Garden trapping


Trapping the Asian hornet, outside of apiaries, requires a different approach. The reason is simple: Hornets don’t come with the same intention. What they are looking for in a vegetable garden are carbohydrates, whereas in the apiary they are looking for proteins.

For individuals who do not have a hive but who cultivate a garden, maintain a park, planters on terraces or balconies with flowers, here are the different plants, fruit trees and smells that attract Asian hornets:

Fragrant Plants: Asian hornets are attracted to plants that give off strong, sweet odors. For example, Buddleia, commonly known as “butterfly tree,” can attract them because of its sweet scent. (let us know your observations)

Nectar-rich flowers: Flowers that produce a lot of nectar can also attract hornets. Among these, we find certain varieties of flowers, such as geraniums and hollyhocks, ivy flowers. (let us know your observations)

Fruit Trees: Asian hornets are particularly attracted to fruit trees, especially when they produce ripe, sweet fruit. This includes fig, cherry, apple and pear trees. (let us know your observations)

Nectar from certain flowers: Asian hornets may be attracted to the nectar of certain flowers, including rhododendrons and azaleas. (let us know your observations)

But in this context, offering them carbohydrate bait may not be a viable strategy. If the sources of carbohydrates present (think of a vine or a fig tree for example) are omnipresent, your bait will really have to have some advantages to show off!

As a result, trapping approaches are much less monolithic than in the apiary.

In what follows, we have therefore taken the option of sharing experiences.

Vines and waxes:


At home, a trap placed on the vine proves to be of no effectiveness, while the hornets in saraband gorge themselves on grapes. But at the same time, another trap located 5 meters from the latter, next to a warehouse with beehives and waxes, is a hit!

Apple trees and camellias


At first, under an apple tree, I was disappointed by the low number of individuals trapped.

Secondly, I was very pleasantly surprised this fall by a capture made with 3 traps under a camellia.

One of the traps captured 123 individuals in 48 hours! I did not count the captures of the other traps but this corroborates your experience: multiplying the traps even on a small volume is interesting (my camellia has a small volume compared to my apple tree which must explain the difference in results, with in plus the fact that food is currently scarce).

Another interesting point to highlight: I captured 3 non-Asian hornets under my apple tree (easily identifiable with the difference in size and color of the abdomen).

My latest traps are made exclusively with paper towel sheets soaked in grenadine and it is with this combination that I have the best results (better than with cotton or dry herbs that you mention).

I observe that hornets come to rest against the entrance to the trap and seem to exchange impregnated paper crumbs with their fellows inside. So I ask myself a question: I know that the nicotine contained in tobacco is fatal for insects, perhaps we should make a decoction of tobacco leaf mixed in a very very small dose with grenadine: with a little luck some of this nicotine would be carried into the nest and have a negative effect on the colony…  (we are deleting this sentence as we do not understand “tobacco principles”

Last remark which surprised me very much: for the counting, I placed the jar in a bucket of water one night.

The next day I spread the hornets out on a table and after two hours in the heat, around 30 individuals began to move… and therefore were not dead!


Petrena and Jonathan

We can tell you that now your trap is working! For the past week, below the fig tree, where there are many Asian hornets, we have been catching between 10 and 15 per day. No more, but still, it works. We use straw,  two small pieces of ripe fig, a small spoon of honey, and a little bit of lime syrup. But the European hornets also come in, too bad.

The last two weeks, with the sun and the heat, there were a lot of hornets in our fig tree. Why the trap works now, I don’t know! But the success absolutely encourages us to try next year, and with different things in it, if necessary.
