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.

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!

Great product!

[This review was collected as part of a promotion.] Refill kits are easy to use, don’t take up a lot of storage space, work well, and the overall system is easy to maintain. It works for us, especially living in a humid and hot environment. Easy enough to take on the road with us too!

Low maintenance and works!

[This review was collected as part of a promotion.] Living in a warm and wet climate this is a must year round. We use it while camping and hanging outside. While it does have a larger footprint than other methods, it does the job well. It’s effective at trapping pesky bugs and after the initial investment refills are cost effective. It was easy to put together! Would recommend for areas that are big prone.

Easy to set up but not much change with mosquitos

[This review was collected as part of a promotion.] The product is easy to set up. It looks fairly nice but the smell is strong and overwhelming. The fact that there is water in the container that can easily spill makes it difficult to situate it near a sitting area where pets and children can’t reach it. It would probably be an ok product if it wasn’t used around kids and pets and around someone who is not sensitive to its smell. Also, number of mosquitos seemed the same even with the product a...

Esthetically ok but didn’t perform as expected

[This review was collected as part of a promotion.] The product was fairly easy to set up. We first placed it on the ground but quickly realized that with water in it, it will be too easy for our little child or dogs to tip it over. We moved it further away from the sitting area but that, I think, made it less useful because of the distance between the sitting area and where the product was located. Visually, the product is esthetically pleasing. However, the smell is strong and, too me, it make...

Easy-to-use refills for a clever system

[This review was collected as part of a promotion.] Ortho Home Defense Mosquito Kill & Prevent Refill Kits 2-Pack is an easy-to-use replacement for the "bands" that come with the system. You just have to replace the band each month to continue to contaminate mosquito larvae. They are easy to dispose of in the same packaging, and they consistently work for about a month. I think I will have less mosquitos this year with this clever system.

Clever solution to control mosquitos

[This review was collected as part of a promotion.] Ortho Home Defense Mosquito Kill & Prevent Starter is a clever idea. Mosquitos are attached to the water in the container, which mimics an ideal breeding site. The included pesticide contaminates the eggs they lay, and then they spread the contaminate to other breeding sites. The larvae in the container and other breeding sites die, so new mosquitos can't develop. The pesticide "band" lasts for one month, and there is a tracker on top to know w...

Great!

[This review was collected as part of a promotion.] This is a really good product especially for these outdoor times. It is very easy to set up, not heavy at all and I feel it does do a good job. I’ve placed it in the garage since it’s were we like spending time.

Easy to use

[This review was collected as part of a promotion.] I can’t believe how well this Ortho Home Defense kit works. You take those refills in picture one and put them in the container in picture two. It treats over 4000sf. There was no real odor and we were able to tell a difference in the mosquitoes pretty quickly. I’m excited to use this over the summer. The mosquitoes are always so bad and I think this will help. The refill packs do not come with the container in picture two. That’s just what you...

Actually works

[This review was collected as part of a promotion.] When you live in a tropical environment, mosquitoes feel like an inevitability, but this system worked so well in getting rid of them. This system was so easy to use, and it actually worked. I’m excited to have this for the over the summer when it’s hard to hang out in the backyard because of the mosquitoes. It’s easy to move and didn’t have an odor I noticed. I especially like how you don’t batteries to use it. You just set it up and let it do...

Easy and effective

[This review was collected as part of a promotion.] I’ve been using the refills for my mosquito system and they are important to be replaced to keep the results consistent. I can tell it’s working because there are fewer mosquitoes, especially in the afternoons. It’s super easy to swap out the refill. There’s no strong smells. They are worth it.
