Hi. Yes, I have been seeing dotted / mottled tineid moths on tineola bisselliella pheromone strips this year in different parts of London. England.
I have had at least two different species, quite distinct from each other but both look like tineids to me. Like yours, these are found in rooms near to the exterior and generally where there are trees nearby, often with open windows. I haven't yet confirmed whether the smaller speckled moths are *Niditinea fuscella *or another similar looking species and I don't yet know what the slightly larger speckled moths with more defined speckles and striped antennae are as the tineid family is huge. Part of the delay in ID is the poor quality of the samples as they're caught in trap glue. It's obvious that they are neither Tineola bisselliella nor Monopis sp. I found just a few last year and a slightly larger number this summer in different areas of London. Rather like Monopis, I think we will need to monitor over time to understand whether these are a threat to our collections or simply lost wanderers.
