Bees can sometimes establish hives inside wall cavities which requires treatment quickly as some people are highly allergic to bee stings.
Treatment to the wall cavity will eliminate the bees, however the temperature of any honey they form is regulated by the bees. Once the bees are dead, the honey (if the hive has been active for a long period of time) will run down the inside of the wall cavity possibly creating a problem by attracting cockroaches and ants.
The warmer months are when bees tend to create a problem in and around buildings due to swarming. Bees can become very aggressive if disturbed, so do not spray them with aerosols or try to knock down an active hive. Our technicians are trained to treat bees effectively whilst wearing protective equipment to minimise any risk.
Only native honey bees do not sting, so treatment of this species is not necessary.
Wasps, unlike bees will not die after stinging and can sting several times. They are also sometimes mistaken for bees as they have similar colouring. Nests can be found in locations such as wall ventilators, tree cavities, retaining walls, brick cavities etc. and are treated directly by using a spray, powder or aerosol.
The two species most common in Sydney are the paper wasp and the European wasp. European wasps are much more dangerous and should be avoided, please do disturb the wasps as you will most likely be stung.
Mud wasps are not aggressive and their nest pods may be knocked down.
