[This review was collected as part of a promotion.] These refills are affordable considering it has 2 pcs already. They are very easy to install and does not take much time. I bought this together with the starter kit. I am loving these products already even after a few days.

Doesn’t work for me
[This review was collected as part of a promotion.] I don’t know what I’m doing wrong. The light is bright. The sticky mess is pretty stick. Easy to use. Just doesn’t catch any bugs. I’ve had it plugged for days and hasn’t caught nothing. I have another bug catching machine and that ones works.

Easy
[This review was collected as part of a promotion.] These blue liners are double sided which gives double the surface to catch the flying insects. In a couple weeks I got 2 gnats on each side of the liner. Easy to use. Easy to replace. Easy to keep clean.

Easy refill process
[This review was collected as part of a promotion.] Great product. The design is shaped to where you can’t even see what’s inside unless you look directly on the sides. The disposal process is very easy as well. Very durable and holds its value well.

Easy to plug
[This review was collected as part of a promotion.] Disconnect the white base from the plug first pull the blue card out and throw it directly in the trash grab the new refill without touching the glue and put it until it clicks and plug it back Blue cardboard whit a sheet of transparent glue on top. The glue is not toxic,it has no pesticides .1 to 3 months each depending on how many insects there are.

Best sticky traps
[This review was collected as part of a promotion.] These sticky traps are the best! They just snap into place and get to work. You dont have to touch the sticky part at all. They are small enough to not get in the way but big enough to do the job!

Very Sticky To Catch Everything
[This review was collected as part of a promotion.] These refills stick front and back full coverage. Very light weight easy to setup and no smell. Very durable once a bug is on it no coming off. Safe for small children they will not be able to stick finger on it .

So gross but so good
[This review was collected as part of a promotion.] The STEM flying insect light trap is incredible, as are the refill traps to keep it running. The refills are so quick and easy to use, just peel the paper off of both sides and pop it back into the trap. I haven't kept track of how often they need to be replaced, but I do notice that it catches more bugs when it's warm outside. Now I have no more problems with keeping a fruit basket on my counter!

Seems to work
[This review was collected as part of a promotion.] These are sticky and have glue on both sides of the board which is nice. They do seem to catch gnats decently. I've caught a few in the last couple of days.

Great bug trap
[This review was collected as part of a promotion.] I put this in my RV on my last camping trip as bugs are always a problem! It worked so well to attract and trap the bugs that made their way into our RV. It was so easy to set up and use. I will definitely be keeping it on hand for future camping trips. The light also acts as a great night light, but is pretty bright. Refills are affordable and will last a while.

This refill pack will last MONTHS
[This review was collected as part of a promotion.] I love how the refills come in packs of 2. I rarely have to buy new ones. It is very affordable. Putting a new sticker into the light is so easy and takes 5 seconds. It is super sticky and it catches bugs I didn’t even know I had!

We're sorry to hear this, Emmah. We'd expect this to attract and trap pesky flying insects when placed where they are present. As this wasn't your exp... Read More
