Query: It's somewhat effective, but there are better options...

I found these traps to work fine for the first 2-3 weeks, but then they stopped catching moths. I don't know if it's because the glue got less sticky as a result of dust, or if the pheromone strength wore off. Another problem with this trap is that because of its shape, the moths will fly into the corners and explore the trap, but they might not necessarily go inside and get stuck on the gluey surface.I also tried the Cupboard Moth Traps and I think the Cupboard traps work better than the Springstar traps. The traps are flat, so the moths get stuck almost immediately. Another advantage is that if you notice a moth flying around, you can grab a trap and try to swat at the moth and get it stuck on the surface--you can't do that with the Springstar trap. The trap still has the problem where it seems to lose its effectiveness after 3-4 weeks, but overall I'm quite happy with it.
