Top 4 Best Japanese Beetle Traps (2021 Review)

Japanese beetles are an imported scourge for farmers across the United States. There are over 300 different types of plants they will attack and destroy every year. They are such a problem that researchers went right to work creating lures that would trap them.

Modern traps use a food lure and a sex lure that uses pheromones. The double action of combining both lures into one has proven highly effective at drawing them in from a wide area. Therein lies the problem.

FEATURES
  • Long-lasting and easy to assemble
  • Dual-action attractant
  • Easy to take apart and dispose

The lures work too well. They wind up drawing in more Japanese beetles than normal. Even after accounting for the ones the traps catch and kill, you still wind up with an excessive number of beetles that wouldn’t have been there if not for the traps luring them in.

Traps can be part of your overall strategy to get rid of Japanese beetles, but they can’t be the only part. Here in this article, the first part of a 2-part mini-series, we’ll cover the traps you can use as part of that broad strategy.

Then we recommend that you read our companion piece, part 2 in our mini-series, on How to Get Rid of Japanese Beetles, where we show you how to eradicate them completely.

So, let’s get started.

Top 4 Best Japanese Beetle Traps

What Are Japanese Beetle Traps?

Japanese beetles (Popillia japonica) were accidentally imported into the United States in New Jersey, around 1916. In Japan, natural predators kept them in check and the surrounding oceans prevented them from spreading. In the U.S., neither exists to stop them.

They quickly spread, triggering eradication and quarantine efforts at both the state and federal level – efforts that utterly failed. Therefore, attention was turned to methods of controlling them. Along the way, attractant lures were discovered and used to create traps.

Japanese beetle traps typically consist of yellow vanes in a crisscross shape with the lure fixed in the middle. Adult Japanese beetles are drawn in by the odor of the lure and bang into the yellow vanes. Then they drop down into a catch bag.

The catch bag is normally an hourglass shape, which prevents the beetles from being able to escape. For best results, the trap should be hung from a stand 4-5 feet high.

How Do Japanese Beetle Traps Work?

Japanese beetle traps use a two-part lure to attract the beetles.

The food lure part of the attractant draws in the beetle population that is looking for something to eat. It emits an odor that smells like a damaged flower. This attracts both the male beetles and female beetles.

The other part of the lure, the pheromone part, disrupts their life cycle by attracting adult beetles to the trap instead of each other. It mimics the smell of a female beetle, attracting the males to the trap instead of the females.

Once they fall into the bottom part of the trap, the narrow opening at the top confuses them. They’re unable to figure out how to successfully navigate the small opening directly above them. The sun warms the bag until they die from the heat.

Dead beetles begin to smell bad very quickly. If the odor becomes too strong, it will overpower the attractant and other beetles will stop coming to the trap. Therefore, you need to empty the bag at least once every couple of days.

Are Japanese Beetle Traps Effective?

Absolutely. As noted earlier, though, that’s the problem with them. We’ve discovered that an infestation of Japanese beetles can’t be cured by trapping them. Their numbers are simply too high because there aren’t any natural predators in the United States to keep them in check.

Japanese beetle damage in the United States tops $400 million per year, with no end in sight. The traps for Japanese beetles were developed to combat them.

Researchers at universities around the country are highly motivated to find ways to control the beetle population and unfortunately have confirmed what pest control professionals in the field had discovered – that traps attract beetles from the surrounding area and make the problem worse.

How To Use A Japanese Beetle Trap

Assemble the trap according to the instructions that accompany it then hang it from a rod or hanger. Don’t hang it from a tree! That will only subject the tree to an additional invasion of beetles.

Position the traps a minimum of 30 feet away from the plants and bushes you’re trying to protect. The idea is to draw beetles away from the protected plants rather than toward them.

Are Japanese Beetle Traps Safe Around My Pets And Children?

Yes. In fact, your pets and children are more of a danger to the traps than the other way around. Cats and dogs can rip or bite holes in the bags, letting the beetles escape. Playing children can knock the trap over or tear it or punch holes in it with their toys.

The only hazard to your pets or children is if they physically handle the lure and get the smell all over them. The beetles will then be attracted to them and start swarming around them.

Best Japanese Beetle Traps Reviewed

  • Lasts an entire Japanese beetle season
  • Dual-acting attractant to lure beetles in
  • Easy to assemble and dispose of beetles

The best DIY pest control products will combine powerful lures/chemicals and be easy-to-use. The Bag-a-bug Japanese beetle traps by Spectracide definitely fit these criteria. This product uses a pheromone to draw in male Japanese beetles and a floral lure that triggers the feeding instincts in these pests. 

Once the beetles land on the valve at the top of the bag, they fall inside and become trapped with no way to escape. One bag can cover a 5,000 square foot area and you can simply hang the bag about 30 feet from targeted plants from a post or stake. 

This is great because the bag’s lure will attract the beetles in flight or from the ground below. The dual combination of pheromones and floral lure can attract 3-5 times more Japanese beetles than one lure. 

For best results, empty the bag every 3-5 days to make room for new beetles. Make sure you replace the lure if it is no longer attracting beetles. It will also help to have some replacement bags on hand throughout the season. 

Pros

  • Perfect for the entire summer and into early autumn
  • Easy-to-assemble
  • Feeding attractants bring in more beetles
  • Can cover an entire yard

Cons

  • Replacement lure and bags sold separately
  • One bag will fill quickly in areas with high Japanese beetle populations
  • Lasts an entire Japanese beetle season
  • Easy lock bottom conveniently opens to drop beetles and closes back
  • Large catch capacity

This product only uses a floral lure and trace amounts of sexual attractant but scores high points for the reusability factor of the bag. When the bag fills to the top with beetles, instead of disposing of the bag and replacing it, you simply unzip the bottom over a trash can and close it back to rehang. 

This convenience and cost-saving factor are also backed up by the design of the inside of the bag. Once Japanese beetles land on the valve, the overpowering scent of the lure causes them to fall inside of a funnel that they cannot escape. 

This bag should be placed within 30 feet of the targeted problem areas in the yard. The bag is well designed and easy to prepare for use. The material of the bag is made of durable nylon and each one comes will all the accessories you need. There is no need to buy anything else.

We recommend this product based on the convenience it offers and the superior design of the trap. 

Pros

  • The bright yellow panels and the attractants will draw in large numbers of beetles
  • Attractant cartridge and the bag lasts an entire season
  • An all-in-one trap that requires no additional accessories
  • Wide coverage area

Cons

  • Uses more floral lure than pheromones
  • Bag fills quickly 
  • Dual attractants with a controlled release system
  • Large collection bag
  • Lasts an entire Japanese beetle season

A frequent problem homeowners encounter with Japanese beetle traps is the small size of the bags. This product avoids that problem and comes with two large-sized collection bags that take longer to fill to capacity. 

This trap also uses a dual-acting set of attractants that targets the mating cycle and feeding habits of the Japanese beetle. The trap is easy-to-assemble: attach the attractant pack to the side of the trap vine and hang one of the large bags on the hooks at the bottom. 

Once the beetles fly to the attractant pack, they will fall into the bag and the hourglass shape will prevent the pests from crawling or flying out. Another convenient feature with this trap is the inclusion of a steel stake that can be placed within 10 feet of targeted areas. 

Pros

  • The attractants are time-released to last up to 13 weeks
  • Stake, lure, trap vine, and 2 bags are included
  • Dual-acting attractants
  • Easy-to-use and convenient

Cons

  • The bags can tear
  • The attractants release slower
  • Lasts all season
  • Offers up to 5,000 square feet of protection
  • Contains 1 trap, 1 dual lure, and 2 disposable collection bags

Bonide is a trusted name in DIY pest control, and its Japanese beetle traps are no exception to overall customer satisfaction. This product also has a dual-acting pheromone/floral lure attractant and is shaped like an hourglass to keep the beetles trapped inside once they fall in. 

This product is better suited for smaller yards or one garden that may need treatment. So if you need to cover only a small area, this product is great. It advertises up to 5,000 square feet of coverage, but the trap is a little smaller than the ones above. 

This trap comes with two bags and is easy to suspend from a stake, bush, or small tree limb. Just make sure to keep the trap at least 30 feet from the plants or flowers you want to protect so as not to draw in more beetles to the area. 

Although smaller and less fancy, this trap works well and is one of the easiest to assemble and handle on the list. 

Pros

  • Lasts the entire Japanese beetle season
  • Covers up to 5,000 square feet
  • Ideal for smaller areas needing protection from Japanese beetles
  • Comes with a spare collection bag

Cons

  • Smaller in size
  • The collection bags are small and fill quickly

Final Thoughts On Japanese Beetle Traps

Effective Japanese beetle control requires a full spectrum methodology of traps, grub eradication using beneficial nematodes, milky spores, and even hand picking them off your plants to get rid of them. No single method by itself is enough.

Row covers, the use of insecticidal soap, and drop cloths are additional methods to use against these garden pests. To learn how to put it all together, read our next article in this 2-part mini-series, How to Get Rid of Japanese Beetles.
