Light pollution is a serious problem for local wildlife, that get disorientated and confused by excess light at night. Moths, bats and all nocturnal insects have evolved to use the darkness, stars and moon to navigate, feed and find a mate. Considering some have extremely small life cycles, a single night is valuable. Leaving garden lights on at night doesn’t only use up energy and cost money, but can be devastating to local wildlife. Studies have also shown that security lights have no correlation to preventing burglaries or vandalism.
If you’re not in your garden or outside space, turn off your outdoor lights. Make sure lights are off in rooms you’re not in and that curtains are properly closed in those that you are. This stops insects being pointlessly drawn to your windows. Maybe consider upgrading to black out blinds and curtains. Most importantly, make sure all lights inside and out are off when you go to bed. You will save energy, money and the nocturnal ecosystem around you.
