I had been trying for over 2 years to get rid of Woodworms from my wooden roof without success using similar products from other companies, but mainly using oil. Firstly, I have to say that the other products didn't work at all, while the oil somewhat alleviated the problem as I noticed dead woodworms on the floor after using it. However, the problem persisted as even after the next day from applying the oil, I still heard the familiar creaking sound that experts call "Greek saraki". Now, what was my experience with this specific product: a) I didn't hear the creaking sound again for almost two weeks after applying it, I assume it reached areas where the oil couldn't reach with a simple syringe, b) the smell lasted for a maximum of 2 days, while with the oil it lasted for 3 weeks, c) its application was much simpler and d) the quantity and cost were satisfactory for its job. Definitely, either in combination with oil in difficult areas or on its own, it will become my best friend for this job... buy it fearlessly, it does what it promises...
