I feel your pain. I'm terrified. So much so (and I'd love to say I'm joking here but I'm not ) when my marriage was going through a really bad period, it's one of the factors that made me think twice about splitting up: the fact I'd be dealing with spiders on my own! (Luckily we're in a good place now me and DH)
Also, now and again (he's older) I think of things like how I'd deal with clearing the loft out/garage if he died 🙈😯 and the thought makes me panic (because of encountering large spiders )
I'm really horribly phobic.
I've joined a spider group on Facebook and it does help a little (I've gained more knowledge and people talk in positive language about spiders and it does kind of psychologically help with reconditioning ) I'm also now ok with them outside. And can leave small and medium ones indoors mostly alone.
I've identified two types I am petrified of : GHS (giant house spiders) and segestria Florentina. Those ones trigger a full blown phobia response.
I dread every September and late August (looks like we're there now 😬) because it's spider season. I don't even know how people do the paper/glass thing. There's no chance I'd get that close.
Nothing particularly works to deter. I have bought lemon diffusers and stuck them round the house as apparently they are repelled by citrus. But ... I'm not holding out too much hope
Keep windows closed if able. (Females are already resident in your home if they're there - it's the males that come in , looking for the females)
Cellar spiders (spindley ones) are great to keep and let breed : they will attack and kill the biggies believe it or not. Luckily we've got loads of them. I never kill them.
Indorex spray is meant to work. But people on here will disapprove as technically it's cruel. I've never dared try it as I have children and my son had asthma when young.
