Amazing stuff!
This stuff is easy to use. It literally does not smell at all. I was pleasantly surprised by that. It’s late spring and i started seeing tiny beetles in my kitchen bathroom and one of the bedrooms. Started out i’d see 2 or 3 a day. A few days later i was easily killing at least 15 or 20 of the little suckers everyday. Used this around the windows and doors. I sprayed all of the baseboards in the house as well. The gallon jug can cover a lot. I sprayed once, and i have not seen a bug since. It’s like they packed up and left. Not one single bug remains. I am sold on this stuff. Worked perfectly!

The best, best, BEST product ever!
This is truly the best product I have ever used, and I will absolutely be buying it again. First of all, it works on ALL types of insects. I’ve seen it take care of spiders, roaches (even the small ones), and even worm-like bugs. No matter what kind of creepy crawler it was, they’re gone. In the beginning, I would see a lot of dead bugs, but after that, nothing. And if I ever find anything now, it’s already dead. I have not seen a single live bug in my home since using this. I recently moved into an older house, and from day one there were so many bugs, especially roaches. I tried different methods before, but nothing fully worked. Spiders were especially hard to get rid of. After applying this product along all the baseboards, the upper corners between the walls and ceiling, around exterior doors, and even outside around the windows, everything completely changed. It’s also extremely easy to use. The built-in handle makes the application so simple and convenient. No complicated setup, no mess, just spray and you’re done. Another huge plus: it has absolutely no smell. None at all. And it does NOT leave any residue behind, so there’s nothing to clean afterward. That was very important to me. The bottle is large and lasts a long time. I personally reapply it every 2–3 months (not daily), and I still have plenty left. Most importantly, it gives me so much peace of mind. I really don’t like insects at all, and knowing my home is protected makes such a difference. Highly, highly recommend!

The dreaded 2026 Ant War is officially over!
Worked like a charm, we had a small black Ant kitchen invasion, I had originally put down several liquid bait traps of different makes, and oddly enough, they were completely ignored. I've used highly rated liquid bait before, and typically they'd make a bee-line right to them, not this time, not after a week. I usually ignore spray but gave in because I wanted the kitchen back. I removed everything, sprayed under the cabinets, sinks, cracks in the wall, pipes, behind the electrical outlets (turn off the circuits first!) - basically everywhere. I also sprayed outside, doors, windows, and created a perimeter. Long story short, well into the next day, not an Ant in sight. I might add, it dries VERY quickly, leaves no residue and the battery operated sprayer has a nice, even spray which includes different settings for indoor and out. A great product and a week later still no signs of the buggers. 10/10

Spray can was worthess, but jug with wand worked well
I purchased both a spray can and a jug with comfort wand at same time. I have a lot of spiders in my basement, and I thought I'd use the can to spray the staircase to basement and some of the basement rafters. I'd have been happy if the can killed the spiders in the stairwell, and kept them from coming back to stairs. I am constantly vacuuming up spiders that inhabit my stairs to basement. So I started spraying from a few inches away a common house spider right after opening door to stairs to basement. Nothing. I drenched the spider, it didnt even seem bothered, sprayed it more till it finally slid down the wall. Did it die? No. Walks off as normal, soak it more now on floor... still not dying. So I vacuum up all the webs and spiders on stairs to basement, then coated the walls, ceiling, railing and stairs heading to basement. Check back 24hrs later, spiders are inhabiting the stairwell that I thoroughly sprayed. Spiders-1 Ortho-Max-Spray-0 I have a lot of carpenter ants in wall near kitchen window, and after addition now-unused old chimney also close to kitchen window. The kitchen window has a screen, but I hadn't been able to open it without getting carpenter ants coming in through the window, especially if it rained. After thoroughly spraying the kitchen window screen, sill, frame, and around the window (inside&out) with the comfort wand it actually repels the ants. I leave the window open and in the 2 months since I applied it, I haven't seen any ants come in, nor any ants even near the window. Max w/ Comfort Wand-1 Ants-0 In previous years stink beetles have driven me nuts. They'd get into the house no matter what I did. When I applied this with comfort wand, I sprayed every window sill, every window frame, a box around every window, window screens, every door frame (that leads to outside of house), covered wall areas of front porch, and all the rafters in my basement. In the 2months since applying this, I've had no stink beetles in the house, and haven't seen any even hanging out on window screens. Max w/ Comfort Wand-1 Stink Beetles-0 I still have a lot of spiders in my basement. It might reduce the amount of new spider webs in basement rafters slightly, but they are still there, and they still find there way to the stairwell heading upstairs from basement. Spiders-1 Max w/ comfort wand-0 (Maybe 3/4to1/4, but spiders certainly have the upper hand.) I didn't specifically spray to control lady bugs. However, I haven't seen lady bugs on the house since I sprayed either. Max w/ Comfort wand-1 lady bugs-0

It is working perfectly
We are having a huge issue with boxelder beetles both inside as well as outside of our house. The sprayer was easy to figure out how to use (I couldn't find any instructions, so I had to just wing it). I like that it is ready to use and no mixing needed. I have a huge two-story house and with one large container I was able to cover all that I needed to and fully drench those areas. I even went back the next day and did it again in the heavily infested areas. Lots of dead bugs so I know that it is working. It doesn't seem to leave any residue or staining on my dark house color. I didn't use it inside my home, but it says you could. I was able to get into tight spaces with the wand as well as it was comfortable to use. I will definitely be buying this product again when I need more.

Have used this product before in the Caribbean. No roaches or the like for 5 years so I know it works. Pretty hefty price tag though for shipment to the UK when much lower price on the other side of the pond. But the heart wants what the heart wants…
