Do shampoos kill fleas?
Yes. Any soapy water kills fleas. But once bathed, shampoos won’t keep the fleas off your pets. That’s why you need to add Flea Treats to your pet’s routine. Keep those fleas off your pet no matter where you take it. And if you rinse the shampoo properly, no shampoo, insecticidal or not, will provide residual relief from fleas.
