Wondercide’s product is 98% naturally-derived, and it works to treat the entire lifecycle, from eggs to larvae, pupae and adults.
How does Wondercide work? It’s key active ingredients include:
- 90% cedar oil

Cedar oil is a potent, effective insecticide that affects octopamine, which is essential for regulating heart rate, behavior and movement. The oil blocks the octopamine neurotransmitter, which repels pests from the area. If insects come in contact with the spray, they suffocate and die.
Mammals don’t have octopamine neurotransmitters, so they’re not affected by the oil.
The jug includes a sprayer that makes it easy to apply this product. You can refill the jug when it’s empty so that you can continue using the sprayer. This product is both dog friendly and cat friendly.
The great thing about this product is that it’s ready to spray. There’s no need to dilute it, like with concentrate products. Simply buy it, attach the sprayer, and use as directed.
