About beehive

Nests are built in various places, such as under eaves, tree branches, attics, door bags, and soil. Bees will attack if they approach the nest inadvertently, touch the nest, or vibration. When pruning trees, make sure that there are no beehives.
If you are about to be attacked, lower your posture and leave it as soon as possible. When hiking, don't step outside the mountain trail. Also, wear dark clothing with salmon hats, as black objects are more likely to be attacked.
Bees stop active when it gets colder and disappear in winter. In addition, beehives are limited to one year and will not use the same nest in the next year.

If you have any problems with beehives, please contact us!

From July to October, there are many consultations on beehive control. Finding and exterminating beehives early can minimize damage. Let's be careful if there are no nests in houses.

Places where bees are easy to build nests are the ceiling, under the eaves of the roof, in door pockets, and in planting.
