Holes in the Story (AKA: It wasn't me!)
When someone finds a hole in a wool coat or a silk rug, the first thing they say is, "A moth ate my clothes!" I hate to be the bearer of bad news (well, maybe I don't, I am an entomologist), but that’s not entirely true. The adult moths you see fluttering around? They don't even have functional mouthparts. They don’t eat anything at all. The real villains are their "teenagers"—the larvae. Whether you are managing a high-end retail boutique, a museum, or just your own walk-in

Reading the Book (AKA: It’s not lice)
Since we recently talked about springtails , let’s talk about another common pest that is often confused with springtails. They are found in many of the same places and under the same conditions as springtails. If you guessed psocids, you’re right. If you’ve ever been inspecting a food warehouse or a client’s pantry and seen tiny, pale specks scurrying across a pallet of flour or a dusty shelf, you might have encountered these. They often get called booklice, which is one

Best of 2025 (AKA: You folks are weird!*)
So if you follow me, and you obviously do since you are reading this, there was some good stuff last year. Along with everything else I do, I enjoy writing the blog and doing the wine-ing videos. You folks had some definite winners, so let’s take a look back and see what happened last year! Blogs: You folks really like the “ Not My Fault! ” blog talking about when pests are coming from neighbors. I’m with all of you who enjoyed “ We Don’t Talk about Bruno ” where I talked

The Great Migration (AKA: No More Roommates)
It’s officially winter, and while many of us are dreaming of cozy fires and hot cocoa, our six-legged (and occasionally eight-legged or four-legged) friends have the exact same idea. In the pest world, there’s a common misconception that once it gets cold, all the bugs just… disappear. I wish it were that simple! While some go into diapause (essentially insect hibernation), others decide that your heated facility or home is the perfect place to ride out the chill. Here’s the

A Tiny Problem (AKA: It's a small thing)
I had an amazingly good picture sent to me recently for identification and I realized I haven’t talked about these little insects* on the blog yet. There are millions of springtails in the soil. They are tiny so most people will never notice them outside. There are over eight thousand species worldwide wide but most scientists will tell you that is a huge underestimation. It’s just that no one has identified the rest yet. They get the name “springtail” because many species

Dangerous Alliens (AKA: The invasion continues)
I'm in Orlando this week at PestWorld so I'm super excited to see what's new and get to talk to everyone. Which brings up an interesting point. Is there anything new? Aside from a few new invasive insects which aren't necessarily structural pests (spotted lanternfly, spotted lady beetles, etc.) our pests haven't changed much. So here's a quick rundown of some history on our common pests. Starting with one of my favorites: cigarette beetles. These go back to ancient Egyptian
