What Customers Are Saying
Customers overwhelmingly praise these insect trap refills for their powerful stickiness, effortless replacement, and chemical-free operation. Most highlight the intense adhesive strength that traps gnats and fruit flies effectively, with many reporting visible results within days. Reviewers consistently note the simple, mess-free replacement process requiring no tools and taking seconds. The double-sided design, long-lasting performance of a month or more, and subtle blue nightlight are widely appreciated. Several value the safety for pets and absence of odors. A few report inconsistent bug attraction or wish for thicker adhesive, but these concerns are vastly outweighed by positive feedback.

[This review was collected as part of a promotion.] Did it work? Yes. Did it work better than the stickers I put on my windows that cost a lot less? No. However, it does look nicer and hides the dead bugs which I love.

Good for catching insects
[This review was collected as part of a promotion.] I only used two so far and the second one caught more insects. It’s really convenient since there’s no order and it’s nice having a blue night light in the room. Hoping to catch some mosquitoes that have been flying in my kitchen next! We have dogs so a lot of their pet hair caught as well lol

Does it’s job
[This review was collected as part of a promotion.] The refills for the STEM insect trap are easy to apply and very sticky! They are not flimsy at all, they’re actually really high quality. They also have no smell. I haven’t had any issues with my cats messing with them, as the stickiness is on the back & they can’t get to it.

No more bugs
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I felt like the refill packs were a great value to help keep bugs out of the house. It was easy to set up and had no strong smell. I love the light to help keep those little flying bugs away. I would highly recommend this product

Easy to use!
[This review was collected as part of a promotion.] The Stem flying insect light trap refills are super easy to pop out and discard without getting dirty or making a mess! The new one is easy to install and just slides into the slot with a fresh new sticky mat. These are super effective at catching small flying insects around the house!

Good
[This review was collected as part of a promotion.] It is very quiet, it disassembles very easily, each bar lasts a long time, it has no science, its moe behind, many mistakes, I highly recommend them if you have a lot of insects at home

Easy to replace
[This review was collected as part of a promotion.] These refills are easy to use and replace in the light trap. They are sticky, and once the bugs are on there, they won’t come off until you throw it out

Trap refills!!
[This review was collected as part of a promotion.] These refills are great. No need to rebuy the entire trap. They are an easy install. No smell, great adhesive for the insects to stick. Will last a long time.

Well worth the price
[This review was collected as part of a promotion.] I couldn’t be more pleased with this product, it is the simplest and most effective way to get rid of flying insects in your home. It’s just a little plug in light that attracts the bugs, with a sticky insert that clicks in behind it to trap them. The starter kit and the refills aren’t exactly inexpensive, but like I said , the system is incredibly effective and you don’t have to replace the inserts very often at all, unless you’re just infeste...

A sticky solution
[This review was collected as part of a promotion.] STEM Flying Insect Light Trap Refills are great to have when using the Light Trap. When enough insects get stuck onto the trap, it's time for a refill change. Using disposable gloves is a good idea if you don't want to accidentally touch what you've trapped or get your fingers on the stickiness. It's fairly quick and easy to change the refill out. The stickiness of the refill stays even with insects stuck to it. Several little gnats and suc...

Easy to change inserts.
[This review was collected as part of a promotion.] The inserts are very easy to maintain and change. They are effective somewhat but not fully. I don’t believe they attracted as many fruit flies as I would like.

The refills work really good with the product
[This review was collected as part of a promotion.] I got the stem as part of a deal and a refill and it’s worked really well!!! it comes as a part of the stem ocular and it’s very easy to install. I will get another refill soon!

Easy to replace, mess free, and effective
[This review was collected as part of a promotion.] The refills are really easy to replace and make the light trap convenient to keep using. I like that they’re mess free and you can simply remove the used one and put a fresh one in. They do a great job catching small flying insects and I appreciate not having to use sprays around the house.

Refill pack
[This review was collected as part of a promotion.] This refill pack is so easy to use you just open up one of the refills peel off the paper from both sides and sticky in the bug light. It couldn’t be much easier.

Easy to install flying insect trapper
[This review was collected as part of a promotion.] I have this placed in a small bathroom. There are occasional bugs. I haven’t seen any of the bugs so far. So it’s hard to tell if it works. The design is nice. One really wouldn’t know that this is a flying insect trapper. The installation is no trouble at all.

Keep them on hand
[This review was collected as part of a promotion.] The packaging is excellent. The performance is very good. Have these handy refills makes it easy not to have to rush to the store when your old one is full. This really helps during those high traffic flying insect times. The construction of the refills are very well thought out. Just pull the tab on both side sides and slide it into your light until it clicks. Easy as 123..

Fewer bugs
Not many bugs are seen on the "traps". We do see fewer fruit flies.

Yay… Refills!
[This review was collected as part of a promotion.] Light trap refills to go with my flying insect light trap plug-in kit. These refills can last up to 30 days before replacing them. This is a safe way to get rid of the insects.
