Which statement about exterior lights is accurate?

The statement that bright security lights can attract a large number of insects is accurate because many insects are naturally drawn to light sources, particularly UV lights. This phenomenon is rooted in the behavior of nocturnal insects that use light from the moon or stars for navigation. Artificial lights, particularly bright or high-intensity ones, can confuse and attract these insects, leading to an increase in their presence around lit areas. This can be a consideration when planning outdoor lighting for a property, as it may lead to unexpected increases in local insect populations, which can affect both the comfort of outdoor spaces and the overall ecosystem.

The other statements do not hold true in this context. Small lights may not be visible from great distances, but that does not hold true for all types of small lights or all visibility conditions. Insects that are attracted to lights can indeed enter buildings, especially if doors or windows are open or if they are drawn close to the building itself. Lastly, while security lights may have some deterrent effect due to brightness and visibility, they are generally not effective at significantly deterring insects; in contrast, they often attract them instead.
