What Customers Are Saying

Customers overwhelmingly praise this mosquito control system for its effectiveness in reducing populations within days or weeks, particularly in outdoor living areas. Most report visible declines in mosquito activity, especially during peak seasons, and appreciate how the system prevents larvae from hatching rather than trapping adults. Setup is consistently described as simple and quick, taking just minutes with clear instructions, and monthly refill bands are easy to replace. The starter kit includes two refills, offering good value for seasonal use. A small number report no noticeable change or express concerns about powder handling, but most find it worthwhile for reclaiming outdoor spaces.

Good to have a replacement!

[This review was collected as part of a promotion.] I haven’t used the replacement yet since I’m still using the one that was included in the starter kit however I was happy to get a two pack refill for this item. I put it near our fire pit and it seems to be working well so far. Excited to see how it works through the summertime.

Good for summertime

[This review was collected as part of a promotion.] Nice to have for summer time to keep the mosquitos away. Just need to remember to put it away from children and animals. I put ours at the wood line near our fire pit and it works well.

Refill packs for the Ortho Mosquito control

[This review was collected as part of a promotion.] These are the refilled little packs that go in my Ortho home defense. They sent a 2 pack and each one lasts about a month! I thought that was really generous. They are easy to use and dispose of. Theres no strange scent. I love the fact that this system isnt letting out harmful poison into t he air, so its safe for children and dogs. Really loving sitting outside without the mosquitos trying to pick me up and carry me away!!

Get rid of mosquitos with no harsh spray!

[This review was collected as part of a promotion.] Okay, Ill admit it....I was a little confused at first how this was going to stop mosquitoes. I read all the directions and assembled it together. Boom! It does its own work! The mosquitos are attracted to it then take the poison back and it starts to kill the population! Its not a sprayer like I originally thought! Which is amazing, because you can use around pets and children...and I have both! It took about a week to start noticing result...

Refill pack a bonus!

[This review was collected as part of a promotion.] I got the refill pack a few days days after receiving the original box. Now I have enough refills to last for a few months which is great during mosquito season.

Seems to work!!!

[This review was collected as part of a promotion.] I am using this on my front porch where I normally get bit constantly. It seems to be working. It’s fairly simple to put together and I like that it has the dial to remind you when to change the refill

Works great!

[This review was collected as part of a promotion.] I live in a coastal region with lots of mosquitoes. They are so bad here. Placed the Ortho Home Defense near the front door today and immediately I noticed a reduction in the mosquitoes flying. Checked hours later and saw absolutely no mosquitoes...Great product, definitely works well. Thank you Influenster for sending for review and incentivizing me to write this post.

Good refill band pack of 2

[This review was collected as part of a promotion.] Great refill pack for the mosquito kill and prevent station. Comes with two refill bands in the pack so good for two months! Station should be switched and refilled monthly so I’m glad I also got another refill band pack aside from the two that already came with the station. I recommend these and the station if you don’t have it already. Great addition to the backyard to kill and prevent mosquitoes from your outside area! Dilutes great in the w...

Great to keep your backyard clean of mosquitoes

[This review was collected as part of a promotion.] This is very cool! We as a family always love to enjoy our backyard but hate the fact that in the summer time the mosquitoes go crazy! We have to spray ourselves down with nasty spray to not get bitten like crazy. This was the perfect addition to keeping our backyard free of mosquitoes. It was very easy to assemble and start up. All the instructions are clear. Fill up to the water line and at the refill in how it states and place it outside whe...

Easy to apply

[This review was collected as part of a promotion.] Like that the Ortho Refills kit makes it easy to use and simple application to apply to the bucket. Good performance and gets the mosquitos from multiplying. The duration is set for one month which is good enough to get them out.

Easy set up and good results

[This review was collected as part of a promotion.] Really think that Ortho Home Defense Mosquito Kill and Prevent is a realistic option to help get rid of them pesky mosquitoes. The instructions was simple and easy to set up. It’s durable and don’t need much maintenance except when it’s time to replace the pill and powder which is once a month. I have placed it at back yard which has the most mosquitos. It’s perfect.

Ortho Home Defense Mosquito Kill & Prevent Refill

[This review was collected as part of a promotion.] The Ortho Home Defense mosquito kill refill kits 2 pack is a convenient option for keeping mosquito control going. The effectiveness is noticeable, with fewer mosquitoes after use. It provides good coverage for outdoor areas, and the system stays relatively clean with minimal mess. The value is solid since you get two refills, and I appreciate the focus on safety when used as directed.

Yay for more

[This review was collected as part of a promotion.] These refills last for a month! I think that's pretty cool! I also was super excited to get more refills. The box comes with 2 already so this was a nice bonus! I have 4 months of mosquito defense! Which will last me through the hot Georgia summer

Nice

[This review was collected as part of a promotion.] Alright! This was a pretty neat little kit! I don't know if it is going to work because I won't be able to test it long term before the review is due. However it was really easy to set up! I didn't really like touching all the powder to connect the piece in the middle with the actual defence stuff on it. I am a little worried about feral animals trying to get in it. Idk we will see if it works! Easy to put together!
