but within our homes, and why this is opening up important new conversations about parasite management, environmental responsibility and the need for further research.Rather than offering simple answers, this episode invites us to ask better questions.Because perhaps the future of parasite management isn't about eliminating every risk—it's about understanding risk more deeply and making thoughtful, evidence-informed decisions for the individual dog in front of us.In this episode we discuss:Why flea and tick control is far more complex than many of us realiseHow modern flea and tick pesticides workWhat Dr Collins' research has revealed about pesticide residues in homes, including household dust, mop water and dog beddingWhether fleas may be developing resistance to some commonly used productsWhat we really mean when we talk about "risk"How to move towards a more personalised, risk-based approach to parasite managementThe need for further independent research into the long-term impacts on animals, people and the environmentHow we can begin shifting from routine intervention towards thoughtful stewardshipResources🐾 Download my free Mystic Dog Mama Low-Tox Parasite Prevention ToolkitLearn how to assess your dog's individual parasite risk and explore practical strategies for creating a balanced, integrated approach to parasite management.👉 https://mysticdogmama.com/the-81-percent🌿 Join The Nourished PackCome and continue the conversation with a community of thoughtful dog guardians exploring holistic canine care together.👉 https://facebook.com/groups/thenourishedpackConnect with me on Instagram https://instagram.com/mysticdogmamaConnect with Dr Tilly CollinsSenior Fellow & Deputy DirectorImperial College London's Centre for Environmental Policyhttps://profiles.imperial.ac.uk/t.collins/aboutEnjoyed this episode?If you found this conversation valuable, please consider:⭐ Leaving a review🎙️ Following the Mystic Dog Mama Podcast📤 Sharing this episode with another dog loverThe more we can create space for thoughtful, evidence-informed conversations, the better equipped we'll all be to care for our dogs—and the wider living world they're part of.DisclaimerThis podcast is intended for educational purposes only and should not be considered veterinary advice.
