Trialpackage. I definitely recommend it because for me this has been helpful. This is not something extraordinary, but I find it quite effective. I did not need a powerful product but at least a product that can help me. I needed because in the yard and in the garden during the summer, there are all kinds of insects. The effectiveness of the product can be seen in the time, you can not get results in an hour, for example. After a few sprayings, the surfaces have more insects. Largely I repels insects, so I'm satisfied, no problems. I also think it has an advantage, that the product does not have an intense smell. Good value for money!
