Here in SA I have been finding it difficult to find suitable sticky pads for catching flying bugs that have become a real problem this year in amongst my orchids in particular my Cymbids
So a little while ago I started making my own and have been quite surprised at just how effective the pads are proving to be.
My method is to cut the sides out of a cereal box , punch a 20 mm hole into the centre and insert a LED into the hole . The LED'S are wired up , using a thin insulated copper wire , in series. I then coat the cereal box sides on both sides with PSA adhesive. Be careful with this stuff it is incredibly sticky and difficult to get off your hands, I wear surgical gloves when working with it .
The LED's are powered using a rechargeable battery and when all lit up at night look very pretty. the lightes then attract the bugs to their DOOM
While on the subject of killing bugs, I have recently read a number of articles about commercial growers in OZ and New Zealand losing their cymbid flowers due to defective or badly formulated insecticides for mites
I have also experienced this to some extent this year for the first time , in desperation I used an insecticide for white fly and this stuff has deformed some of my cymbid flower buds . This is the main reason for me experimenting with sticky pads. As most bugs have a flying stage, I am hoping to reduce the use of insecticides over the next year .
