Cluster Fly Killer Smoke Bomb & Fumer Kit (Pack of 4)

Effectively eliminate large cluster fly infestations with our Smoke Bomb & Fumer Kit. Cluster flies hibernate in large numbers in roof voids and attics over winter. These smoke bombs are the most effective solution for this problem, releasing a fine insecticidal smoke that fills the entire space, penetrating all cracks and crevices to kill the flies. This pack of four fumers is perfect for treating larger lofts or for repeat treatments to control persistent infestations year after year.
