UV Moth Trap, Indoor


The indoor MOTH +Phototactic Trap is an indoor version of our popular UV Moth Trap and uses harmless UVA light, to lure insects into a collection chamber for removal from indoor structures. Simple and effective using no fans* or smelly baits – just silent effective collection capitalizing on the moths natural phototaxis (attraction to sources of light).  The indoor MOTH +Phototactic Trap is highly effective at capturing moths for entomological study or for luring nuisance pests away from living areas.

*New for the 2024 Moth Season! Our indoor trap is now available with our Active Collection / Kill electronics, or our Classic No Kill version. Our Classic No Kill Traps feature passive collection where moths are enticed to bed down for the night, within the trap and should be serviced (emptied outdoors) each morning. By contrast, our Active Kill Traps feature an active collection draft, that both collects and retains the moths within the trap, where they dehydrate and die. These traps can see weekly or monthly service, depending on your pest load. All Active Kill Traps feature 5VDC electronics and are supplied with a 120VAC adapter.

New! Active Collection / Kill Trap Details

New for the 2024 Moth Season! Our indoor trap is now available with optional Active Kill electronics. Using the same MOTH +Phototactic attraction concept as our Classic No Kill Trap (details below), our Active Kill Traps feature a quiet powered draft, that both actively collects and retains the moths within the trap, where they quickly die, due to lack of access to moisture. As a result, Active Kill Traps do not require a collection ‘habitat’ media and can see extended weekly or monthly service intervals (depending on your pest load). All Active Kill Traps come equipped with our large surface area UVA LED (5VDC) Lamp and Oversized Collection Fins, Vented Collection Funnel, Active Kill Powered Draft (5VDC) and 120VAC dual receptacle adapter.

Active Kill Traps are suitable only for indoor use and are ideal for “scrubbing” local areas of nuisance moths. The collection screening is sized to promote the entrapment of Army Cutworm / Miller Moth that would otherwise not be collected, in a more broad spectrum, finely screened, commercial insect trap.

Classic Passive Collection / Kill Trap Details

How our Classic No Kill Traps Work: The MOTH +Phototactic Trap is ‘baited’ with a light source that is tuned to be particularly attractive to certain species of moths.  Flight interruption fins surround the light,  insects will be draw in and will circle the light, they eventually impact the structure.  The impact disorients the insects, dropping them through a collection funnel and into the chamber below.  Within the collection chamber the insects quickly seek refuge among a habitat structure (recycled egg cartons work great!).   Collected insects can then be observed alive, or various killing methods can be employed, depending on the users needs.

Suitable for Indoor Use: This indoor version of our MOTH +Phototactic Trap is made from high impact PET-G plastics and features stainless steel hardware, an attractive white lamp lamp socket and cord with on-off switch.  The trap is baited with a bright UVA emitting LED lamp (60W equivalent) that runs cool using only 5W of power.  The low power usage makes it particularly easy to power using widely available and affordable portable inverters.  Requires 110-120VAC power source.

Assembly Instructions

  1. Unpack and inspect the contents of your MOTH +Phototactic Trap
  2. Install the provided UVA lamp into the lamp socket.
  3. Gently press-fit the flight interruption fins within the slots around the lamp.
  4. Remove the base of the collection chamber, it simply twists off.
  5. Cut the top portion of your recycled egg carton (not supplied) off and discard.  Now cut the remaining egg crate portion of the carton in half and stack these randomly (but so they do not nest within each other) within the base of the collection chamber.
  6. Reinstall the base, loaded with your egg carton, to the collection chamber.
  7. The trap is most effective when placed on a table top away from curious pets and competing sources of light.
  8. Plug in the trap, turn on the light switch and let the moth collection begin.  Collection will be the most
    active between dusk and dawn.
  9. Traps should be inspected or emptied in the morning.  Turn off the UVA lamp and unplug the trap from power before doing any inspections.  Gently transport the trap outside and separate the base from the bucket to release the moths.
  10. Moths will be found in and amongst the folds of the egg crate collection ‘habitat’ within the collection chamber.

Collection Advice

Place the trap in an area where collection is desired and moths are believed to be present.  The trap functions best when it is the sole source of light in the area, turn off competing sources of light both outdoors and within structures.  If additional lighting is required in the area, use amber colored “bug lamps” as these are less competitive with the blue light source of the trap.

By design the MOTH +Phototactic UVA  Moth Trap is a no-kill moth trap.  This means that collected insects can be observed alive after collection.  As many moths are great pollinators and a food source for birds, bears, etc. a compelling argument can be made for using no-kill methods of collection and release.

For no-kill removal of nuisance moths, place a trap well away from entrances to structures, to lure the moths to take up residence in your trap, rather than inside your home.  The moths will be free to come and go, from the trap without intervention.  When collecting nuisance moths indoors, unplug and gently remove the trap to an outdoor area before removing the top for inspection or release.

Kill methods.  As compelling as some no-kill arguments are, there are times when both entomologists and homeowners alike, may wish to employ a kill method.  On our farm, we simply remove the traps to our chicken run, releasing the live moths to the chickens where some escape, but the majority are quickly dispatched by the birds.   But there are other ways to dispatch the moths.

Ammonium Carbonate as a killing agent.  Ammonium Carbonate is readily available from online and local sources.  It is used in baking as leavening or as smelling salts.  Placing dry ammonium carbonate in a shallow dish within the trap has been found to be an effective kill agent.

Ethyl Acetate is another common killing agent, ethyl acetate is found in non-acetone varieties of nail polish remover.  The liquid can be placed in small glass or metal canister with a large cotton wick placed in the liquid.  The wick should extend above the canister.  The fumes released have been found effective at killing the trapped insects.


Cautions: UVA light is considered harmless to humans and the UVA emitted from the included lamp, is far less powerful than that which you are exposed to on a sunny day.  Still, it is never a good idea to stare directly at the UVA light as discomfort and temporary spotting of your vision may result.  This product is not intended for use by children ages 12 or younger.  Always unplug the product from the power source prior to doing any manipulation or inspection of the trap.
