Stem light trap

We live in the mountains. I was noticing a gnat every so often. then I saw this product I thought I would give it a try. I had no idea how many gnats/tiny flying critters I had inside. I am so grateful I found this. It is a little pricey but worth it.

Bugs be gone!

I absolutely 💯 ♥️ these. i started out buying only one due to a Walmart cash back that was practically a freebie. bugs, 🪰 gnats, no see 'ems are attracted to light as well as human breathing. no toxic chemicals, no scent, just a simple plastic card with super sticky, non-scented clear stuff. you simply plug 🔌 them in, remove paper backing on BOTH sides, slide it in, and it glows a gentle blue light (doubles as a night light) and the critters head right on to it where they meet their final destination! uses practically no electricity, doesn't make any noise, it just provides a safe and effective way to solve the problem of getting bitten. once the card is full of stuck on bugs, you simply pull it out and replace it with a new card. i keep one in my bedroom, and it works like a charm.

Iam here to tell you these things really work!! I have the plug-ins that are blue. These are the refills for them. I use them year round. This winter I could not believe how many gnats I were stuck on that thing. It was covered. You would think they would die out in the winter time. No...we are insect infested this day and age. I must just notice it more. But I can't stand little bugs flying around while I am cooking or eating. Go get some Stem units and refills!!
