Product Information

I did find that it was more visible on the brown uPVC and timber door and window frames, where it left a slight sheen, but as part of my test, I wanted to see if the sheen was permanent, so I scrubbed it with a sponge and water – the product washed off but only after some scrubbing and it didn’t leave any persisting marks on the plastic or timber. Once sprayed, Dethlac dries to a hard clear film, which remains fully effective for months, even when it rains (for ants in the garden) or if the surface is washed with detergents (for ants in the kitchen and around the home). Dethlac can be used indoors and outdoors and may be applied on any firm non-absorbent surface, ie doors, window frames (not upvc), skirting boards, shelves, concrete & patios etc. The design makes it easy to apply, taking the hassle out of using at-home treatments to fix an ant problem. It’s a good liquid alternative to using bait stations and granular bait without having to use an aerosol ant killer spray.

The aerosol should be disposed of in a safe way, the same way as you would dispose any other aerosol. 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. It’s not 100% waterproof, but it did not wash off with just a splash of water; I had to scrub it with reasonable effort to get it off. I would describe Spiderex as water-resistant.

I’m 100% sure Spiderex is effective and I noticed a drop in the number of spider incursions, but I was very thorough in treating the entrance points; I even sprayed around cable and pipes that entered the property and the insides of all the window and door frames. I sniffed the product one week after it dried from a distance of 50cm, and I couldn’t smell it, so I’m confident it won’t leave any noticeable odours.

When to Apply Ant Killer I recommend Spiderex to anyone who wants to keep spiders out of their home, shed, garage or caravan but I suggest doing a test on a patch area first and being careful around absorbent surfaces such as plastered walls.It is perfectly safe once the spray is dry, which is normally within a few minutes. However, we would recommend that children and pets are kept away whilst spraying.
