I couldn’t see it at all on the white glossed surfaces or the white uPVC window and door frames where it was translucent, dry and non-sticky. It is very effective and is a product that can be used indoors or out and can be sprayed around the perimeter of your house where woodlice are active.Pyrethrum 5EC is approved for use against a wide range of pests including Spotted Winged Drosophila (SWD), greenfly, whitefly, blackfly, thrips, flea beetle, aphids and caterpillars. Once sprayed, Dethlacdries to a hard clear film, which remains fully effective for months, even when it rains or if the surface is washed with detergents. It did leave a slight sheen on my plasterboarded walls which were painted with matt emulsion and were very absorbent – but it was barely noticeable and only from an angle. As you can see from my photos below, they certainly are effective and I still have two in my wardrobe to protect my clothes.

Spiderex can be used outdoors, but I was able to scrub it off timber and plastic with a sponge, so I believe it will need to be reapplied more frequently if it’s sprayed onto a surface that’s subjected to a lot of rain. To deal with this start by stripping back the garden, remove dense shrubs and plants around your home.

I followed Spiderex’s instructions, kept the can 30cm from the surface, and released the product in one-second bursts.
