BYOB UV Moth Trap Kit, Weather Resistant

(1 customer review)


SKU: BYOBTRAP/WR1 Categories: , Tags: , , ,


How it works: The BYOB 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 / Outdoor use: The MOTH +Phototactic Trap is made from high impact HDPE and PET-G plastics and features stainless steel hardware and a weather rated UVA LED lamp.  The trap is baited with a bright UVA emitting LED lamp 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 or 5VDC power source depending on model purchased.

Assembly Instructions

  1. Unpack and inspect the contents of your BYOB MOTH +Phototactic Trap Kit
  2. Use a fine-tipped permanent marker to transfer the cut and drill pattern, from the provided template, to the lid of your collection container.
  3. Carefully cut the top of our container to match the transferred lines of the cut template.
  4. Drill your container top using the drill pattern provided on the template.
  5. Install the collection funnel into the cut lid of your collection chamber and secure with 5 each of the provided 4-40 x 3/8 inch screws, washers and nuts (snug the hardware but be careful to not overtighten).
  6. The lamp socket and bulb are pre-installed.  The lamp cable should extend over the top edge of the funnel and will be secured by sliding the strain relief clip over the cable and securing the clip to one of the funnel mounting holes, using the longer 4-40 x 1/2 inch length screw.
  7. Gently press-fit the provided flight interruption fins within the slots around the lamp.
  8. Gather up 3-4 recycled egg cartons (not supplied), cut the top of the carton off and discard.  Cut the egg crate portions of the carton in half and stack these randomly (but so they do not nest within each other) in the bottom of the collection chamber.
  9. Set the completed lid assembly with funnel, lamp and fins on top of your collection chamber.
  10. The trap is most effective when placed on the ground, but if used around livestock it will be necessary to hang it in an area protected from curious animals.
  11. Plug in the trap and let it do its work.  Collection will be the most active between dusk and dawn.
  12. Traps should be inspected or emptied in the morning.  Unplug your trap from power before doing any inspections.  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.

    We bought this for moth trapping while camping and tried it out for the first time in Joshua Tree last week. It was amazingly effective! We caught tons of moths of a variety of different species. My young son loved waking up in the morning to see what we caught overnight. It was like Christmas every morning! I highly recommend this for any amateur entomologists. It’s easy to use, light, portable, and effective!


      That’s awesome!!! – We are thrilled that budding entomologists are using our no-kill traps to great benefit. Thank you for your feedback. -Doc
