Then there is normally an argument and I have to go and remove the second swarm. Over the years, I have learned a few tricks to assist in bee prevention. We will go into these in this article.
If you have a piece of prime bee real estate, bees will keep returning to that place. After removing a bee nest, it is important to make the space “unattractive” or “invisible” to the bees. This is the domain of bee prevention.
In the case of ventilation spaces, and air bricks, and similar structures that are designed to enable airflow, ensure that these are screened completely with a stainless steel mesh.
These are normally used to control ants and cockroaches. If you mention that you have an area in which ants, bees, and cockroaches periodically nest this will help.
An alternative method of bee prevention is to place catch boxes near problem spots. These baited hives will tend to be even more attractive than the problem cavity. In this way, as soon as bees move into a catch box, we remove the swarm and replace an empty box.
