How to Keep Moths Attracted to Light Outside

When it comes to sources of light, moths aren't picky -- they will fly around light bulbs, flames and anything in between. While this behavior usually is unwelcome, some people want to attract moths to their yard to study or photograph them. A simple light source will cause some passing interest in moths, but maintaining a significant moth presence requires encouraging moth activity with baits, plants and proper timing.

Instructions

    • 1

      Use black lights or mercury vapor lamps instead of incandescent lamps to attract more moths. Cover the lights with a glass barrier to prevent the moths from flying directly into the hot surfaces and injuring themselves.

    • 2

      Plant flowers, especially near your light sources. If you notice moths congregating around specific types of flowers, choose those over other species.

    • 3

      Soak a fabric rope (such as paracord or a bungee cord) in inexpensive red wine. Hang the rope near the light sources or near trees to attract moths.

    • 4

      Create a moth bait by mixing a can of beer, 1 1/2 cups of sugar, one-fourth to one-half cup of molasses and several overripe fruits (such as apples, bananas or peaches) in a blender. Allow the mixture to age for several days in a partially sealed container. Spread the bait on trees near light sources.
