Dichroma 48 Pack Refills for Katchy Indoor Insect Trap and Stem Fan Trap | 4.13" Replacment Glue Boards for Fvoai H3 M3 Insect Trap, Sticky Pads for Dunaga, Catchy, Dovsav, CAGVG Fly Trap Bug Catcher

The Good: Excellent stickiness and adhesion for flying insects, more so than other generic brands on Amazon. Accurate sizing at 4.13" (10.5cm) and verified in the photo above with tape measure. Sturdy, flexible pad gives long-lasting results and makes custom fitting a breeze. A low price of $4.99 for 12 pads makes this endeavor worth it. Very fast shipping time. The Bad: The pads did not fit inside my fly trap in the picture, however no generic pads fit this model exactly, so I had a choice of 3.4" or 4.13" pads for my fly trap. I decided on the 4.13" pads and cut the pad to 4" to fit the trap easily in under 30 secs. You can cut the tab off for a better, more-rounded fit. Overall: This is a recommended purchase to anyone with a fan-powered fly catcher. It's the lowest price on Amazon for 12 tabs that actually get the job done unlike some other competitors. No fuss. No mess. No more bugs.

It works in my STEM

These work great for my katchy original. I see some reviews complaining these don’t fit because of the tab and the cut them off. Please don’t. They are part of the design to allow easy removal. Simply bend the tab upward as I show, before removing the sticky protection tape. It fits perfectly. You can see how well it works for my current gnat infestation in my potted plants due to humidity. I’ve had this katchy for years and it’s a great workhorse.

I have a few different machines and was running low on pads. I noticed the ones that came with the Dunaga were absolutely horrible; bugs could still move around so you had to try to kill them yourself without letting them escape. Fortunately, these pads are sticky and can trap bugs. The downside is that they're about 10% smaller, but thanks to the product description and reviews, I knew that beforehand. Given that they can actually trap the bugs, they're far more useful than larger pads that don't work. If it weren't for the small size, they'd be perfect.

Price is great for the amount provided, comes with a tab to hold onto while peeling it open, just bend the tab up when installing it.

I got these for the brown recluse spiders. I can't spray due to my asthma. It works great even caught a black widow.

Not the right but it cut it to work. Description showed the fly catching machine I have but it was too big so I had to cut the trap pad. Ended up working.

They shipped very fast and the product is as advertised. I am very happy with my order.
