Air bricks provide subfloor ventilation to a suspended timber floor. It is important the air bricks are not obstructed or blocked in any way way as that would hinder the cross flow ventilation to the sub floor which could potentially lead to damp and decay issues to the timber joists in the future.

If you see bats around the area in which you live that is actually a good sign as bats are indicators of a healthy environment. Bats need places to roost, clean water to drink and lots of insects to eat, therefore seeing bats around suggests that your local area has lots of good habitat that will support a whole range of wildlife and they will also keep the insect numbers down.
At a bat roost last night we counted over 110 bats emerging from this one single roost. It is always pleasurable watching bats come out and hunt around in the garden catching insects. Why not invest in a Hetrodyne detector which you can use to actually hear the bat's echolocation calls. Get your children involved in counting the bats as they emerge from their roost and listening to them.
Your local bat groups will often arrange bat walks in the evening, so why not join them to learn more about these fascinating little creatures.
