Spider dead but back tomorrow

The common spider tolerate that stuff really is not good and is a timely basis. The long-term effect described is, however, little exists. The very next day the next grins a spider at the same place again. While it may be a little less, than without treatment, but I expected more.

I have used the product in the converted basement (guest rooms, hall, toilet). Noteworthy positive is the fact that really remain any stains on light-colored walls.

If the 2l are all, I will try another product.
