Instructions: Spray the entire engine compartment well, especially cables and hoses. In the event of problems on surfaces e.g. barns or attics, try to find the entry holes/loopholes and spray them with a powerful spray (approx. 10 times per metre walking by) thoroughly from inside and outside. Shake can before use. The spray lasts about 3 - 4 weeks, repeat the process accordingly.
Caution: use biocides safely. Always read the label and product information before use.
