The little known Australian blue banded bee, is a bee unlike what we are used to thinking of bees. These bees are solitary, they leave in holes in the ground, or rock fissures. They're of great interest in pollination, because the buzz pollinate, which means the flurry of wings starts the process. Anyone who loves their tomatoes, chillies, eggplants, blueberries and cranberries will love these bees, as they are so good at pollinating these varieties. These bees have no sting, nor do they swarm, so this in itself makes them welcome, especially for those allergic to bee stings. One look and you're hooked on the beauty of these bees, the colour is gorgeous, what a treat to have them in our garden.

Helen McKerral writing for Garden Drum says-Avoid pesticides (including organic ones) as much as possible. I personally particularly avoid all of the chemical neonicotinoid insecticides (Confidor, Resolva bug sprays) because of their effects on bees. Because these insecticides are systemic (circulated throughout the plant) and get into the pollen, you can’t avoid poisoning bees by spraying at any particular time of day, or using tablets pushed into the soil. While these insecticides are unlikely to be the sole cause of mass bee deaths in the USA (spurring a pre-emptive 2-year moratorium on their use in Europe and a ban in Oregon), they are definitely implicated. Nor is it surprising that USA corn farmers are eager to continue using this undoubtedly effective chemical regardless of its possible effects on bees, because corn is wind pollinated! However, unlike farmers in broad scale agriculture, home gardeners have plenty of less toxic options available, so it is common sense and easy for us to err on the side of caution even if our own government won’t apply the precautionary principle as the EU has done.
