PetraMax Castor Oil Mole Repellent (135 fl oz)
The PetraMax 135 fl oz castor oil formula is a natural solution designed to deter moles and voles by affecting their feeding habits through scent and taste. The formula emphasizes pet safety and biodegradability, making it suitable for lawns where children or pets play. It is marketed as a potent option with a focus on castor oil’s natural properties to disrupt mole and vole foraging behaviors. Application guidance emphasizes coverage and repeat treatments for ongoing deterrence, with emphasis on safe, garden-friendly use.
PetraMax Castor Oil Mole Repellent (33.8 fl oz)
This 33.8 fl oz version mirrors the natural, pet-safe castor oil approach, designed for smaller lawns or targeted treatment. It emphasizes a stronger active castor oil presence per ounce, aiming to provoke adverse feeding cues in moles and voles. The product highlights biodegradability and safety for outdoor spaces, with practical application steps to maintain a mole-free zone over time while limiting impact on beneficial soil organisms.
Baar MolEvict Lawn Mole Castor Oil (1 gallon)
MolEvict is a professional-grade castor oil solution designed to repel moles and voles by creating an unfavorable environment around turf and plant roots. The product emphasizes concentrated strength and a distinctive odor or texture that discourages digging. Marketed for lawns, gardens, and landscapes, MolEvict aims to drive pests away by targeting their food sources and scent cues, offering an approach that minimizes chemical exposure while focusing on deterrence.
Scotts GrubEx1 Season Long Grub Killer (4 months, 5000 sq. ft.)
GrubEx1 is a season-long grub killer designed to protect lawns by targeting grubs when they are young, with claims of up to four months of protection on a 5,000 square foot area. Since grubs can attract moles by feeding on grassroots and thatch, reducing grub populations can indirectly reduce mole activity. The product also notes control of related pests like armyworms and chinch bugs, making it a broader lawn pest management option for homeowners dealing with overlapping pest pressures.
Buying Guide: Key Considerations For Mole Control On Lawns
When selecting a lawn treatment to address mole activity, consider these factors to balance effectiveness, safety, and environmental impact.
- Trigger mechanism and target pests: Natural repellents relying on scent and taste (castor oil-based products) deter moles without killing them, while bait products (such as mole and gopher baits) aim to reduce population directly. Decide whether deterrence or population reduction best fits your yard.
- Safety for pets and children: Look for pet-safe labels and biodegradability. Castor oil products often claim low risk when used as directed, but always follow application instructions and keep treated areas away from play zones.
- Lawn health implications: Reducing grubs can lower a mole food source, but grub control products should be used according to label directions to avoid negative effects on beneficial soil organisms and turf.
- Coverage and application frequency: Assess square footage coverage and whether the product requires single or repeated applications. Season-long formulations may provide extended protection but require proper timing to match pest life cycles.
- Environmental conditions: Temperature, rainfall, and soil type influence product performance. Some deterrents may be less effective during heavy rain or extreme heat, so plan treatments accordingly.
- Integrated approach: Combining deterrents with lawn maintenance—such as proper watering, mowing height, and aeration—can improve turf resilience and reduce mole-friendly conditions.
- Non-target considerations: While targeting moles, consider potential impacts on beneficial wildlife and worms. Some products may affect soil invertebrates if misapplied.

Notes On Use And Safety
Always read and follow the specific product label for application rates, timing, and safety instructions. For deterrents, apply around the yard perimeter and known mole activity zones, reapplying as directed, especially after heavy rainfall. For bait products, place in active burrows only and adhere to local regulations regarding pest control methods. If mole activity persists or expands, consider consulting a lawn care professional to assess underlying soil and moisture conditions that invite burrowing pests.
