I don’t usually write reviews but I HAD TO FOR THIS.I have tried everything — every brand of ant bait/trap, sprays, coffee grounds and other herbal remedies, plug-in sound emitting repellants — and still, every spring and summer my apartment becomes INFESTED with ants..I’m talking lines of ants, hundreds to thousands, in every room of my home, on the floors, countertops, all over my trash cans, etc. for months despite me keeping an extremely clean and sanitary home. I bought these out of desperation and I’m so glad I did.From day 1 to day 3 of using these, I went from the beginning of an infestation to 3-4 random ants in my whole apartment. As I write this on day 4, I haven’t seen a single ant. I’m SO RELIEVED.Cons — EXTREMELY potent. It smells like a citronella-forward herbal natural ant spray imo, and it’s an almost overpowering smell, however this could be because I put 5 individual packs throughout my 550sq ft apartment (1 at each place they tend to enter from)Also a little bit pricey compared to other at home solutions HOWEVER I’ll continue to buy these repellants happily because they actually work!Pros—WAY less messy than constantly spraying ant spray, less messy than liquid ant baits and less of a hassle to set up. Less toxic than most other remedies. My dog is not interested in the pack at all and won’t mess with it (I can’t speak for all dogs though so keep that in mind when placing these repellants). Prevents ants from entering your home rather than you trying to get rid of them once they have arrived. These are actually effective!!!Im really glad these exist and I hope they work just as well for you!!
