Consumer's Pest Control Review.
I've been in pest control for 17 years.
I've walked into homes where roaches scatter the second you flip the light switch.
Apartments where people have been spraying for six months straight and the problem just keeps getting worse.
I've seen Raid, Combat, Boric acid, sticky traps, and ultrasonic plugins fail in real homes with real infestations.
These products either scattered the roaches deeper into the walls or killed a few dozen while hundreds more were breeding behind the refrigerator.
Clients asked me what to try before calling a pest control company, so I tested popular options myself.

I Bought and Tested Every One of These. Here's Why PestGuard Is #1:
I did not expect a $29 plug-in device to impress me.
I know what professional-grade treatments cost and why.
But PestGuard kept coming up, clients were sending me videos of roaches within 24 hours.
Infestations that had outlasted my own professional treatments were getting knocked out by people who just followed the instructions and waited.
So I ordered it and plugged one device into an open outlet in each problem room at a rental property I'd professionally treated three times with only partial results.
By Wednesday morning there were dead roaches in every spot I'd targeted.
By the end of the week the infestation was visibly broken.
PestGuard uses silent Dual-Wave ultrasonic technology in a non-toxic, chemical-free plug-in device designed for 24/7 room coverage.
The device is designed for continuous 24/7 operation.
Plug PestGuard into an open outlet and leave it running 24/7 for continuous room coverage.
Use one device in each problem room for broader coverage.
That is how you maintain room coverage beyond isolated problem spots.
PestGuard does not use edible bait or require measured application.
Plug it in, keep the outlet area clear, and leave the device running.
PestGuard is designed to provide continuous coverage throughout the room, without sprays or traps.
What About Just Calling an Exterminator?
I'm an exterminator, and for most residential roach problems, you do not need to call me first.
A professional treatment works, as we use chemicals you cannot buy at a hardware store and we know where to put them.
But one visit rarely does it.
A real infestation usually takes two or three treatments to fully resolve.
Then if you're in an apartment building and a neighbor is infested, the roaches come right back through the walls.
Now you're on a quarterly maintenance plan at $200 to $300 a visit, indefinitely.
Value
A single device runs $29.99 (down from $60).
The 3-Device Bundle bundle comes out to $85.47 total, which is what I'd recommend for a small apartment.
For broader room-by-room coverage, choose the 6- or 9-device option based on your room plan.
For context, a single pest control visit in most markets starts at $150 and rarely resolves the problem in one trip.
You'd spend that on just showing up.
The 90-day money back guarantee means there is no real risk.
If PestGuard is not right for your home, use the 90-day money-back guarantee.
