Sena has some Japanese Beetle traps she’s been thinking about using for some time now. She paid only a dollar a box because they were on sale. She’s hesitant. It’s Spectracide and uses a sex attractant and a floral lure to catch the little scarab beetles in a bag. In fact, the product is called Bag-A-Bug. The box advertises they are an “ideal method” to control Japanese Beetles and protect your yard. They cost about $8 or more a box, depending on where you buy them.
I checked the internet about controlling Japanese Beetles and I was a little surprised to learn that not everyone is in love with the bag method. Some experts say they might attract more bugs to your yard rather than rid your property of them.
The University of Minnesota Extension web article tops the list of those who caution you not to expect a miracle from the bag method. In fact, they frankly state, “While the University of Minnesota is still performing research to understand this pest, one thing we do know is Japanese beetle traps do not reduce beetle feeding.” They baldly state the traps probably won’t benefit your garden. The issue is the chemical lure itself, which might draw even more bugs to your yard. The more bugs you catch, the more stink they squirt. You can end up with thousands more of them because of the trap itself, causing more damage to your plants than if you didn’t use it at all.
What’s the answer? Toss the little buggers in a bucket of soapy water, believe it or not. And while they make holes in leaves which makes your plants look ugly, they usually don’t kill them. Beetles show up in late June and early July and mess with your yard until mid to late August.
Picking off the bugs and the damaged leaves works as good as anything else and rids the areas of the odor which attracts other insects.
What’s The University of Minnesota Extension’s bottom line on beetle traps? Don’t use them. It’s likely they attract more beetles than they catch.
I also checked the Iowa State University Extension web page on Japanese Beetles. The authors say the bugs are the “worst landscape pest in America” but they also are thumbs down on using traps, saying they attract more bugs than they catch. Here’s a funny quote from an ISU Extension article that I originally used but just found out today is not available:
“The only benefit of JB traps is the emotional satisfaction of seeing and smelling hundreds (thousands?) of dead, decaying beetles.”
The Better Homes & Gardens web page has a similar opinion. So, there you have it. During my web search, I was reminded of a neighborhood we visited several years ago where we saw a lot of back yards with these traps. The bugs were everywhere.
So much for the traps. What the heck, they were only a dollar a box.
