The hack and squirt method is a targeted approach for controlling invasive trees by injecting herbicide directly into the bark. This technique minimizes damage to surrounding vegetation while ensuring the internal destruction of the tree. It is widely used in forestry, pasture management, and restoration zones. Choosing the right herbicide for hack and squirt depends on the tree species, herbicide formulation, and site sensitivity. Herbicides should be systemic and designed for deep root control. Proper application improves effectiveness while reducing environmental impact.This guide features the 10 best herbicides suitable for hack and squirt. Top 10 Herbicides For Hack And Squirt 1. Arsenal Herbicide Arsenal Herbicide contains imazapyr, ideal for systemic control of woody vegetation. Once injected into the cambium, it travels throughout the tree to kill from root to crown. It provides long-term control with minimal re-treatment. Used often in forestry and conservation areas, Arsenal is effective during the active growth period. It's rainfast and requires fewer applications than contact herbicides. Users report high satisfaction with its thorough performance. Apply cautiously near desirable plants due to its non-selective nature. Wear protective clothing and follow label guidelines. Arsenal is ideal for professionals and land managers needing lasting results. 2. Garlon 4 Ultra Garlon 4 Ultra uses triclopyr in an oil-soluble formulation for deep bark penetration. It spreads through the vascular system and disrupts plant growth at the cellular level. It's effective against broadleaf and woody plants. Best applied in spring or early fall, this herbicide is selective, sparing grasses and some groundcovers. It's popular in rights-of-way, pastures, and conservation work. The product is efficient even in small-volume applications. Combine with oil for optimal performance in hack and squirt. Use only during appropriate temperature and moisture conditions. Garlon 4 Ultra is reliable for tough vegetation management. 3. Pathfinder II Pathfinder II is a ready-to-use triclopyr solution that simplifies fieldwork. Its oil-based formula penetrates bark quickly and spreads through the tree's interior. This makes it ideal for remote or large-area work. It's particularly effective for basal bark and hack and squirt applications. Pathfinder II is commonly used in utility and public land maintenance. Application is straightforward with minimal mixing required. Since it's pre-mixed, user error is minimized. Apply directly into cuts made evenly around the trunk. Pathfinder II is trusted for its convenience and results. 4. Crossbow Herbicide Crossbow Herbicide contains triclopyr and 2,4-D for broad-spectrum tree and brush control. It's powerful against stubborn species like black locust and elm. The dual ingredients provide multi-pathway plant kill. Commonly used in agricultural and roadside settings, Crossbow allows for tree control without harming grasses. It performs best when sap flow is downward, such as in fall. Reapplications may be needed for large trees. Use proper PPE during mixing and application. Avoid water bodies as 2,4-D can migrate. Crossbow is a workhorse herbicide for large-scale vegetation control. 5. Remedy Ultra Remedy Ultra offers triclopyr in a highly effective formula for hack and squirt. It's selective to broadleaf plants, leaving grasses unharmed. This is excellent for pasturelands and wildlife habitat restoration. It's often mixed with oil to increase bark absorption. Application during growing seasons ensures maximum effectiveness. Its residual control is appreciated by professionals and homeowners alike. Remedy Ultra is easy to store and mix. Be cautious near ornamentals. It's a go-to for ranchers managing tree encroachment. 6. Polaris Herbicide Polaris uses imazapyr to target tree species from the inside out. It's systemic and offers prolonged suppression of regrowth. It is effective in wildlands, utility corridors, and pastures. Polaris has soil activity and prevents seedling emergence. Avoid using it near sensitive plants or water. When applied correctly, results can be seen within weeks. Use in combination with basal oils for improved uptake. Apply when trees are actively growing. Polaris is best for stubborn and invasive hardwoods. 7. Tordon RTU Tordon RTU is a ready-to-use herbicide that contains picloram. It's applied directly to tree cuts, making it ideal for quick hack and squirt treatments. The purple dye helps with visual tracking. It's commonly used in rangelands and utility sites. This herbicide is rainfast and provides long-term suppression. Tordon RTU is effective on over 20 species. Avoid application near water due to runoff risk. Always follow EPA guidelines. Tordon RTU is convenient and powerful for individual tree treatment. 8. Milestone Herbicide Milestone contains aminopyralid and is effective on broadleaf weeds and small trees. Though not typically used alone for hack and squirt, it boosts other herbicides' performance. It's commonly tank-mixed with triclopyr. This product is rainfast and offers long-term suppression. Milestone is safe on grasses, making it ideal for pastures. Use it strategically to enhance control. Follow mixing guidelines strictly. Avoid drift and application near vegetables. Milestone supports integrated vegetation management plans. 9. Alligare Triclopyr 4 Alligare Triclopyr 4 is a budget-friendly option with the same efficacy as premium brands. It's widely used in hack and squirt due to its high concentration. Effective on hardwoods, it delivers systemic control. It is ideal for range, forestry, and industrial sites. Mix with oil carriers for better penetration. Apply during the growing season for optimal results. Wear gloves and goggles when mixing. Avoid use on windy days. Alligare is a strong value performer. 10. Vastlan Herbicide Vastlan is an aquatic-safe triclopyr herbicide suited for wetland tree control. It has lower volatility and is ideal for use near sensitive areas. It's less aggressive but reliable when used correctly. Its water-based formula allows easy application in damp sites. Vastlan is selective and won't damage grasses. It's commonly used by park managers and conservation teams. Apply only during recommended temperature windows. Always check environmental guidelines. Vastlan is a smart choice for sensitive environments. 7 Buyer's Tips for Hack and Squirt Herbicides Use systemic herbicides: To ensure complete kill from root to tip. Choose oil-based products: For better bark penetration and absorption. Look for ready-to-use formulas: To reduce mixing errors and save time. Mind seasonal timing: Best results occur in spring or fall. Use dye indicators: Helps ensure full tree treatment coverage. Consider environmental impact: Especially near wetlands or crops. Check compatibility: Some work better with basal oil or mix partners. 7 FAQs About Hack and Squirt Herbicides 1. What is hack and squirt? Hack and squirt is a method of cutting small wounds into a tree and injecting herbicide. It targets trees individually for precise control. It's commonly used in forestry and land restoration. 2. When should I apply hack and squirt herbicides? Best application times are spring and fall. This is when trees are actively transporting sap. Proper timing ensures better herbicide uptake. 3. Do I need to dilute the herbicide? Some products come ready-to-use. Others must be mixed with a carrier oil or water. Always follow the label instructions. 4. Can I use any herbicide for hack and squirt? No, only systemic herbicides designed for internal transport should be used. Contact herbicides are ineffective in this method. Check product labels for compatibility. 5. Are these herbicides safe for animals? Most require pets and livestock to be kept away during application. After drying, some are safe.
