Problem with meal moths at home?

I talked to my friend and I told her that we have a problem with insects at home.I said that we don't know what's the best thing to do to eliminate those pests.She gave me an advice if ever here in our home we experienced being infested with indian meal moth for they went through with this situation too.She told me that they used Indian meal moth traps since it's easy to use,pesticide free and it really works.She told me that now,they are sure that their foods in pantry are safe from meal moths.I just told her that I'll certainly look the product she told me.
