Vespa crabro, vespa mandarinia, vespula germanica and common wasp
We may wrongly think that the use of wasp traps is necessary only when the fruits in our orchard are ripe.
Whilst wasps and hornets do love ripe apples, pears and other sugary fruits, we need to catch these pests before they begin eating the fruits and thus damaging the harvest.
Hence, it is necessary to place the traps in our Orchards before the fruits begins to ripen. If we wait too long, we risk reaping only blemished fruits, all the while witnessing the successful mass trapping provided by the traps.

After inserting the two 1.5V AA batteries (not included), insert the luminaire into its seat inside one of the semispheres. Sfera Trap is now ready to be assembled - How to do it
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.
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 - How to do it
