We tend to use wasp traps only when the ripe fruit is on the trees: it is not enough.
In fact, vespas and hornets are greedy for figs, apples, pears and other sugars that our orchard offers, but what we do not know is that the use of wasps traps is only possible when the fruit is ripe.
It is certainly useful to catch hornets who eat the fruits of our work, but for them the fruit is just as greedy as the bait of our trap and we risk reaping just as ruined fruits, despite the traps full of insects.
To attract hornets, wasps and asian hornet (Vespa velutina) - Tap Trap
Mix 2 tablespoons of sugar or honey with ½ litre of beer.
Alternatively, mix ½ litre of water with three tablespoons of sugar or honey and a glass of vinegar.
Alternatively, blend sweet white wine (or white wine sweetened with sugar or honey)
with 20 to 30 millilitres of mint syrup (roughly equivalent to a small glass).
To attract hornets, wasps, asian hornet (Vespa velutina) - Vaso Trap
Mix 2 tablespoons of sugar or honey with 350 ml of beer.
Alternatively, mix 200 ml of water with three tablespoons of sugar or honey and a glass of vinegar.
After placing two 1.5V AA batteries (not included) in its battery compartment, insert the luminaire into its bracket inside one of the semispheres, then assemble the sphere.
Before applying the glue, wrap the sphere with a transparent plastic film (such as cling film, or two clear shower cups); then apply a suitable glue.
Suitable glues range from sprayable to brushable, specific for insects and tube glue (such as mouse glue), all of which are available in garden centres and specialised stores.
In the event of loss of adhesion, the glue can be reapplied several times.
In addition to using only glue, or glue and attractants on it, Sfera Trap™ can also support insecticides and pheromones.
Practical advice: Use disposable gloves in the preparation of the sphere and the various products used. To avoid damage from possible spillage of glue, place a protective sheet underneath the sphere, such as cardboard or paper. In the eventuality of glue spillages these can be removed using white spirit or turpentine.
