What Customers Are Saying

Customers overwhelmingly praise this mosquito control system for dramatically reducing mosquito populations after consistent use over several weeks, with many reporting outdoor spaces becoming noticeably more enjoyable. The chemical-free approach is widely appreciated as safe for pets, children, and the environment. Reviewers consistently highlight the ease of setup and simple refill process requiring no tools. The compact, battery-free design is valued for portability and low maintenance. A few note that late-season deployment or unusual weather may delay visible results, and monthly water top-ups are required, though most consider these minor trade-offs for sustained mosquito relief.

Definitely works!

[This review was collected as part of a promotion.] These refills are so easy to use! Just put the tablets in the water and place the band on! It’s that easy. You can wear gloves to put on. It does work and has kept down the mosquitoes around my door. I was happy they sent refills and I will buy new ones when I run out. If you have a problem with mosquitoes try this set up!

It absolutely works!

[This review was collected as part of a promotion.] This was very easy to set up! I was very excited to put this near the door where mosquitos are the worst! I love how you just put water in and add the tabs in. One great thing about it is the dial on the top to show which month you added it last! It absolutely does work. I noticed I could sit out where I always sit and not be miserable from the mosquitos. I will absolutely continue to use this and buy refills when I run out of the ones sent. It...

It works! A good solution

Would Recommend

I waited to post a review until we got through the first 9 days as the product promises. It has done the job and my mosquitoes are now under control. The setup could t easier. No mechanical or electrical parts to maintain. It just sits passively in the har and quietly does the job. I’m very pleased and excited that I can once again enjoy my open air deck without being eaten alive by the pests. I know they have their place in the world, but I prefer it not be my address. ;^)

Missing tablets

I just set up my system, but my packet didn't contain any tablets or powder, just the band. I paid more because it included 2 kits/bands. I had to take the tablets from the 2nd packet, making that pack useless 😵‍💫

Covers the backyard well!

I do like this product. It does seem to control the mosquitoes. You do have to keep up on refilling the system but it is worth it!

A bit awkward to set up. Seems to be working somewhat. Still some pests around.

Protect your relatives from diseases, your gardens and the whole house.

The Ortho Home defense Mosquito Kill & Prevent system is the best option to keep mosquitoes away both outside and inside you go and more so in these summer days it can also be used anywhere in the house since it covers 4,300 square feet of coverage. Basically what this product does is attract mosquitoes to contaminate them and when they have contact with other places that eliminate the Larva in other breeding grounds thus preventing its spread, it only requires water and changing the refills o...

Refills for Mosquito Defense

[This review was collected as part of a promotion.] These refills are easy to swap out with the old ones. They work great and I’m thrilled with the way my mosquito population has been decimated. It takes a minute for it to start working but it works well so I have no complaints. They’re small and easy to dispose of. Very impressed with the whole system.

Great for summer

[This review was collected as part of a promotion.] Works great. Takes a while for the mosquitos to disappear but I’d recommend putting it out early in the season before you’re outside a lot just to get a jump start. The refills are easy to use and I’ve seen a huge drop in the mosquitos around our front porch area. Now I can sit on my porch and enjoy a book with no little biting menaces. Love it.

Need to be patient but it lasts a while

[This review was collected as part of a promotion.] I’m very glad this came with the refill. This was easy to install and the instructions were very straightforward. I’ve had it in for 2-3 weeks and believe it’s still good. In terms of effectiveness it seems to have reduced the mosquitos a little but I’m waiting for a more drastic drop.

Have to be patient but works decently well

[This review was collected as part of a promotion.] This product was pretty easy to set up, I had it set up for 2-3 weeks roughly now and although I see less mosquitos I’m still dealing with a lot so I’m not sure it’s working that great yet. It could possibly need a little more time. Great packaging and very portable. I do appreciate that it came with a refill.

Great Option

[This review was collected as part of a promotion.] I received the product for free in exchange for my review. I love that it came with refills kits option so i don't have to buy new container every time when the bands expire in one month

Excited to play outside without mosquitoes

[This review was collected as part of a promotion.] I received the product for free in exchange for my review. It's lot of rain as well as sunny day in my area so mosquitoes have been an issue for us, especially for my toddler who loves to play outside. I took off one star since this requires lots of steps to set up. But it's also good that they have a month system so we can keep track of when we need to change the filter. One can last for 1 month which is a good thing.

Easy to replace

[This review was collected as part of a promotion.] These replacements are easy to install and great to have on hand when needed to change out the old refill. This includes two packs of refill. They can be found at any of my local grocery stores and are individually packed and easy stored.
