Phermone-based Clothes Moth Traps
The use of pheromones for biological pest management is an ingenious alternative to using harmful chemicals.
Insects of the same species communicate by releasing small quantities of chemical substances into the air. These distinct pheromones (i.e. scents) attract others to the source of that attraction.
It is now possible to communicate with certain insects with synthesized pheromones, attracting them and disrupting their normal behaviour.
Webbing Clothes Moths
This moth measures about 5mm in length and is straw-coloured with no distinctive markings on the wings. The larvae are tiny white ‘caterpillars’ with brown heads. They cause considerable damage by feeding on articles containing wool, mohair, fur, hair, feathers or other products of animal origin.
Female moths lay between 100-300 white eggs on fabric surfaces, which hatch about 5 days later. The larvae feed on the fabric, leaving webs or tubes on the surface, and continue to develop over the next 6 weeks. The larval development time is much longer under cooler conditions. The period of greatest moth activity is generally during the summer months.
Traps are tent-like houses that are glue-coated. They are suitable for both indoor and outdoor use.
Available Combinations:
- 1 trap + 1 pheromone lure
- 1 pheromone lure
Traps are part of the solution
The most important aspect of control is careful sanitation such as washing, dry-cleaning, vacuuming and brushing articles that are likely to be attacked and, where possible, storing them in moth-proof containers. Cold storage of 5.5°C or extreme heat of 43°C or higher will also destroy these insects. Another means of protection is to place cleaned articles in cedar-lined closets, where the cedar oil content is high. Moth traps are not effective at the larva stage, so make sure to clean as well!
Assembling your trap
The assemblage of the moth traps is very easy and quite quick. Just pull the base downwards, creating a diamond shape. Place the accompanying lure inside, near the middle of the trap, on the glue. Fold in the ends at the bottom and place the trap near the location where you believe the moths to be.
Lures: How they work, how and when to replace
The lure you are using is a controlled-release device that allows pheromones, distinct species specific scents, to be released at a constant rate over a period of time. All pheromones are sealed in impermeable pouches and cold-stored, so if you have purchased extra lures, please refrigerate until time of use.
If you are purchasing just lures, we would recommend against placing new lures into traps without first removing the old ones, as adding new lures to a trap with old lures still in place will bring about a concentration change in the release level of pheromone from that trap. On the face of it, that may seem just fine, but unfortunately " more is not better" in this case, since the higher levels of release do not necessarily improve the attraction of the insect. In fact, the reverse can be true, since the higher level can actually be slightly repellent.
The pheromone lures should be taken out of the sealed package with minimal handling and placed on the floor of the trap. You should aim for a constant pheromone release rate, so that any changes in trapcatch reflect the insect activity, not changes in attractancy. During the first 6-8 weeks, the release rate of pheromone tends to be constant, so changing the lures on a regular basis within that period will give you a constant level of attraction. Lures are formulated and loaded with considerable accuracy in order to give you that constant release rate, so by working with that in mind, you can reduce the variables and make the traps most effective.
Trap Placement
Hang the trap in areas where insect presence is suspected and inspect twice a week. If there is no catch, try moving the trap to a different location. If insects are being caught, leave the trap in position and add additional traps as needed. Catching and trapping adult moths will affect the reproduction and development of further larvae.

I sound like an infomercial but I did try all sorts of moth traps including moth balls to no avail. Within a few weeks, I had rid my closets of moths which had been destroying all my wool clothing. I would highly recommend these traps to anyone with a cloth moth problem. The fact they are non-toxic to pets and humans is just an added bonus in my eyes. Plus you don't make your closets or rooms smell aweful.
