Will Cockroach Spray Kill Bed Bugs?

Will cockroach spray kill bed bugs? Find out if using roach spray is a real solution or just a waste of time when you’re dealing with a bed bug problem.
It’s hard to sleep when you know bed bugs might be crawling around.
You spot bites. You flip your mattress. You start to panic.
And then you look under your sink and spot a can of cockroach spray.
A thought pops up — “Will cockroach spray kill bed bugs?”
There are a lot of questions like this asked when they’re dealing with an itchy, stressful problem like this.
Let’s dive into what works, what doesn’t, and what you can really do to get your home back to normal.
Let’s Talk About Bed Bugs
Before we even talk about sprays, Let’s know what these bugs are;
Bed bugs are:
- They are very tiny
- Flat and reddish-brown.
- They are primarily active at night (they love feeding while you’re asleep).
- They are hard to find because they hide in cracks, mattresses, and behind picture frames.
They don’t carry diseases, but they do leave itchy bites and cause severe stress.
So, Will Cockroach Spray Kill Bed Bugs?
The answer is obvious: it cannot.
Manufacturers make cockroach sprays to kill cockroaches. It might kill a bed bug if you spray it directly, but that’s not enough.
Bed bugs don’t hang out like roaches do. They are hiding and lay eggs in places you can’t see. And they spread fast.
Cockroach spray might help you kill one or two, but it won’t fix the whole problem.
Bed bugs need specific kinds of treatments. Even then, it usually takes more than one try.
So, cockroach spray is not a good way to kill bed bugs. You need something more substantial and more targeted.
What Makes Bed Bugs So Hard to Kill?
They are super and naturally stubborn to kill. Here is why:
- They’re great at hiding. They squeeze into the most minor cracks and only come out when you’re asleep.
- They lay lots of eggs. Even if you kill the adults, new ones can hatch days later.
- They’ve gotten used to some sprays. Over time, bed bugs have built up resistance to specific chemical treatments.
So, just spraying around with cockroach spray won’t work.
It might feel like you’re doing something helpful, but you’re really just wasting time and maybe even making it worse.

What Should Be Done Instead
If you have bed bugs, this isn’t something to ignore. You don’t want it getting out of hand.
Here’s what works better than cockroach spray:
- Wash and dry everything. Use hot water and a hot dryer. Bed bugs can’t survive high heat.
- Vacuum like crazy. Go over your mattress, couch, baseboards — anywhere they might be hiding. Then, toss out the vacuum bag right away.
- Use bed bug sprays, not cockroach ones. Look for ones explicitly labeled for bed bugs.
- Cover your mattress. Use a bed bug-proof cover. That traps any bugs inside and keeps new ones out.
- Call a Pest Control Company. Seriously, this is your best move if things get bad.
When It’s Time to Call the Pros
Sometimes, you do not want to make that call because you feel you can handle it, but you haven’t. You can do everything right, but bugs are still showing up.
If you’re in Canada, there’s a great pest control company in Edmonton that can help: Professional Pest Management. They’ve dealt with this stuff for years and actually know how to solve it.
Getting help isn’t giving up. It’s taking your home back.
Why Cockroach Treatments Are Different
Let’s go back for a second and talk about why Cockroach Treatments don’t work on bed bugs. It comes down to how each pest lives.
- Cockroaches come out in the open. Bed bugs don’t.
- Cockroach sprays are more general. Bed bugs need targeted stuff.
- The chemicals are different. Bed bugs need products that get into where they hide.
So, using cockroach spray is kind of like using a spoon to try and hammer in a nail. It’s just not made for the job.
Why This All Feels So Overwhelming
Let’s be honest. When you’re dealing with bed bugs, it’s not just about the bugs. It messes with your head.
You don’t sleep well. You feel gross. You feel like your home isn’t really yours anymore.
It’s not your fault, and bed bugs don’t mean you’re dirty.
They don’t mean you did something wrong. They’re just pests.
Tough ones, sure, but still just bugs.

What You Can Do Right Now
Here’s a simple plan you can follow today:
- Check your mattress and sheets for little blood stains or black dots. That’s usually a sign.
- Wash your bedsheet and bedding with hot water.
- Vacuum daily around your bed and baseboards.
- Buy a bed bug spray, not cockroach spray. Look at reviews first.
- Use a bed encasement to trap any that are still inside.
- Reach out to a Pest Control Company if things don’t improve in a week or two.
Try following these steps and be free from bed bugs.
Other Pests Bugging You?
If you’re also seeing signs of other pests, like mice or roaches, that’s something to handle, too.
Mice Control is another issue that can affect your home’s cleanliness and safety. If you hear scratching in the walls or see droppings, don’t wait.
Mice carry germs and can chew through wires.
Getting a full check from a pro might help spot other problems early — before they get worse.
