Bought to rid house of its many spiders - the large house ones and a lot of varying sizes around the conservatory. Applied it with a paintbrush around the skirting boards in most rooms 3 weeks ago - the floors are wooden - both hardwood and pine. I have not seen a live spider since - one or 2 dead ones only - which made me wonder if it had worked but evidence of spider activity is gone. No more cobwebs in corners. When I hoover with the Dyson dust detector, no more long spider webs which always told me where they were hiding. It even smells pleasant though I try not to breathe it in too much. Not spraying, but 'painting' it on helps. I'm so relieved and grateful to Pest Expert for this product.
