Product Information
Pest Expert Formula 'C' is a highly-effective carpet moth killer 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 5Ltr container is sufficient to treat an area of up to 125m2 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.

When carrying out a treatment to a large area, we recommend using one of our Pressure Sprayers to enable an even distribution of the Formula 'C' insecticide and help you achieve a professional application (see Related Products below).

For a more comprehensive treatment, applying Formula 'P' Carpet Moth Powder and fumigating the room using our Formula 'P' Moth Killing 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.

For the best value for money please see our Carpet Moth Treatment Kits, which contain a combination of our best carpet moth products.

Reviewer: Jennifer from London   5 Stars

Having quite a large house, we opted for the large container of Formula C. We applied it throughout the ground floor of the house and I am confident the moth problem has been solved!

Reviewer: John T from Sheffield   5 Stars

Formula C is a fantastic insecticide, I used it at 4 week intervals and (fingers crossed) there have been no moths seen since! Would recommend to anyone with a moth issue!

Reviewer: Jose from Darlington   5 Stars

Happy with the carpet spray! Killed the moths and grubs and we've not seen any signs for a while now!

Reviewer: Mike John from Lincoln   5 Stars

service was 1st class

The tracking of the delivery was excellent - I could follow the driver on his round leading to my home. This was the day after I ordered. I have unfortunately had to use the formula C insecticide before, a year ago, and I know it works. Now I have learnt you need to remain vigilant for reoccurrences and have bought a larger more economical quantity. Looks good so far.

Great service again !

We began using Pest Expert to deal with carpet moths after a national company charged a lot of money and failed to sort the problem. We are still very happy moth free customers , and continue to be impressed by fair prices , useful information and fast dispatch.
