The answer to 'why is my landscape lighting pests' is that landscape lighting can attract certain types of pests, such as insects and rodents. The bright lights can draw in bugs like moths, mosquitoes, and other flying insects, which may then become a nuisance around your home. Additionally, the warm glow of landscape lights can attract small rodents like mice or rats, who may try to nest near the light sources.
To prevent pests from being attracted to your landscape lighting, consider using LED bulbs that emit less heat and light, and aim the lights downwards rather than allowing them to shine upwards. You can also try installing motion-sensor lights that only turn on when needed, rather than leaving them on all night. If you continue to have issues with pests, it may be best to consult a professional pest control expert who can assess the situation and recommend appropriate solutions.
