Bee removal from wallsHoney bees that swarm usually make their new nest in a hollow tree or in an old man-made hive. However, they are attracted by attics and wholes in house walls and therefore a house owner should not be too amazed if he/she finds a bee family in the least used parts of the house. Bee removal from walls is quite a tricky and dangerous action and therefore it is advisable to seek assistance from a professional beekeeper or a bee removal company.
A proper bee removal from walls might imply the work of several professional. Thus, you might need to call a beekeeper to move away the colony, a carpenter to disassemble and then reassemble the wall and even an insect removal company to kill the family if the bee removal process cannot be done in safe circumstances. If the nest is positioned near the pipes or the electric installation it is better to have a plumber or an electrician around. Since honey bees are such valuable insects their destruction should be the ultimate solution.
The correct identification of the bee type and of the nest positions provides useful information to be used in the bee removal from walls process. Thus, bumble bees do not usually build a nest in the cavity of a wall; they prefer insulation materials or you might even find them in the seat cushions. The yellow jackets are attracted by cavities in the walls or by attic or ground holes. Honey bees on the other hand will definitely build their nest in wall cavities of old houses since they are not exactly insulation materials fans.
Bee removal from walls is quite a complex process. The first step is to correctly identify the location of the bee family nest. The house inhabitants should avoid doing any activity in front of the nest entrance. Honey bees usually sting when they are disturbed since they perceive the disturbance as a threat to their safety. When leaving the hive, honey bees have the tendency to fly upwards. Thus, if the entrance is higher than 10 feet there should be little problem if you pass by the hive, however it is better to avoid walking or other activities around the hive.
Observing the bees is another action to be done when deciding to go for bee removal from walls. If the bees are just flying around a wall opening they might be just scout bees looking for a new home. If the bees go in and out from the opening and have yellow sacks on their legs, it means that there definitely is a honey bee nest inside your wall. The absence of pollen in their sacks indicates that the bee family has just moved in for about a day or two.
It is not advisable to plug the holes when doing bee removal from walls, since the honey bees might find a new way out and this new rout might lead them directly into the house. Honey bees can be safely removed either by trapping them or by disassembling the wall. The best time for bee removal from walls is either late winter or the early spring months. In this period of the years the honey bees are less aggressive since they have already consumed the honey they stored for the winter and they are by far less numerous as they are in late spring or in summer.
Bee removal from wall should be done by a beekeeper. There are beekeepers that remove bees with the help of a special vacuum. This device does not kill or harm the honey bees. A bee vacuum sucks up the insects and also manages to reduce the congestion of honey bees that fly all over the place. It also allows the beekeeper to collect most bees without have to return a second time for the hive. A bee vacuum might be home-made or purchased from a beekeeping store or web site. Even with a high tech vacuum the process of bee removal from walls might be quite laborious because of the construction material, house positioning or other elements and factors. In some cases bees have to be killed. The eradication process has to be done in two and even three phases since in the beginning only the adult bees are killed while the eggs and the pupa survive. Therefore, the bee exterminators have to return several times to make sure all honey bees are dead.
If the bee colony is not a threat for the house inhabitants it is better to leave it alone. Most time unattended bee families die because of starvation, improper weather conditions and typical honey bees' diseases. When the bees are dead it is advisable to seal the entrance so as to make sure that no other swarm will rush in attract by the bee odor that persists quite a long time after the extinction of the colony.
Bee removal from walls can be done by draping the bees. The beekeeper reduces the hive entrance and positions in front of the nest an exit cone. This device looks like a funnel. The cone has a very small exit at its tip thus allowing the honey bees from leaving the hive but preventing them from re-entering. In order to make the trap complete a nucleus is placed in the vicinity of the cone. The nucleus contains several frames with brood, frames with honey and a queen bee. The bees that live in the wall will eventually join the nucleus. This is a very long and time consuming process that might last for months, depending on the size of the colony in the wall.
In spite of the dangers implied, homeowners might decide to do bee removal from walls with no professional help. The most efficient solution is to use aerosol pesticides that have into their composition pyrethroids. The spaying should be done in the evening not during the day when the bees are active and when many of them are out of the hive in search for food. In order to make the whole process more effective a homeowner might drill some holes in the wall in the vicinity of the nest and then spray through them the insecticide. The insecticide might not be very useful and efficient if the nest is located too far from the wall opening. The pupas are protected by wax and therefore they do not die when in contact with the poisonous substance. For this reason the whole process has to be repeated in three weeks.
After exterminating all bees the entrance has to be sealed since the honey and the combs in the walls might attract other swarms. The honey and the combs should be removed too, if it is possible. Bee removal from walls a quite complicated process and therefore it should be done with utmost care and by specialists in the domain.
