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.
These man-made structures are typically referred to as beehives. Several species of Apis live in hives, but only the western honey bee (Apis mellifera) and the eastern honey bee (Apis cerana) are domesticated by humans. A natural beehive is comparable to a bird's nest built with a purpose to protect the dweller. The beehive's internal structure is a densely packed group of hexagonal cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae).
