Critterkill Discount Codes Black Friday 2026 - 15% OFF

Critterkill is a UK retailer based in Exeter that sells professional-strength DIY pest control products for use around the home. The range covers insecticide sprays, smoke bombs, insect foggers and bed bug killer sprays, and is aimed at pests including bed bugs, fleas, moths, cockroaches and spiders. Everything is non-staining, odourless and water-based, so the products can be used in many parts of the home, mattresses and carpets included, once they have dried. The aim is safe, effective solutions that householders find straightforward to apply themselves, for people who want professional-grade products without hiring a contractor.

Pest control services are offered as well as the shop, and that work comes with a guarantee. If pests come back within a set period after a treatment, the team takes another look at the problem and carries out further treatments where needed so the customer is satisfied. How quickly pests are dealt with depends on how heavy the infestation is and which pest is involved, and the experienced technicians give an estimated timeline at the initial consultation.

Payment can be made by Visa, Mastercard or PayPal. There is a free 30-day window for returns, as long as items come back undamaged and unused, with their original packaging, in a resaleable condition, and refunds are paid to the original payment method. Exchanges are available when a product is defective or incorrect, and faulty items are covered for 14 days.

Shoppers can also join the Rewards Club, a loyalty scheme that earns points automatically on purchases, which can then be put toward the cost of later orders. Staff of FW3 Group Limited receive an employee discount on pest control products, with eligibility confirmed through employment with the company.

Codes go into the discount code box at the Critterkill checkout; deals need no code.

Critterkill accepts Visa, Mastercard and PayPal.
