White-shouldered house moths from new furniture
I have a feeling that I will be in for a losing battle with a local furniture store. About a month ago, they delivered an upholstered sofa, matching loveseat, and a leather sectional sofa. These items had been in their warehouse for about three months waiting for my remodel to be completed. The sofa and loveseat went into one room and the leather section went into another. The room with the sofa/loveseat has a sliding door that completely separates it from the room where the leather sectional is.
About a week after the furniture was delivered, I noticed a couple of moths in the house, in the 'sectional' room. Assumed it had flown in through a door left open during moving-in, killed it, and thought nothing more of it. A day or so later I saw another moth, assumed the same, etc.
Over the next two weeks I found anywhere from two to four moths almost every other day. They were most often in the room where the sofa/loveseat is, but occasionaly in the other room as well. I began to suspect that the moths were coming from the furniture, so I deliberately left the door to that room closed all the time to "seal it off". Sure enough, even though the room was completely isolated from the rest of the house and also from the outdoors, new moths have continued to appear every few days and are still doing so.
I am very concerned about the presence of these moths because there is wool carpeting in several rooms upstairs and also in the room where the sectional is. The carpeting went down about a week before the furniture came in. At first I thought the moths might be coming from the carpeting, but in that case they would not be appearing in the sealed-off room, which has a porcelain tile floor. The only thing those two rooms have in common is the presence of the furniture received in that delivery.
I've contacted the store with no results. They claim that there is no "proof" that the furniture they delivered is moth-infested. Short of litterally slicing the furniture apart to determine this, I have no idea how to go about dealing with the situation. These particular moths (white-shouldered house moth) are common in warehouses and I am sure that is where the furniture picked them up, as they were from two entirely different manufacturers. I would not want to have to saturate the furniture with insecticide in order to kill the moths; I'd rather replace the furniture than do that. But I don't think that the replacement should be entirely at my own expense; and I'm nervous now about the possibility of the moths having already laid eggs in my new wool carpet! I've read that the female of this moth can lay up to 500 eggs under optimal conditions! That's pretty scary.
I'm interested in any opinions on whether I am justified in asking for either replacement pieces or some sort of refund to compensate for the expense of disposing of and replacing these items. The store doesn't agree, of course. Am I in an impossible unprovable situation?
