Mammoth Control: Our Field-Tested Take on This All-Natural IPM
Powerhouse
When it comes to Integrated Pest Management (IPM), few products have stirred as much buzz in recent seasons as Mammoth Control. From large-scale commercial facilities to boutique indoor grows, we’ve seen this all-natural preventative show up again and again on spray schedules across the country—and for good reason.
While there are dozens of insecticides and fungicides on the market claiming to be “safe” and “effective,” Mammoth Control is one of the few that consistently delivers in real-world conditions without adding complexity to your protocol—or stress to your plants.
In this post, we’ll break down what Mammoth Control is, how it works best, and what we’ve observed from growers who rely on it.
What Is Mammoth Control?
Mammoth Control is a 100% all-natural, plant-derived preventative insecticide and fungicide developed by the same minds behind Mammoth P. Designed to target both mold and insect pressure, its proprietary blend features active compounds found in thyme oil and corn oil—two ingredients known for their antimicrobial and insecticidal properties.
Unlike conventional chemical sprays, Mammoth Control is FIFRA 25(b) exempt, meaning it’s classified as a minimum-risk pesticide by the EPA. It leaves behind no toxic residue, is safe for lab testing, and won’t disqualify your product from compliance testing in regulated markets.
Where Mammoth Control Excels
We’ve seen this product at work in diverse cultivation environments—from arid outdoor fields in Arizona to tightly controlled indoor grows in Massachusetts. Across the board, its preventative use has been where Mammoth Control shines the most.
- Here’s what growers consistently report:
-
Fewer pest flare-ups during veg
- When used weekly during the vegetative stage, Mammoth Control creates an inhospitable environment for mites, thrips, aphids, and whiteflies before populations can establish.
-
Noticeable reduction in powdery mildew outbreaks
- Especially in greenhouses or humid environments, weekly foliar applications have shown significant results against early signs of powdery mildew and Botrytis.
-
No issues with lab testing or plant quality
- Because it’s made from all-natural oils, Mammoth Control doesn’t show up on testing panels or leave behind residues that affect aroma or smoke quality.
-
Fewer pest flare-ups during veg
Best Practices from the Field
- Use it preventatively—not reactively: Growers who apply Mammoth Control before they see issues tend to see the best results. Once pests or mildew gain a foothold, heavier interventions may be required. Think of this as armor, not ammo.
- Stick to the weekly schedule: Weekly foliar sprays—especially during early veg and transitional periods—help maintain a clean canopy. For foliar use, start with 1 oz per gallon of water and increase to up to 3 oz per gallon for heavier pressure.
- Spray in low light conditions: Apply after lights off or in the late evening if growing outdoors. Like many oil-based products, Mammoth Control can cause leaf burn if applied in high heat or direct sun. Always observe plants after first application.
- Use it as a root drench when needed: Mammoth Control can also be used as a root drench (1 oz per gallon) to suppress fungus gnats and other substrate pests. Several growers we’ve spoken with use this method mid-cycle to keep soil-borne issues at bay.
Honest Review: Where It Fits Best
Mammoth Control isn’t a cure-all—and it’s not trying to be. If you’re facing a full-blown infestation, it may not be the silver bullet you’re looking for. But as a preventative tool in a smart IPM plan, it’s a clear winner.
It’s especially effective in:
- ● Veg and early flower, when plants are most susceptible to pest colonization
● Greenhouse or humid environments, where mold pressure can spike unexpectedly
● Organic or low-input grows, where residue concerns are top of mind
With no re-entry interval, no negative lab testing effects, and broad-spectrum suppression of many of the most common cannabis pests and pathogens, Mammoth Control has become a go-to solution for growers who prioritize clean inputs and plant safety.
Final Verdict
At GrowersHouse, we’ve had countless conversations with cultivators who swear by Mammoth Control as part of their weekly spray routine. It doesn’t knock pests dead on contact—but it stops them from showing up in the first place.
And for most growers, that’s exactly what a good IPM product should do.
