Using insecticide is the most common way of controlling moths. This involves using chemical compounds of various kinds but delivered in different ways. For example: a fogging spray, or fumigation, 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.
Examples of these products are readily available to the non-professional, but professional pest controllers have 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 practical and safely 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 products can be deployed under the floorboards where there are gaps and holes, 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.
All the products we use are HSE approved for use in a domestic environment. We use products according to the statutory regulations and within the best practice guidelines of CoSHH (Control of Substances Hazardous to Health). Therefore, once carpets are dry, they are safe to be used by people and pets.
However, if you prefer not to proceed with a chemical treatment, there are alternative ways of treating moth infestations using heat treatment.
