Ranger Bed Bug Heater | 100% to Reach Lethal Temperature | Used by Professionals and Homeowners | Effective Against Moths, Carpet Beetles and Lice.

Not only did this 100% ease my mind after staying at an "exclusive" roach-ridden resort in Key West, but the customer service from the owner himself backs this product inspired me to write this review. I purchased the large size, and as recommended, let my items sit for 8 hours to become egg and roach free (my fear was that the roaches potentially left eggs behind in my belongings, and I did NOT want roaches in my home!). I am happy to say after treating my luggage and all belongings (minus electronics, which I wiped down with clorox wipes) my home is safe and my mind was put at ease immediately upon finding this! Aside from its immediate use, I also use this when purchasing second hand books or clothing to ensure no moths, roaches, bed bugs, whatever! I am SO happy with this product, and recommend to everyone I know! Thank you!

I ordered the ThermalStrike Ranger on 2/2/25, received it on 2/5/25, and upon returning from a trip used it for the first time on 2/19/25. It was easy to set up and use, and the manual is clear and concise. I bought the unit because I was originally concerned about bed bugs (we travel frequently) but it turns out the ThermalStrike unit is also effective against almost all other pests, e.g. carpet beetles, carpet beetle larvae, and carpet beetle eggs. Curious about how to best use the unit, I called ThermalStrike customer service and spoke to Mike, who as it turned out, started the company. To say it was a pleasure speaking with him is an understatement! He took a lot of time explaining the science behind the unit and how/why it works. Long story short, it is effective against almost all pests and their eggs. I cannot say enough positive things about ThermalStrike's customer service and owner Mike Lindsey. He will take extra time to talk with you about your problem, explain what needs to be done, and will do so in a friendly and professional manner; in short, I remain grateful for the assistance. This product is easy to use: read the brief manual, then quick assembly (a couple of minutes), plug and play after that. One plug, no need to plug into two different outlets on different breakers like one of the (well reviewed) competitors. Thermal Strike is much simpler to use in my opinion. According to Mr. Lindsey, the ThermalStrike unit can stretch/contort around a 29 inch suitcase, but I have not tried this yet. Smaller bags (carry-on size luggage, handbags) go in the unit without any difficulties at all. Mike explained to me that various electronics companies have certified that their products are safe up to 140 degrees, so it's OK to put your electronics in the unit - just monitor the unit and when temperature reaches 140 you can be confident that the inside of the laptop got to the magic number of 120 degrees (which kills just about anything in a short period of time), and you can (and should) stop the unit so it doesn't overheat electronics beyond their recommended max of 140 degrees. If you have questions, call customer service and ask for Mike, I'm sure you will have the same courteous and informative discussion that I had. He was generous with his time and even explained why and under what circumstances he founded the company. Very Highly Recommended! So much so, that I bought a second unit for my daughter-in-law's home. You won't be disappointed, and the peace of mind is valuable in and of itself.

I live in a multi-unit high rise building in Ontario, Canada, and I bought the ThermalStrike Ranger in March 2021.In 2017 the person in the unit next to me brought home bed bugs. She told no-one and did nothing about them, and they spread out and infested everyone on the floor. In Ontario landlords are responsible for pest control, and my landlord did his best but without her co-operation, the bed bugs kept coming back. The provincial Public Health doesn't consider bed bugs to be a health hazard, so there was no help from there.I had bought a larger heating unit from another company. It killed bed bugs but it heated up the apartment to 97°F during the heat wave. Since I was baking things non-stop for two weeks, that was extremely stressful.Then I saw the ThermalStrike Ranger.The bed bugs had come in wave after wave from 2017 to 2021. I had run out of belongings and health. I was also stressed from the heat the other bed bug device caused. So I spent some of my remaining savings on the Ranger.I seem to have bad luck with appliances. I had been running the Ranger day and night when I noticed a problem. I emailed ThermalStrike and Mike wrote back. He explained what he thought was going on. We talked back and forth a bit and he demonstrated his superb customer service skills, and made it right. Then another facet of the system (not the heat box) went funky, and Mike made that right too.It's been plain sailing since.Since March I have used the Ranger nearly every day to kill off bed bugs (the bed bug loving neighbour finally moved out), then fleas, and now I'm heating my dry goods to combat weevils. The Ranger is extremely convenient to use, reaches the desired temperatures, and doesn't heat up the apartment. That takes a big load off my mind.I like that the thermometer uses a wired probe. There's no disconnection between the thermometer and the display as can happen with a wireless thermometer. There is a tiny gap in the zippered top to allow the wire through, but nothing has ever crawled out that gap. In the early days I was concerned about that so I filled the gap with Mortite caulk; it wasn't necessary.For hotter days when I have both the A/C and a fan going, I've found it helpful to place the Ranger in a large plastic bag to keep the breeze from the fan from cooling down the unit’s exterior. I don't recommend closing it at the top as water vapor will escape from whatever you're heating, and condense if it can't escape.The Ranger doesn't use too much electricity, unlike the behemoth I was using before (and occasionally still use for larger items), so it doesn't trip the breaker to have both the A/C and the Ranger going at the same time. What a relief!The only improvement I would suggest to Mike is regarding the Velcro straps that hold the pegs inside the corner sleeves. They're a tad too short. I tried stretching the sides of the Ranger to accommodate the length of the pegs, but it didn't work. The pegs are a little too long for the Velcro straps. I think an additional ½” of hook-strap would suffice. To be honest, after several months of using the Ranger, the sides seem to have softened up enough that now I can stretch them up enough to make the hooks catch properly, but for awhile that wasn't the case.All in all, having the Ranger has made my life in a multi-residential building, with other people's bugs, a lot less stressful. Mike gives the Ranger a two-year warranty; he has stood by his product and has provided some of the best customer service I have ever experienced.Thank-you, Mike.
