Found what I think is a male Steatoda Grossa in my flat in Kent, do people agree? A few days later we are finding a lot of smaller spiders (15+) in high corners around the flat, are they its offspring? We are yet to find the female, are there any particular places I should be looking - cold, warm, dark, light? We have young children and want to set all of these spiders free asap!
Indeed Steatoda grossa, they are more widespread than S. nobilis. I'd look around floor level, under furniture & appliances for females. Bear in mind though, that they are quite shy & reclusive, so typically aren't a problem. Spiderlings & wandering males may be more reckless & easily spotted.
So the large one is definitely a male? We are currently packing to move across town on Friday and we're worried that we've packed some! We found the large one in a box that hadn't been opened for quite some time - he fell onto my hand as I was sorting through!
I know it's an almost mpossible situation to predict... but any advice to help avoid bringing them with us to our new house?!
