Pest Expert Formula C+ Advanced Carpet Moth Killer Spray is the new and improved formulation of our bestselling original product, Formula C. Formula C+ Advanced is a ready-to-use triple action carpet moth killer, with a long-lasting residual that maintains carpet moth control for up to 12 weeks. Its unique combination of actives make it the most powerful carpet moth spray available to the amateur market, and the ultimate insecticide for anyone wanting fast and effective eradication of any size carpet moth infestation.

  •  Fast-acting: Rapid knockdown
  •  Low-odour: No smell during or after use
  •  Non-staining: Will not damage carpets or rugs
  •  Long-lasting: Residual maintains moth control for up to 12 weeks
  •  Increased coverage: 1L now treats up to 50m2 in a single application

Pest Expert Carpet Moth Spray Product Information

As market leaders, our latest innovative formulation now incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that cleverly works by halting the progression of the carpet moth’s lifecycle development from juvenile to adult, resulting in an inability for the moth to reproduce, and therefore ensuring there is no increase in numbers.

The second is the addition of chrysanthemum cinerariaefolium extract, a natural pyrethrum, which when combined with the existing concentration of cypermethrin has a synergistic effect, helping to deliver an even faster knockdown and longer-lasting residual for ongoing control of all lifecycle stages.

With approval for both professional and amateur use, this professional-grade product can also be used safely in the home. Formula C+ Advanced is easy to use and can be applied directly to rugs and carpets as it is water-based and non-staining, so will not cause any damage.

Formula 'C' is safe for direct application to rugs and carpets as it is water-based so will not cause them any damage.

Each 1L trigger-spray is sufficient to treat an area of up to 50m2 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 Pest Expert 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 control products.

Your products helped us eradicate a widespread problem of carpet moths in our house. The instructions were clear and products easy to use, and prices were reasonable. Have re-ordered several times and order processing and delivery is always quick and accurate. Believe we have eliminated our problem.

Reviewer: Reginald West from Dagenham   5 Stars

these moths were no " TIGER", not easily shot down.

It would appear that the product was successful in disposing of the infestation but I understand carpet Moths can sometimes reappear after 12 mont,hs If they do I will be back for a further supply of the chemicals.

Reviewer: Maria Johnson from Tyne and Wear   5 Stars

Reviewer: Dr john agnew from Rotherham   5 Stars

Appears to be extremely effective but make sure you follow the instructions and shake before use every time.
