## Description

Pest Expert Formula 'C+' Flea Spray is a fast-acting flea killer that enables you to carry out an effective flea treatment against dog and cat fleas in the home, with a long-lasting residual that helps maintain flea control. Formula 'C+' is the most powerful insecticidal flea spray available to the amateur market. As well as being a fast-acting flea treatment, Formula 'C+' also offers long-lasting flea control as the protective residue it leaves behind continues to kill for up to 12 weeks after application. Formula 'C+' is effective against both dog and cat fleas and, being a water-based insecticide, it is safe for direct application to rugs and carpets. Formula 'C' is virtually odourless and contains no solvents, so it is perfectly suitable for use in households where there are children and/or pets, as long as they are kept out of the area being treated until all surfaces are dry (approx 2-3 hours). Once applied, do not vacuum for as long as you can. Our latest innovative formulation incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that halts the progression of the lifecycle development from juvenile to adult, resulting in the inability for the flea to reproduce. The second is the addition of chrysanthemum cinerariaefolium extract, a natural pyrethrum, which when combined with cypermethrin (0.1%) has a synergistic effect, helping to deliver an even faster knockdown and longer-lasting residual for ongoing control of all lifecycle stages. One application should be sufficient for a successful treatment, although a second application may be necessary if the flea infestation is particularly heavy or flea eggs are deeply entrenched.

Review: Superb - Excellent. Tried lots of other treatments but this was the only one that's been effective and lasted 6 months.
Review: Fairly good, - It didn't work completely but it at least cut the quantity of the problem down.

*by H***R on 18 September 2023*

I been abroad and came back home to my mum panicking and stressed that she was getting numerous of fleas jumping on her legs and ankles the kittens and mother cat completely covered, she was uncomfortable telling me I told her something like this should be dealt with as soon as you notice any, but its all okay and under control with this product. I was walking up my carpet stairs having half a dozen of fleas on my ankles each time after spraying a decent amount so the floor is damp of the solution worked very quick they were still alive but slow for first few hours next day till not see a single alive adult flea actually saw dead ones on the non carpet floors and sofas. Those that say dont work must not be doing something right as my family home is a five bedroom and was full of them and killed all adults. First i vacuumed the floor this vibration triggers them to come up to the top of the carpet also takes some eggs and cycle out of carpet or flooring too then made sure nothing was on the floor or furniture. Then sprayed enough so everything was damp the two leather sofas the floors, bed mattresses and around the bed left the rooms or treated areas for few hours, i would say the smell is okay after 2/3 hours but the mattresses and soft or silk or leather furniture takes 4-5 hours to dry thats how you know you put enough on the areas. My important tip with using this is its so important to damp the area with this product anywhere the fleas can jump onto hence why i did sofas and beds ; ( just wash the bedding stuff in washing machine) along with the flooring if you have carpet put more on carpers than on any type of flooring as i noticed in my home I wasn’t getting many on me downstairs where we don’t have carpet. Even though I’ve done all this and worked killing first generation its also important that you don’t clean the floors or where ever you sprayed for 4/5 days then u can vacuum, clean up treated areas again and do a second house coating like the first i advise all to do a second coating as fleas have complicated life cycle and there will be eggs that hatch from first adult generation. For those that have heavy first generation I would recommend a third house coating minimum as thats what im doing in my room just to be on safe side. Please pleas please there is no point treating your house and not your cat or other way around it will not solve the flea problem at all it will never end. I gave my cat that isnt nursing a johnsons flea tablet i crushed it in smaller pieces as she dnt eat in full and within 24 hrs shes clear from adult fleas i give her the tablet the same day im treating the house i find this works better along with fixing the infestation. For my nursing mother cat i did the same my kittens are 4 weeks old her having this tablet does not affect them but they are too young to have one themselves so i gave them a bathe with kitten/ puppy shampoo i order it on amazon too it’s literally called that and does the job no side effects to them, gave them a comb and all good. I bath them same say treating house too. Final thing I’m going to say for any that may have this concern as i did myself if worried about having to take out cats of house as the house is treated. As i have 5 kittens, the mother and another 5 month old kitten it was bit much for me to take them all out so i would choose the biggest room for them to stay in shut the door and thats their safe place away from the smell the stuff doesn’t smell that real strong so that strategy works fine. Then after treated dried thats when i would give them their flea tablet put mother cat and 5 month old cat in a treated room with clean washed beds and stuff then give each kitten bath and comb through. Put with the mother then shut their door to treat the final room. This product covered my five bedroom house but after that will need another but is 100% worth it. I start round two spraying tomorrow, I recommend this to anyone dealing with this and is okay with this budget £70-£80. I understand that is still quite a bit to pay out but if you’re worried its not going to work but just about have enough… it does work as i worry and in same boat of thoughts and situation with not having loads to spend out and trusted the product did the routine that is important and couldn’t be happier with the results for the price. All the best for those dealing with this, I know that its a bloody nightmare.
