Best Castor Oil For Gophers: Compare 10 Repellent Options

#1 · Best Overall

1. Natural Elements Lawn Repellent

• Form: Oil

Best for: Large lawn treatment.

Why it ranks #1: Its 100% castor-oil lawn treatment specifically lists gophers among target pests and comes in a 128-ounce size for outdoor use.

A 128-ounce jug of 100% castor oil formula gives this Natural Elements treatment a larger supply for lawns and landscaped areas. Its listed repellent use includes gophers alongside moles and voles, making it a direct option for buyers treating burrowing-pest activity across outdoor spaces.

The oil-form formula is intended to disrupt moles’ and voles’ sensory perception, and verified product information also lists gophers among the animals it can help evict. For application, the directions describe mixing one cup of repellent and half a cup of liquid dish soap in a one-gallon lawn sprayer, then adding water. That sprayer-based process suits buyers able to prepare and apply a diluted lawn treatment; the gallon container supplies more concentrate than a small bottle.

Skip it if you want ready-to-spread granules; Victor Mole and Gopher Repellent comes in granule form.

Choose this for gopher, mole, or vole activity when you can mix a liquid treatment for lawn-sprayer use and want a gallon of concentrate. Its application involves preparation rather than scattering granules directly.

#2 · Measured Coverage

2. Baar MolEvict

• Weight: 2.14 lb

Best for: Concentrated lawn coverage.

Why it ranks #2: This liquid castor-oil repellent names gophers and specifies that its 32-ounce bottle covers 5,000 square feet.

Baar MolEvict pairs a 32-ounce bottle with stated coverage of 5,000 square feet, giving lawn owners a defined area to plan around. Its castor-oil repellent is listed for moles, voles, gophers, and armadillos, making the product directly relevant to burrowing pests.

The concentrated formula is described as using castor oil’s scent, texture, and composition to encourage unwanted animals to leave. Directions call for mixing one cup of MolEvict with one cup of unscented, biodegradable liquid dish soap in a garden hose sprayer, then spraying the active area. The 5,000-square-foot coverage figure helps estimate treatment scale, while the hose-sprayer method means buyers should expect a mixing step before application rather than a ready-to-use pour.

Skip it if you prefer granules that penetrate soil with water; Tomcat Mole & Gopher Repellent Granules use Ground Penetrating Technology.

A practical match for buyers treating a defined lawn area who can prepare a hose-sprayer mixture. The stated coverage helps with planning, but this is a concentrated liquid, not a ready-to-apply granular treatment.

#3 · Granule Format

3. Victor Mole and Gopher Repellent

• Form: Granule
• Weight: 10 lb
• Volume: 10
• Material Features: Natural

Best for: Granules for active tunnels.

Why it ranks #3: The 10-pound granules explicitly target gophers and use castor oil to make tunnel surroundings unpleasant to burrowing animals.

Victor’s 10-pound castor-oil granules use a tunnel-penetrating formula intended to carry the product into burrows. The listing targets gophers, moles, voles, and armadillos, offering buyers who favor a dry application an alternative to mixing liquid castor oil.

The granules are described as absorbing into the ground so they can reach tunnels, while the dual-action formula makes the tunnel environment smell and taste unpleasant to burrowing animals. This form changes the workflow from preparing a liquid mixture to identifying active areas and applying granules. Product directions say to avoid treating the entire lawn in one application, so buyers should plan a targeted approach rather than blanket coverage. The 10-pound bag supplies a substantial amount for that staged strategy.

Skip it if you want a smaller granular bag with stated 4,000-square-foot coverage; Tomcat Mole & Gopher Repellent Granules are a 4-pound option.

Choose Victor if you want a larger granular supply and plan to focus on active burrowing areas over staged applications. The directions rule out treating the whole lawn at once, so it calls for a targeted approach.

#4 · Defined Coverage

4. Tomcat Mole and Gopher Granules

• Form: Granules
• Weight: 4 lb

Best for: Measured granular lawn use.

Why it ranks #4: These castor-oil granules name gophers and state that a 4-pound bag covers up to 4,000 square feet.

Tomcat’s 4-pound granule bag lists coverage of up to 4,000 square feet, helping lawn owners relate the package to a defined treatment area. Its Ground Penetrating Technology is intended to help castor oil mix with water and penetrate soil for burrowing-pest control.

The granules are listed for moles, gophers, voles, armadillos, and other burrowing pests, while the ground-penetrating formulation supports soil absorption when water is present. That pairing makes this a dry product intended to work through the soil, rather than a liquid that must be blended in a sprayer. The stated coverage gives a planning reference for a single bag. The supplied information advises identifying active runways before treatment, which helps focus application on affected areas.

Skip it if you need a 10-pound granular supply for a targeted staged strategy; Victor Mole and Gopher Repellent comes in a 10-pound bag.

A good fit for buyers who want granular application with a stated area per bag and can identify active runways before treating. Its 4-pound package is the boundary to keep in mind for larger lawns.

#5

5. Nature's MACE Mole Repellent

• Form: Oil
• Weight: 2 lb
• Volume: 32 fluid oz
• Material Features: Non Toxic

Best for: All-season liquid treatment.

Why it ranks #5: The 32-ounce liquid lists gophers among its target pests, identifies castor oil as its ingredient, and provides mixing directions.

Nature’s MACE describes its 32-ounce castor-oil formula as water-activated and effective in all seasons, setting it apart for buyers planning year-round lawn care. Verified product information includes gophers among the target animals, along with moles, voles, and armadillos.

The formula is listed as 100% castor oil, and its stated action is to taint a food source and leave an unpleasant smell for moles and voles. Water activation and time-release claims support an all-season positioning, while the directions give a specific preparation process: combine castor oil and dish soap, then mix several tablespoons of that blend with a gallon of water. This makes it a liquid treatment that requires measuring and dilution before use, rather than a ready-spread product.

Skip it if you prefer granules without a liquid dilution step; Tomcat Mole & Gopher Repellent Granules use a dry application form.

Choose this if an all-season, water-activated liquid fits your gopher and other burrowing-pest treatment plan. Be prepared to measure and dilute the castor oil mixture; it is not a ready-to-spread granular option.

#6

6. Petra Castor Oil Repellent

• Form: Oil

Best for: Petra castor-oil formula.

Why it ranks #6: This 33.8-fluid-ounce outdoor repellent describes a castor-oil formula for gophers, though the listing gives no coverage figure.

PetraMax lists a castor-oil formula with three times the active ingredients of other castor-oil mole products, its most specific differentiator. The 33.8-fluid-ounce oil is promoted for moles, gophers, and voles, giving yard owners a targeted liquid option for burrowing pests.

The listing identifies a 100% castor oil natural formula and describes it as pet-safe, while naming moles and gophers in its intended yard use. At 33.8 fluid ounces, it is a smaller liquid container than gallon-format products, which may suit buyers who do not need a large supply. The product page does not provide a mixture ratio or coverage figure in the supplied facts, so treatment planning is less explicit than with products that state those details.

Skip it if you need a stated coverage area and mixing instructions; Baar MolEvict lists 5,000 square feet and hose-sprayer directions.

This is a fit for buyers seeking Petra’s castor-oil liquid for yard pests and preferring a 33.8-ounce size. Its listing makes broad efficacy claims, but offers limited supplied guidance for calculating or preparing an application.

#7

7. Mysora Castor Oil Repellent

• Weight: 2.5 lb
• Volume: 1 liters
• Material Features: Castor Oil

Best for: Plant-based garden treatment.

Why it ranks #7: Its 1-liter outdoor formula names gophers, but the listing supplies less application and coverage detail than higher-ranked repellents.

Mysora uses 100% pure, plant-derived castor oil in a 1-liter outdoor formula, and its listing specifically names gophers alongside moles and voles. That makes it a compact liquid option for buyers looking to treat lawns or gardens with a castor-oil repellent.

The product description says its castor oil influences pest sensory perception and is formulated to discourage burrowing animals from settling in lawns and gardens. Its 1-liter volume gives buyers a smaller quantity than gallon-size options, which can suit more limited treatment needs. The listing also describes the oil as biodegradable and plant-derived. Supplied details do not provide a mixing ratio or specific application equipment, so buyers should follow the product directions rather than assume a spray method.

Skip it if you want stated square-foot coverage and hose-sprayer directions; Baar MolEvict specifies coverage and a sprayer mixture.

Consider this for outdoor gopher, mole, or vole concerns when a 1-liter, plant-derived castor oil formula suits your needs. Its listing supports lawn and garden use, but provides less application detail than some alternatives.

#8

8. Natural Elements USP Castor Oil

• Form: Oil
• Volume: 1 gallons
• Material Features: Natural

Best for: USP-grade castor oil buyers.

Why it ranks #8: This one-gallon USP-grade oil is a general-purpose product, not a listed gopher repellent, so it requires more interpretation for this use.

Natural Elements specifies USP-grade, cold-pressed castor oil extracted without hexane, giving this gallon product a clearly defined purity profile. The supplied uses focus on personal care and DIY projects, so it suits buyers seeking castor oil itself rather than a labeled gopher-control treatment.

The one-gallon volume gives buyers a large supply, and the listing describes the oil as odorless and fragrance-free without artificial additives, fragrances, or dyes. It also specifies external use only and says it is not for human consumption. Hair, skin, lash, brow, nail, massage, and DIY uses are listed; no gopher-repellent application directions are supplied. For this roundup, its relevance is as pure castor oil, not a product with stated pest-control instructions or coverage.

Skip it if you want a labeled outdoor repellent that names gophers; Natural Elements Mole and Vole Repellent is listed for gopher eviction.

This suits buyers seeking a gallon of USP-grade oil for the listed external-care or DIY uses. For gopher treatment, its boundary is important: the supplied product details do not establish lawn application directions or pest coverage.

#9

9. US+ Castor Oil

• Form: Liquid
• Volume: 128 fluid oz
• Material Features: Natural, Unprocessed, Cold-Pressed, High-Purity

Best for: Pure oil for DIY users.

Why it ranks #9: The gallon-size, cold-pressed oil is marketed for personal care rather than gopher control and provides no pest-treatment directions.

USP-grade, cold-pressed castor oil is the defining feature of this US+ gallon, with hexane-free processing and no preservatives, fragrances, or fillers listed. The product is presented for personal-care uses, so it suits buyers seeking a large quantity of pure oil rather than a labeled gopher repellent.

The 128-fluid-ounce volume gives frequent users a substantial supply, while the cold-pressed, unrefined formula is specified as fragrance-free and hexane-free. Its stated uses center on hair, scalp, skin, lashes, brows, and DIY applications, not lawn pest treatment. For a gopher-control roundup, that distinction matters: this is a base oil for buyers selecting castor oil itself, and the supplied information does not give yard application directions or a pest-repellent claim.

Skip it if you need a labeled yard repellent with gopher directions; Natural Elements Mole and Vole Repellent lists gophers as targets.

This fits buyers who specifically want USP-grade castor oil in a gallon format and will use it for the listed personal-care or DIY purposes. It is not the clear choice when you need product-specific lawn treatment instructions.

#10

10. Zatural Castor Oil

• Form: Oil
• Weight: 2 lb
• Volume: 950 ml
• Material Features: Plant-Based

Best for: Compact pure-oil supply.

Why it ranks #10: This 32-ounce general-purpose oil is described for personal care, not outdoor gopher treatment, making it the least direct match.

Zatural’s 32-ounce castor oil is cold-pressed from Ricinus communis seeds and packaged in a food-grade bottle with a screw cap for pouring and storage. Its listed features emphasize a single-ingredient oil, rather than a gopher-specific repellent or lawn treatment.

The product is described as hexane-free and made without chemical solvents, additives, preservatives, fillers, or bleaching agents. Those specifications identify it as a straightforward castor oil supply, while its 32-ounce container is smaller than gallon formats and has a screw cap intended to support pouring and longer-term storage. The supplied recommended use is hair growth, and no lawn application directions, gopher claim, or coverage figure are provided. Buyers should distinguish pure oil from a labeled outdoor repellent.

Skip it if you need a labeled castor-oil product for gophers; Nature’s MACE Mole & Vole Mace lists gophers among its target pests.

This fits buyers seeking a compact bottle of pure castor oil with specified processing and storage features. For gopher control, the key limitation is that the supplied listing does not provide pest-repellent claims or outdoor application instructions.
