I'm starting to wonder Ambrose! I have a feeling they hide out in the cobbly pebbles that are all around the foot of the house and then come out at night. They don't tend to come inside except on rare occasion but it is a bit revolting when they do. We put greenie-friendly pellets down in the veg patch in the garden and there were dozens dead the next morning, but it doesn't seem to stop them from assaulting the house each night - it's like the normandy landings in vertical form.
I always wondered if beer traps were just inviting them from far and wide, rather than just getting ones that are near. I've heard cold coffee works a treat as concentrated stuff kills them and less concentrated puts them off but I've no idea if it's true. Maybe salt disolved into water and sprinkled all round the pebbles? Hopefully not unkind enough to fizz them all but might send them running for another house and leave an unpleasant taste on the rocks for a while?
I looked at the copper strip but I'd need about 8 rolls to stop them, might do it in the end though.
Don't want to seal up air bricks, but at the same time don't want them rumbling round in the walls!
Count how many there are, then put a small mark on 20% of them. bit of tippex or something, then have a look a week later, and see how many have tippex on them, this will give you a sense of how many are 'yours' and how many ae new.
I'm a lover of science, however I'm failing to see the point of this, do you mean to identify if they're passing through or resident? And what's the options with each outcome, or are we just curious? Not sure tippex sticks to nuclear-slime-mankiness
How quick are the slugs in your house ?
