Garlic is a pungently odoriferous member of the allium family (like onions and leeks). Garlic is generally used as a spice or a seasoning rather than as a vegetable due to its extremely strong flavour. Garlic grows in large papery heads. A novice mistake is to massively overgarlic things by following instructions incorrectly. Remember that the large bulb of garlic you buy is NOT one 'clove'. The whole garlic is called a 'head' or 'knob'.
Bumblebees do not damage brickwork or wood. Some of the bumblebees which make smaller nests, Bombus pratorum and B. hortorum do sometimes chose strange places to nest. Their nests are small and in the case of B. pratorum are usually very short lived.
most bumble bee stings occur when their nest is disturbed yes the worker bees and queen bee in a bumble bee colony are capable of stinging bumble bee colonies are organized around a queen bee who can also sting drones male bees and worker bees worker bees are sterile females and are able to sting because the ovipositor has evolved into a stinger
