Hey everyone,
I’ve been seeing a ton of people online recommending boiling water as a quick DIY way to wipe out an ant nest. Some swear it works instantly, others say it barely dents the colony.
I’m dealing with a couple of stubborn mounds in my backyard and I’m tempted to try it, but I’m wondering:
• Does it actually reach deep enough to do anything meaningful?
• Is it dangerous for the soil or plants nearby?
• And is it even worth the trouble compared to baits or other treatments?
Would love to hear from anyone who’s tried it — success stories, failures, or cautionary tales welcome.
Boiling water works… kind of. The problem is that ant nests can go really deep. You’re only hitting the shallow chambers.
Be careful if you’re doing it near grass or flowers. I poured some near my tomato bed and the soil stayed weirdly dry for a while afterward.
I tried it once. It definitely killed the ants near the top of the mound, but the colony rebuilt in like two days.
Most colonies have multiple escape tunnels. Even if you flood one, the queen might be chilling in a chamber far below. That’s why baits usually win.
@YardTinker Personally I switched to gel bait after trying boiling water. Took a few days but the results were way better and didn’t involve hauling a pot across the yard.
I’ve used boiling water on tiny sugar-ant nests and it worked okay. Anything bigger? Forget it. They scatter and rebuild.
Also depends on the soil. Sandy soil drains too fast, so the water just disappears before doing real damage.
@CinderBlockJake Same! I scorched a patch of lawn by accident. It came back eventually but looked rough for weeks.
It’s satisfying in the moment, but not a long-term fix. Think of it like swatting, not solving the source.
If you do try it, wear shoes and stand back. The steam hit my leg once and I learned my lesson fast.
