Pest Expert Formula 'C+' Carpet Moth Spray 5Ltr

Our Price: £31.95 inc. VAT
Our Price: £26.63 excl. VAT

Pest Expert Formula 'C+' Advanced is the new and improved formulation of our best-selling moth killer spray. With the addition of two powerful active ingredients, this triple action carpet moth killer spray is fastest and most effective carpet moth spray available to the amateur market. It is a fast-acting carpet moth killer that is safe to use on carpets and rugs. The insecticide in the spray kills carpet moths on contact, leaving a protective residue that lasts for up to 12 weeks after use to offer long lasting carpet moth control.  

Until December 2012, the full Pest Expert range was only available to the professional market; however, as Pest Expert Formula 'C+' is now available for amateur use, we have decided to replace the previously sold Formula C with this fantastic product.

Formula ‘C+’ Advanced is a carpet moth spray that has a water-based solution, meaning it is completely safe to use on textile and furnishings that aren’t susceptible to water damage. This also makes it low-odour and solvent-free so your furniture and carpets will be unaffected by the treatment.

Formula 'C+' Advanced now contains three active ingredients: the first being pyriproxyfen, a ground-breaking insect growth regulator that halts the progression of the carpet moth’s life-cycle, from juvenile to adult, resulting in the moths not being able to reproduce therefore ensuring there is no increase in new moths numbers. The second is chrysanthemum cinerariaefolium extract, a 100% natural pyrethrum, which when combined with the third active, Cypermethrin, has a synergistic effect which helps to deliver an even quicker knockdown, more powerful and longer-lasting residual to maintain ongoing control of all life stages of the moth.

This 5Ltr Formula 'C+' Advanced Carpet Moth Spray will typically provide effective coverage to an area of around 250 sq mtrs in a single application! This is double the area covered by cheap soluble sachets offered elsewhere, thus providing better value for money and avoiding the fuss of having to re-treat. Heavy carpet moth infestations may require a second treatment.

A carpet moth treatment with the Formula ‘C+’ Advanced spray is simple – just apply the spray to the carpets, furnishings and other affected areas of the room, paying more attention to the edges and corners where eggs and larvae may be hidden from sight. Leave for 3-4 hours for the spray to dry then try and avoid vacuuming for as long as possible to allow the residue to have the greatest effect.

Alternatively, please see our Carpet Moth Killer Kits which contain Formula 'C+' Advanced Carpet Moth Spray as well as Formula 'P' Carpet Moth Powder, Formula 'P' Foggersand Demi Diamond Moth TrapsAll our Kits are supplied with step-by-step instructions and offer excellent value for money.

Roger-Ashford-5 Stars

After doing much research regarding the best product and method to use to rid myself of moths in my woolen carpet, I decided to take a chance and buy Pest Control C. It was £40 plus and I thought this was rather expensive as I used the full 5 litres in one application. This was a week ago, and I only did round the edges, but haven't seen any new activity yet, so hopefully it has worked, allbeit a bit early to tell yet. They recommend a further treatment after 12 weeks, so looks as if I'll have to cough up another 40 odd quid.

Helen Fleet-Oxford-5 Stars

Liz-Gressenhall-5 Stars

We were horrified to find damage to our carpets was caused by moths and could not believe, having had wool carpets for 45 years that we had not experienced this before but luckily computer and 'Mothkiller' to the rescue. Spray and items ordered arrived next day. That was only the easy bit, next carpets removed from gripper rail and all heavy furniture emptied and moved. Job done after a insurance does not cover insect damage !. We are now eagle eyed to spot for further infection !

Roger-Bicester-5 Stars
