Avenger typically starts to work within a few hours and can take up to 36 hours after application for full effectiveness. It performs best on days when temperatures are above 50 degrees Fahrenheit. Keep in mind that areas in full shade may yield varied results. The hotter and sunnier it is, the more effective Avenger becomes.

Avenger only targets the top growth of weeds or grasses, leaving the roots unharmed. As a result, weeds may regrow after treatment. Additionally, Avenger does not prevent the germination of future weeds, meaning that new weeds can sprout again. Therefore, a second application may be necessary. Generally, throughout a growing season, 3 to 4 applications are recommended for complete control.

Avenger is 100% organic and derived from citrus oil. We do not recommend eating it. We recommend keeping off the area until the product has dried.

Note that the Colorado Department of Ag does not permit the use of the word safe when describing weed controls.  Even though Avenger is Generally Recognized As Safe (GRAS) by the FDA, meaning it poses essentially no measurable toxicity to people and pets, it cannot be called safe. 

Avenger is a contact herbicide, meaning it only kills the parts of the plant that it directly touches. Results can be observed within 1 to 36 hours after application. On the other hand, Glyphosate is a translocation (systemic) herbicide, which means it can move throughout the entire plant, even if the applicator did not achieve complete coverage. Results from Glyphosate can be seen between 10 to 14 days after application. coverage. Glyphosate results are seen between 10 to 14 days after the application.

If it rains or if the product is applied incorrectly (for example, on a cold day), we will reapply the product at no additional cost. You will need to wait 2 to 5 days to see if the product has been effective. After that period, please give us a call to discuss the results of the weed control, and we will assess whether another application is necessary.

If the product damages some weeds but leaves a bit of green, we can reapply it; however, we may charge for this application since we initially indicated that two applications might be necessary.

Please note that the Avenger product is not effective on weeds taller than 6 inches. Therefore, we usually do not attempt applications on larger weeds.

Yes, as a non-selective herbicide, Avenger will kill any plant it touches, including grass. However, it might take multiple applications to get complete control over well established grasses. 

Avenger is a post-emergent herbicide, meaning it only kills actively growing weeds. It does not prevent new weed seeds from germinating.

Tough or perennial weeds may require multiple applications. Wait anywhere between 7–14 days before re-treating areas that still have visible weeds.

Avenger Weed Killer targets plant surfaces and does not persist in the environment, so it is considered safer for pollinators compared to synthetic herbicides.
