When I arrived at my hotel on a recent trip to Toronto, I did my usual bed check, pulling back the duvet and casting a careful eye over the mattress and box spring. Fortunately, I saw no telltale reddish brown spots, so there didn’t seem to be any bed bugs lurking between my sheets. But if there had been, I had a line of defense: a 20-inch carry-on suitcase from ThermalStrike.
The suitcase (also available in a 24-inch size) uses infrared technology to heat its contents to a temperature of 140 degrees — hot enough to kill bed bugs and their eggs. To start the heating process, you must load both sides of the suitcase evenly, stand it up, raise the telescoping handle and plug the bag into the wall. The heating process shuts off automatically once the treatment is over. (The company’s Web site offers an estimate of 2.5 hours for the “fatal temperature” to be reached, but in two different tests my carry-on shut itself off within 45 to 60 minutes.)
The suitcase gets hot to the touch during the process, but not to the point of danger; kids or pets touching the case by accident shouldn’t be harmed. Of course, you’ll want to take out anything that might be damaged by heat, such as cosmetics, sensitive electronics and that chocolate bar you’re bringing home for Mom.
Read on for a few of my favorite and least favorite things about the suitcase.
Bed bug concerns aside, the ThermalStrike is a solid carry-on bag. The materials are sturdy and high-quality (with the possible exception of the telescoping handle, which felt a tad flimsy), and it’s an attractive bag inside and out. A built-in TSA-approved lock allows for a little extra security, and the spinner wheels were an upgrade over the rolling upright I’ve been traveling with for the last decade.
Though I don’t believe I was in any danger from bed bugs on this particular trip, treating my clothes and other belongings with the suitcase gave me a little extra peace of mind.
I’m used to traveling with a soft-sided carry-on, which has a couple of external pockets where I can stow things like my quart-size bag of liquids and gels for easy access at security. The hard-sided ThermalStrike carry-on was less convenient on that front; to get my toiletry bag out, I had to lay the suitcase on its side and unzip the main compartment to get to the “quick-access pocket” inside — not ideal in a crowded security line.
The pivoting wheels occasionally seemed to get a little stuck when I tried to turn the suitcase, both in the airport and on a few uneven sidewalks in Toronto.
To run the heating process in countries outside of North America, you’ll need both an adapter for the plug and a converter with a voltage of at least 300 watts. (See Electricity Overseas for more info on this topic.)
At $349 for the carry-on and $399 for the 24-inch suitcase, the price may be beyond the reach of many travelers.
If you can afford the price tag, the peace of mind may be worth it, especially for an otherwise sturdy bag.
