What Those Black Spots in Your Crawl Space Actually Are
Introduction
Camel Cricket Droppings vs. Mold
DON'T LET SCARE TACTICS COST YOU THOUSANDS
I just wrapped up an inspection in Lebanon, Tennessee. The homeowner called me because another company told her the black spots on her floor joists were black mold. They tried to scare her into a forty-thousand-dollar job.
Here's the problem. It wasn't mold. It was camel cricket droppings.
Now, she still needs encapsulation work. The conditions that attract camel crickets are the same conditions that cause bigger problems down the road. But she doesn't have toxic black mold eating away at her house. She has bugs living in a damp crawl space.
That's a big difference. And it's the kind of lie that makes people distrust this entire industry.
What Camel Crickets Are
Camel crickets are basically nature's cave dwellers. They love dark, humid, moist environments. Your crawl space is exactly the kind of place they're looking for.
They feed on microbial growth. Mold, fungus, old leaves, decaying wood - any kind of organic material that's breaking down. If you've got moisture issues and a little bit of fungus growing on your joists, camel crickets will show up and make themselves at home.
They're not dangerous. They don't bite. They're just an insect doing what insects do - finding food and shelter. But their presence tells you something important. If they're thriving down there, your crawl space has the kind of environment that leads to real problems.
How to Tell the Difference
Camel cricket droppings look like small black specks scattered on wood surfaces. They're dark, they're noticeable, and if you don't know what you're looking at, they can seem alarming.
Mold is different. Real mold grows in patches. It spreads across surfaces. It has texture and depth. Black mold specifically has a slimy or fuzzy appearance. It doesn't look like scattered dots.
But here's the thing - most homeowners don't know that. And some companies count on it. They see an opportunity to use fear to close a deal. They point at those black spots, call it toxic mold, and watch you panic.
That's not honest work. That's a sales tactic. And it's why getting a second opinion matters.
Why You Still Need Encapsulation
Even though it's not mold, those cricket droppings are telling you something.
They're a sign that your crawl space is too humid. That there's moisture down there. That conditions are right for fungus to grow, wood to rot, and bigger problems to develop over time.
Camel crickets don't show up in dry, well-sealed crawl spaces. They show up where the environment supports them. So when I see their droppings during an inspection, I know the homeowner needs encapsulation work. Not because of the crickets themselves, but because of what their presence reveals.
The droppings aren't the problem. They're the warning sign.
How Encapsulation Solves the Problem
When we encapsulate a crawl space, we're changing the entire environment.
We make it drier. Camel crickets hate that. We remove the fungus and mold they feed on. We seal up the cracks, vents, and gaps they're using to get inside.
You're not killing the crickets. You're just taking away everything they need to survive. No food. No moisture. No way in. They leave on their own because there's nothing left for them down there.
That's how you solve the problem the right way. Not by scaring someone with fake mold claims. By fixing the conditions that caused the issue in the first place.
Red Flags to Watch For
If a company is trying to scare you, that's a problem.
Watch out for anyone who throws around terms like "toxic black mold" without showing you proof. Be cautious of companies that rush you into a decision or quote you a massive number before explaining what you're actually dealing with.
A good crawl space professional will show you what's going on. They'll take photos. They'll explain the difference between mold and insect droppings. They'll walk you through what needs to be done and why.
If someone won't slow down and answer your questions, that's your sign to get a second opinion. You're spending serious money on this work. You deserve to know exactly what you're paying for.
