The smaller, yellow black striped ones with short tempers have built a nest on the Hoya. This is the second time, but this time they've managed to get a much larger colony going. Has anyone tried using the soapy water method on these? If you have and it was successful, what's the ratio of detergent to water to use? I don't want to use the petroleum sprays on the plant, but I need that nest gone. Thanks for any tips on getting that done while leaving the plant intact.
