Nobody wants to spend $1,500 on an exterminator if a $12 can of spray from Home Depot could solve the problem. That instinct makes sense, and it’s exactly where most people start when they discover bed bugs. Hot Bugz understands why. The sticker shock of professional treatment pushes people toward the hardware store aisle and the YouTube rabbit hole first. The trouble is that almost everyone who tries the DIY route ends up calling a professional anyway, usually after weeks of failed attempts, wasted money, lost sleep, and an infestation that’s spread further than it needed to.
The Sprays You Can Buy Don’t Work the Way You Think
Walk into any hardware store in Denver and you’ll find a shelf of products labeled for bed bugs. Most of them contain pyrethroids, a class of insecticide that was effective against bed bugs 20 years ago. It’s not anymore. Research published in the Journal of Economic Entomology has documented pyrethroid resistance in bed bug populations across the United States, with some strains showing resistance levels over 1,000 times the baseline. The bugs you’re spraying in 2026 are genetically different from the ones these products were designed to kill.
What the spray does accomplish is scattering. When bed bugs detect a pyrethroid application, the ones that survive (which is most of them) disperse. They leave the treated zone and move deeper into walls, behind outlet covers, into adjacent rooms, and sometimes into neighboring apartments. You started with bed bugs in your bedroom. Now you have them in your living room too, and they’re tucked into places that are even harder to reach.
Some products marketed as “natural” bed bug killers use essential oils like peppermint, cedar, or tea tree oil as active ingredients. These have not been shown to kill bed bugs in any peer-reviewed research. They may temporarily repel bugs from a treated surface, which again just pushes them somewhere else.
Bug Bombs Are the Worst Option Available
Foggers, commonly called bug bombs, are the single most counterproductive thing you can do for a bed bug problem. The EPA has specifically warned against using foggers for bed bugs, and the reasons are straightforward.
A fogger releases insecticide into the air of a room, where it settles on exposed surfaces. Bed bugs don’t live on exposed surfaces. They live inside mattress seams, behind headboards, inside box spring folds, within wall voids, and in furniture joints. The fog doesn’t penetrate these harborage areas. The bugs that are hidden, which is nearly all of them, survive untouched.
What the fog does do is coat your living surfaces with pesticide residue. Your countertops, your pillows, your kids’ toys, your pets’ bedding. You’ve added a chemical exposure risk to your household without meaningfully affecting the bug population. And just like targeted sprays, the irritant effect of the fogger drives surviving bugs to scatter and spread.
Hot Bugz regularly treats homes where the client used one or more foggers before calling. In those cases, the infestation has almost always expanded beyond the original room, and the home requires more extensive treatment than it would have if the foggers had never been deployed.
Diatomaceous Earth: Helpful but Not a Solution
Diatomaceous earth (DE) is the one DIY product that actually does kill bed bugs on contact. It works by damaging the bug’s exoskeleton, causing it to dehydrate. It’s non-toxic to humans and pets, and it’s cheap. If you’ve been researching bed bug treatments online, you’ve probably seen it recommended in every forum and comment section.
The problem is application and expectation. DE only works when a bug walks through it. You can dust it into cracks and crevices, behind outlet plates, and along baseboards, and it will kill some bugs that cross those paths. But bed bugs that are living inside your mattress, inside your box spring, or deep in a wall void may never encounter the dust. DE also takes time. A bug that walks through DE might not die for several days, during which it continues to feed and, if it’s a female, lay eggs.
People who rely on DE alone often see a reduction in visible bugs but never achieve full elimination. The population drops, they think it’s working, and then it rebounds a few weeks later because the eggs kept hatching and the bugs in unreachable spots kept breeding. Months go by. They’re still applying powder, still getting bitten, still not sleeping well.
DE can be a useful supplementary tool alongside professional treatment, but on its own, it doesn’t resolve an infestation.
Throwing Away Your Mattress Doesn’t Help Either
This is one of the most expensive mistakes people make. You see bugs on your mattress, so you drag it to the curb and buy a new one. Two weeks later, you’re getting bitten on the new mattress.
The bed bugs weren’t only in your mattress. They were also in your box spring, your headboard, your baseboards, your nightstand, and possibly your carpet edges. Removing the mattress removes one piece of the habitat. The remaining population migrates to the new mattress within days. You’ve spent $800 or more on a new mattress and changed nothing about the infestation.
A professionally treated mattress is perfectly safe to continue sleeping on. There’s no health reason to replace it, and the money you’d spend on a new one is better put toward a treatment that actually addresses the whole room.
The Real Cost of the DIY Approach
People try DIY treatments to save money. But add up what a typical DIY attempt actually costs: two or three cans of spray ($10 to $20 each), a fogger ($15 to $25), diatomaceous earth ($10 to $15), mattress encasements ($30 to $80), a new mattress if you threw the old one out ($300 to $1,000), and weeks of lost sleep that affects your work performance and mental health. The total lands somewhere between $100 and $1,200, and the bugs are still there.
Meanwhile, the infestation that might have been contained to one bedroom when you first discovered it has now spread to multiple rooms. When you do finally call a professional, the treatment scope is larger, and if you’re going the chemical route with another company, you’re looking at multiple visits instead of one.
What Hot Bugz Sees After Failed DIY Attempts
The clients who call Hot Bugz after trying DIY treatments for weeks or months aren’t doing anything wrong. They’re working with the information available to them, and the products on store shelves are marketed as if they work. The disconnect is between what the packaging promises and what the science says about modern bed bug resistance.
Heat treatment resolves what DIY methods can’t because it doesn’t depend on a bug walking through a treated zone or ingesting a chemical. The entire space is brought to a lethal temperature. Bugs in the mattress, in the walls, behind the outlet covers, inside the dresser drawers: they all die. Eggs included. One visit, one day, no residue, no scattering.
