The Problem We Couldn't Ignore
When the power goes out for days or weeks, people don't think about just staying warm and fed. They think about water. Clean water. And everything that comes with storing water outdoors in summer heat — standing pools, mosquitoes, the mosquito-borne illnesses that follow.
That's how we started. Not with a grand vision. Not with "let's build a preparedness company." We started with a single, desperate question: How do you keep water storage sanitary when the grid fails?
Supplies Are Limited Started With a Single Question
Ask enough people what they'd do if the power went out for a week, and you'll hear some wild answers. But ask them what they'd do if they had to store drinking water for months, and everything shifts to practical. That's where we were in 2022 — practically terrified.
A grid-down scenario means running water stops almost immediately. Within 48 hours, your stored water becomes a liability if you can't keep it clean. You start thinking about mosquitoes, algae, bacteria. The infrastructure most of us take for granted dissolves into a single, urgent problem: How do we keep standing water safe?
Enter Mosquito Dunks
We researched everything — filters, boiling, chemical treatments, UV purification. And then we found Mosquito Dunks.
Mosquito Dunks are small briquettes containing Bacillus thuringiensis israelensis (BTI), a naturally occurring bacterium that kills mosquito larvae without harming humans, pets, fish, or other wildlife. They've been used by professionals since the 1990s, EPA-approved and battle-tested by homeowners managing everything from rain barrels to livestock water troughs.
For us, they solved a critical problem: Keep stored water mosquito-free for 30 days with a single drop-in treatment. No chemicals you're afraid of. No equipment to maintain. No ongoing maintenance. Just biology working the way it has for millennia.
Why This Matters for Supplies Are Limited
Most prepper content starts with fear. Zombie apocalypses, government collapse, end times. We're not interested in that.
Mosquito Dunks represent the opposite philosophy. They're a solution to a real, practical problem. They work with nature instead of against it. They've been tested by thousands of people solving actual problems, not hypothetical ones. And they cost $27 for a 20-pack that handles most reasonable water storage scenarios.
That's what Supplies Are Limited is about: Soft survivalism — practical, accessible, evidence-based preparedness for the real risks you actually face.
Why We Still Recommend Mosquito Dunks
- Biological control: Uses naturally occurring bacteria. No synthetic chemicals.
- Proven safety: EPA-approved, used by professionals and homeowners for 30+ years.
- Easy to use: Drop one briquette in 100 sq ft of standing water. That's it.
- Long-lasting: Each briquette treats for 30 days, then biodegrades harmlessly.
- Tested: We use it ourselves. We know what we're recommending.
