5*. Fast delivery nd excellent products

Susan-Edinburgh-5 Stars

Honestly from start to finish, the process has been a breeze because of the information provided by this company and the fast delivery service offered. I am based in Scotland and really didn't expect the delivery to be next day but it did come and the powder has instructions on the bottle. I know that whenever a fly lands on the powder, it will soon be dead!

Julia-Winchester-5 Stars

Many many thanks for the service. Will use again if I need to

Harriet-Gloucester-5 Stars

10/10. I was a little overwhelmed when looking at all of the different products but the advice line assisted and gave very clear and helpful advice which has worked a treat

Robert-Essex-5 Stars

Can't believe how effective this product is. I only applied this a few days ago and since then we have seen no flies in the main part of the house. Many thanks to this company for making a stressful situation easier.

Vanessa-Oxford-5 Stars

Cheap and fast-acting alternative to constant fumigation. I have paid a fortune for different pest control companies to fumigate the area but it never lasts.

Felix-Suffolk-5 Stars

Brilliant product for sprinkling on the beams in a loft. I've been told it stays effective for 10 weeks too!

John-Eastbourne-5 Stars

Provided fast knock-down of all flies in the loft. Very happy customer

Concorde delivery from USA to UK

Thank you for processing my order swiftly. It was delivered nearly as fast as our local parcels! I wont be using the lawn insecticide just yet as I bought it to combat some cluster flies that I believe are in the lawn around our holiday caravan. Best used early spring I'm told. Funny though that the only items I found were from America. I wonder if THEY don't like us using it here. Thank you once again for a swift despatch. Patrick Morgan

haven't had a chance to use the product yet but very pleased with how quick it came after ordering.

Ineke-Bromsgrove (Worcs)-5 Stars

Delivery was next day - as promised. I had to have the parcel delivered to a neighbour as I wasn't at home and we both received texts giving us a delivery slot - which was spot on. Well done! I certainly recommend this firm. Clusterflies all gone for now. I'll just have to wait and see if they return.

Efficient delivery.

The Pest Expert P+ XL fogger deals with our cluster fly problem. Each Sept/Oct we get an infestation (hundreds) of cluster flies in our loft. Its a 5 bedroom house so a large loft. One XL size fogger gets 'em all. I put the lights on to attract them to the middle of the loft, set off a fogger then go up the next day with the hoover. I think the product could be a little cheaper (particularly when buying in bulk as I have just done), but don't quibble because it does exactly what it says on the tin!

faultless service in its entirety
