The fungus gnats who annoy me with my houseplants, fly it and stick ... so far so good. I am an animal lover and have always held so if I have to kill an animal, never to let it suffer long. I have trouble seeing how fungus gnats (which for me also animals), the stick with his legs, even after 30 hours still desperately (and because of the good adhesion in vain) attempt to get away again. They are likely to be starved to death or died of thirst excruciating after a few days.
I had expected to fix the purchase so that the adhesive mixture would added a natural toxin, so that the insects that stick out die after a few seconds. Unfortunately that is not so - therefore the points deduction.
I combine my fighting tactics with Culinex tablets that are dissolved in the irrigation water, so I sincerely hope that thanks Culinex time slip no more fungus gnats and so does not die in agony on the yellow plug.
Who has no moral concerns, can be accessed at the natures yellow connectors - of the effect alone a clear 5-star product. The manufacturers of the yellow connector I would really ask you to consider whether we could not give a natural, harmless to humans and plants poison in the glue mixture, so that the insects quickly die on the poison and not miserably perish in agony.
