Keeps bloodsuckers away from your pet! The Stichfrei Animal Spray from Ballistol protects your animal friends for up to 8 hours against mosquitoes (including black flies), horseflies, ticks and grass mites. This can also prevent summer eczema, for example, which is triggered by the "bite" of the black fly. A pleasantly scented alternative to aggressive chemical agents. Note: Use biocidal products carefully. Always read the label and product information before use.
