With Wondercide, there is no need to use chemical pesticides to kill fleas & ticks! Pets + Home kills adult fleas & ticks, and the eggs will never hatch after exposure. For best results, use Pets + Home on your pet as a treatment to kill adult pests and eggs as needed, and apply as a preventative when you're going to untreated areas (like on a walk or to the dog park) the same way you apply bug spray to yourself when you know you're going to be exposed to mosquitoes.

The science sounded iffy to me at first, but I can tell you they really work and are well worth the price.

The onset of signs that your dog has been poisoned by a topical, dip, oral, spray, or collar flea and tick medicine can range from a few hours to a few days. When you use a substance containing an ectoparasiticide on your canine family member, always record the amount, day, and time of use. A reaction can occur at any time, even if your pet has had the product used on him before.
