No The Bonide MoleMax RTS will not harm your lawn or flowers, it will only coat plants that it is applied to.
Bonide MoleMax RTS repels moles, voles, skunks, armadillos, rabbits, and gophers using castor oil, an all natural solution. It does not kill anything.
The MoleMax RTS product label recommends that you apply to the entire area. If you have a large area to treat, it is best to treat in sections, beginning at one point and working toward a desired "exit location."
Bonide MoleMax RTS is 100% castrol oil, but it is not OMRI certified.
Bonide MoleMax RTS would be a great repellent. However, if you want to use bait, we would recommend using Kaput Rat & Mouse Bait. It imitates the natural food of rats, mice, and voles. The place packs can be placed whole in areas where the rodents feed. Warfarin, the active ingredient, is an anticoagulant that is effective at very low dosages and because of this is considered a low-risk bait with very low secondary and environmental toxicity.
