Tips

  • Note that if you intend making more than one molasses trap, you will need to increase the ingredients or make several batches.
  • This is likely to be effective only in your backyard. If you have an apple orchard infestation, talk to the professionals. Organic control is very hard but it is possible. Latest technology uses pheromone traps (mating disruption lures) to disrupt the moth's breeding cycle.[2] There is also the possibility of using parasitic wasps but you should seek professional advice first.

Warnings

  • The corrugated cardboard and molasses trap methods will only work if you are diligent in removing the items and replacing them with fresh versions regularly. The aim is to reduce the population considerably in one season, so that there will be less infestations in subsequent years. Be diligent in following years also, or likely you will suffer a reinfestation.

Things You'll Need

  • Corrugated cardboard
  • Plastic milk container with handle (large size) (as many as you need traps)
  • Scissors or knife
  • String for hanging and tying on cardboard
