Has Its Limits, But Works Pretty Well
by Theresa A. (5 out of 5 stars)
July 9, 2014

I bought this heat pen because I have "skeeter syndrome." I am buying a second one so I can give one to my grandson, who also has it. When we get bites, they swell up almost to the size of a softball. This pen has been great-- it has its limits, but works pretty well. Here's what I've learned over the last couple of summers: You need to have a fresh 9 volt battery after a month or so of heavy use. If it doesn't get warm enough to be uncomfortable after 20 seconds, change the battery. Hold it on until the bite becomes briefly intensely itchy (about 25 seconds) then it'll stop itching right away and be gone the next day. If the bite is somewhere right over a bone, it doesn't seem to work as well, and repeated heating may help. If you wait to treat the bite, the insect proteins will spread out in your skin and be much harder to heat. So: treat your bite right away, change the battery often, and bites on your elbows or scalp will take more than one heating cycle.

It really, really *almost* works
by Lutraphobe (3 out of 5 stars)

Applying heat is a miracle cure for many of us.

However, in the case of the Therapik, there is one nagging issue that caused me to ditch it and just go with the blow-dryer instead:

The plastic ring on the end creates a small amount of space between the heating element and the bite, which is needed, else the heater touches your skin and you get a nasty burn. This ring, or standoff, NEEDS TO BE TALLER. If skin were flat, it wouldn't matter, but skin on a bug bite usually sticks up a little bit, and that change in height can quickly close the distance between the heater and the end of the standoff. No matter how careful I was, I ended up making contact with the heater about 80% of the time. This left me with nasty blisters.

So that's all it needs. They should just double the height of the plastic ring, and then I think it would be PERFECT..

It works!

I really thought this would be something I ended up returning, but I suffer so much from mosquito bites I just had to try it.

In the 70's our Vietnamese friends told us to use hot water on our bites. My husband said when he was a kid his mother got bit all the time and would hold her cigarette close to the bite to stop the itching. 40 years later (I guess I'm a slow learner!) I figured heat was worth a try so I used a blow dryer at first. It worked! But what a pain to use. Then I found the Therapik Mosquito Bite Reliever
. I have used it multiple times in the 2 weeks since purchasing it and it has worked every single time! Now I can put away all the anti-itch stuff I keep on my desk.

Note: Be careful when using it on swollen areas as you might not be able to tell how hot it is. Just use it a few seconds at a time so you don't burn yourself. :)

It actually works!
by PYL (4 out of 5 stars)

I never expected this to work, but out of desperation I gave it a shot. I'm one of those people that gets HUGE welts when bitten by a mosquito, and to make matters worse, I scar very easily (so itching a lot is out of the question).

At first I thought it wasn't working because I still had large welts. It took a few bites for me to understand that the welts I was getting didn't itch - at all! It is easy enough even my 6 year old uses it when he gets bites.

My two small caveats: I do wish that it is smaller - it is really big and doesn't fit in most of my (admittedly small) purses. Also, you have to keep the pressure on the button. I strongly wish that it would stay on with an auto-off timer because when I have to use it a lot my hand started cramping.

BEST Product we've ever purchased for bug bites!
by Adventures with Amirah (5 out of 5 stars)
August 22, 2016

This is one of the best products I have EVER purchased for our family. My daughter was actually using it this morning after a few of these Florida mosquitos snuck in last night. (She is 7, and uses it by herself with no issues) We initially purchased this for our trip to St. Thomas, where we read that the no-seeums and mosquitos were horrendous. (and omg, they were horrible) This device made all the difference in the world! You simply hold it onto the bite for about 30 seconds, until it is hot on your skin, and that's it. It's as if the concentrated heat completely deactivates the venom from insect bites. My children both have allergic reactions to mosquitos, where each bite swells up to the size of golf balls or sometimes baseballs. Fortunately, if we use this on them within the first 30 min after a bite then they never swell at all and the itching goes away completely. AMAZING!! :)

trades one tissue damage for another. expect resticthing itch
by 🛡️ veracity 🛡️ (3 out of 5 stars)
June 23, 2019

Assuming this operated on the same principle as the more expensive [patented] alternatives here on amazon:
* 2x cost: Bite Helper, vibration + precise skin on metal heating element. asin B01K3BRSGE, (

* ~3x cost: Bite Away, precise skin on metal heating element. asin B073HCGVQV, (


I had this delivered Next Day Prime. I did not choose it based on price, but on swiftness of delivery.
-- replaces the bite tissue damage with heat induced blistering
- imprecise heating element SLOWLY rises to target temperature
- poorly conceived, non-silicone ring spacer
- metal mesh heating element will differently burn than a malfunctioning metal surface
- far too much spring resistance in actuation button
* it seems to chew through alkaline batteries
* hottest output available on first 3 treatments with Raovac 9V (ASIN B00008MOQ5)
+ it does power-on
+ it does heat skin

Load quality alkaline 9Volt batteries. Depressing the 'blue button' begins the slow resistive heating. Red ring illuminates immediately. A warm white glow from the heating mesh appears. Press ring to skin albeit not firmly. Manual recommends a 'treatment' duration of 20 to 30 seconds. Upon fresh battery heat output in that window can be bracing bordering on painful. Hours later near half spehere welts appear.

Because it induced tissue damage I was reluctant to ride out the process having salved the site with topical anaesthetic (Prilocane/Lidocain, RX for burns) which is part of my de facto treatment regimen for bites. Yes, this is overkill; I prefer overkill. OTC 'treatments' are about as effective as placebo. If that works for you then hooray you!

I shall NOT be using this on a child. YMMV

I shall be buying one or both of the patented devices above mentioned.

Therapik is the freaking BOMB
by Geoff Grant (5 out of 5 stars)
September 20, 2018

This thing works. I get eaten alive about once a week during the summer at a friend's house so I've tried everything--Claritin, Benadryl, aloe, peppermint, lavender, alcohol, ice, calamine, baking soda, arnica, hydrocortisone. Nothing worked! I also know how much my bites itch every time. They also swell to cover up to a 5-inch radius. Chiggers, I suppose. I used the Therapik as soon as I realized I'd been attacked and continued to use into the next day. Seriously, folks, cut down itching by at least 2/3 and duration by about the same. These bites are usually so intense, I can't think straight and they last for 3 days! With the Therapik, they were gone in one. But I did use it continuously, every few hours that first day. The thing gets crazy hot and insanely itchy when applied, but 20 seconds versus 2 hours? I'll take it! Therapik is the BOMB!

Had High Hopes, but alas a FAIL!
by LeahBee (1 out of 5 stars)

I was really excited to receive this device which coincidentally arrived the day after I experienced two fresh mosquito bites on my lower leg the night before. I read all the reviews about how it automatically took away the itchiness, but unfortunately that didn't happen for me. Even after multiple applications for multiple days. As a matter of fact, I think it may have made bites itchier and last longer. Usually my mosquito bites stop itching after a day or two of using topical ointments, but after using this device its been about 5 days and I still experience periods of itchiness throughout the day. Frankly I don't think the device heats up high'd do better with applying a hot spoon, which also covers a larger surface. Whenever I used the device it seemed to make my bites really itchy during the application. Guess I'll be going back to using hot spoons and topical ointments to only have to suffer for 1-2 days.

Yes it works reasonably well. Reduces the itchiness of most bites at least temporarily and at least 50 - 100 perceht less itchy on most bites. Some bites will start itching again after an hour or two. So its not a compete panacea (hey that's the first time I've ever used that word appropriately!) but its not just a placebo either!

Underpowered, overzealous
by Level (3 out of 5 stars)
September 17, 2019

The unit seems well made and I have been using it for several months. The primary flaw is the fact it is underpowered. I con only get 4-5 decent treatments where the itch does not return. Every subsequent treatment the unit does not reach the ideal cleansing temperature, and thus the itch returns. Two or even three followup treatments are often the norm.

Perhaps it's the batteries in Colombia or Panama, but I have a friend who owns a mouse shaped unit with a metal plate rather than the coiled wire, and his unit delivers dozens of complete treatments before requiring a battery change. I searched everywhere to find that model without success. If you do find it please send me a ping.
