Internal alarm sensor

[Jewellbags]

As on a previous post our alarm went off the other evening when we were out . No door interference or anything untoward but where we are they have some large bugs everywhere (look like mini rhinos).

Big enough to set off the internal sensor so you think ?

I would suspect a slightly open drive/passenger window left slightly open ----that would have let them in ???
