Formula C+ Cluster Fly Killer Spray with Insect Growth Regulator, Non-Stain

Been spray this all over the window past 24 hours now, im finally seeing less cluster flies, I wish I saw this as soon as they came As I was dealing with this problem for two weeks, best product out there, dont bother was your time buying fly spray does not work. AMAZING PRODUCT. I would not over spray as the flume can get abit too much, as I had to quickly open a window.

Amazing product that really works!

Very good 👍👏

We had a plague of cluster flies in the house this winter; first one, then two and suddenly twenty a day and they drove us nuts. I sprayed the outside window and door surrounds twice over the period of three weeks and all the flies gradually all disappeared. Highly recommend this product.

I rarely write reviews, but for this product I had to. I was having serious problems with fruit flies in my restaurant. I used three cans of Raid at once and they didn’t die, but with this product they all died within minutes. Amazing — highly recommended.

I but this stuff every summer for my bin area. Just spray it in & around my bins to help prevent maggots & flies. If it rains just respray the area. It’s really good at killing maggots if they do appear. I can’t help how hot my garden gets but this does work. Be careful though, it does kill other insects including bees & butterflies.

Seemed to have worked well so far, will buy again

I had an infestation of cluster flies in three rooms. A few annoying flies one humid day suddenly became an alarming plague. This stuff works to devasting effect. It completely destroyed them in a couple of days. If you have a problem with cluster flies, do not despair, this stuff will obliterate them. Apply it well tound your window frames and any cracks they might be slipping in, and they will be gone in no time.
