Okay, turn the hypothetical around. Let’s say you (generic “you”) had an insurance policy that covered you for loss caused by insect and vermin infestations, and the insurance company refused to pay after a spider infestation. Would you stoically accept the insurance company’s position? Maybe you would wouldn’t even file a claim in the first place, to demonstrate a commitment to scientifically precise language in insurance policies.
Perhaps. I suspect many of us would reasonably argue, in such a situation, that the category of loss described in the policy is obvious to a reasonable observer, and if, say, an ant infestation is valid grounds for a claim, a spider infestation should be too.
I’m no great fan of the insurance industry, but putting that aside for a moment, it does seem that in terms of the contract language, a sensible conclusion was reached here.
