We've just discovered a meal moth larvae infestation, we don't know how long it's been there, as it's in a rarely accessed part of a large room. The infestation seems fairly large, and there seems to be larvae right in the carpet, are these merely the shells, or hibernating cocoons of the larvae. Will we have to replace the carpet? We presume the infestation is in the Chinchilla (rodent) food very near to where we located the larvae. This is really distressing, and we're not entirely sure of what to do, the larvae seem to keep appearing. We've only noticed this within the last hour, some advice would be invaluable. Currently, we're trying to steam them out of the carpet with an iron, will this have any effect?
