Ecological pest control in Hong Kong? Yup. BioCycle offers a safe alternative with its tailor-made packages that treat and prevent a wide range of pest problems. Its line of Swiss-formula pesticides with very low doses of active ingredients is biodegradable, non-staining, non-flammable, and targets only cold blooded insects. You won’t even have to leave the treated areas after spraying! It’s also odourless and free of nasty VOC’s (volatile organic compounds) and you don’t want those.
