Pest Expert Formula 'C' Carpet Moth Spray is our best-selling product for eradicating carpet moth infestations and the most powerful carpet moth spray available to the amateur market. Formula 'C' is a fast-acting carpet moth killer that enables you to carry out an effective carpet moth treatment to carpets and rugs, with a long-lasting residual that maintains carpet moth control for up to 12 weeks.
Pest Expert Formula 'C' is a highly-effective carpet moth spray that offers both rapid and prolonged carpet moth control. As well as delivering a quick knockdown it also leaves an insecticidal residue that continues to kill for up to 12 weeks.
Formula 'C' is safe for direct application to rugs and carpets as it is water-based so will not cause them any damage.
Formula 'C' is low-odour and free from solvents, so it is perfectly suitable for use in homes with children and/or pets, provided they are kept out of the area being treated until all surfaces are dry (2-3 hours).
The active ingredient in Formula 'C' is the powerful broad spectrum insecticide cypermethrin (0.1% w/w), which is also effective against a wide range of flying and crawling insects.
Each 1L trigger-spray is sufficient to treat an area of up to 25m2 and one application should be enough for a successful carpet moth treatment. However, to eradicate a particularly heavy carpet moth infestation then a second application may be required.
Directions for use
Lightly spray the carpet with Formula 'C', applying more spray to damaged areas. As carpet moths favour dark places, moth eggs and larvae are most often found around the edges of a room and beneath heavy or long-standing furniture, so administer a heavier application of insecticide to these areas. Leave the room for at least 2-3 hours to allow the carpet to dry. Avoid cleaning the treated areas for as long as possible as vacuuming will remove the protective residue.
For a more comprehensive treatment, applying Formula 'P' Carpet Moth Powder and fumigating the room using our Pest Expert Formula 'P' Foggers will eradicate adult moths. Moth traps are also an excellent method of monitoring activity after treatment.
As carpet moths are textile pests they will also feed on clothing containing natural fibres, so if the affected carpet is in a bedroom, then you may wish to consider adding moth control products to protect your wardrobes, such as Rentokil Moth Killer Cassettes and/or Moth Proof Garment Bags.
