I used to by Amiral Spidergone spray which was brilliant. Could spray the door frames and corners and nothing would cross or would die in the process. I guess it was too toxic as can’t find it to buy now! That stuff was just fab.
Lots of spider sprays on Amazon, but I’m looking for one that remains active on surfaces to deter/kill spiders.
Im not looking at the merits of not killing spiders. We have a false widow Infestation outside and they are starting to get nearer the windows and come in.
Also insect foggers/spider bombs? Thinking if we can clear the garage a bit of where they live less likely to invade the house
