Using insecticide is the most common way of controlling these moths. This involves using chemical compounds of various kinds but delivered in different ways. For example: a fogging spray to kill the flying moths. A water based insecticide spray to kill the larvae – both contain the same type of insecticide, but are delivered in different ways. One with tiny airborne particles and the other mixed with the water.
A professional pest controller has access to some more potent and longer lasting versions of these chemical pesticides.
Treatment of a house or flat using these insecticides relies on the insect, as a larvae or adult, coming into contact with the toxic element of the compound in a high enough concentration to kill it. So for a chemical treatment to be most effective the insecticide needs to be sprayed, pumped or blown in and on as much of the property as is practically possible. If the treatment coincides with a fitted carpet being replaced then access is made possible to the floorboards and under the floor – this will make a treatment more successful, not only because insecticide can be deployed under the floorboards, but it also gives a chance to get rid of all the eggs and moth debris that will be under the carpet. However, excellent levels of control are still achievable with insecticide without removing a fitted carpet.
