Does PestVault actually last 4 weeks in a garage?

Mine actually held up fine in my garage until around the 3 week mark, then it dropped off pretty quick after that. I think the scent fading is just how you know it’s done. For the price I just swap them when I can barely smell them anymore.

I had a different experience in my shed, which is a bit drafty and stays warmer than a garage. The pouches actually kept their smell for a solid month in there. I checked them weekly because I was curious, and around week four they started losing that sharp scent. By week five they were pretty much done. What surprised me was that the ones I put in a closed cabinet lasted even longer, maybe five or six weeks before I noticed any drop off. So I think airflow and how enclosed the spot is matters more than just temperature. A garage with a door opening and closing all day probably pulls the scent out faster than a closed cabinet. I don’t swap on a strict schedule anymore. I just go by the smell. If I walk past and can’t catch it, I replace them. That’s been working fine for me.

Mine did the same thing in my garage, and it wasn’t even that warm yet. I got maybe two and a half weeks before I couldn’t pick up the scent at all. I just started marking the date on mine so I stop guessing when to swap them.

Mine actually lasted longer in the garage than I expected, which seems to go against what everyone else is saying. I put one behind some storage bins in late fall and it kept a noticeable smell for close to five weeks. It did get weaker after the first couple weeks but it never fully disappeared the way you’re describing. The only thing I can figure is placement makes a big difference. Mine was tucked in a corner where air barely moves, so maybe the scent just hangs around longer in spots like that. If yours is out in the open or near a drafty door, three weeks might just be what you get. I’d say if the smell is gone, swap it, but I wouldn’t assume they all fade at the same speed.

Mine faded quicker once the humidity picked up.

I used two in my garage last fall and they lasted about three weeks before I stopped noticing them. The one I put in the pantry is a different story though, that one hung in there for close to a month. So I don’t think it’s really about the garage being cooler or warmer, it’s more about how much open air is moving around. My garage has a drafty side door and I’m pretty sure that’s what killed the scent faster. The pantry is closed up so the smell just sits there. If yours is in a spot with any kind of breeze or airflow, I’d just plan on swapping closer to the three week mark instead of waiting for the full four.
