I swear by Coopex. I use it outside on walls, doors and furniture etc to keep flies away, inside for roaches and it lasts months. I always have 4 spare sachets on hand. I don't use commercial around my house (in or out), except for coopex . Its the only chemical i will never relinquish. Honestly nothing else works as well for as long as coopex.

We were inundated with earwig’s and spiders in and around our house. After using Coopex the earwig’s and spiders instantly disappeared. It’s been 9 months since and still very affective. Can leave a white residue if used on a dark surface, like runs down pergola post, but very easily wiped off!Great product!

Not like it used to be. Some spiders stayed and more arrived. Left a white residue everywhere! Looks aweful.Checked the packet instructions to check my dilution rate.Won't buy again unless they get the formulation correct.Dissappointed.

This is save my life . I bought horse manure to my garden, but it made too much fly from it. And it was really like a nightmare amount of fly in our garden. I tried mulching it and cover poop but not reduce fly amount. And I finally find this product works really amazing!! With in less than hour , massive fly go somewhere or die in some where . I spray on wall window screen garage ,as much as possible fly will touch surface. Unfortunately I got rain next day,but still looks working ok. This product has strong residual where you used. I saw They stay in soil and so on long time and not recommended to plants ,but it will reduce not only fly cockroaches and other insect too. I feel I don’t need call pest control any more. It much cheaper and very easy to use . I see ... MoreThis is save my life . I bought horse manure to my garden, but it made too much fly from it.

It much cheaper and very easy to use . I see also cockroaches die in around house next day.That’s product contains neurotoxic chemicals that disrupt flies' nervous systems, causing quick paralysis and death. The active ingredients, like pyrethroids, target flies' muscles and respiratory functions.
Only thing that works to keep mozzies at bay! Knocks them off by at least 60%! We spray around exterior doors, windows, bricks and eaves around the home and down the fence line either side of our home. Within minutes you can see a difference and it lasts1-3 months depending on rain.
Works extremely well on Ticks. Spray shoes and clothes. Is a surface spray so let it dry. Only thing I found that will kill stink bugs. Also works well on cockroaches and ants.
Sprayed around a month ago, and it hasn't done anything to control ants, spiders or cockroaches. The ants just walked through the spray ay the time - thought it needed to dry first. Nope. Maybe needed more time? Nope, still walking through the residue. Month later, all I have is white residue everywhere and now cockroaches just walking all over the sprayed areas (that are still undercover and have the residue). Yes I made it to spec. No I won't use again.
I use this on my chicken coop to help prevent mites. Works brilliantly.Simply mix in a pressure spray kit (e.g. https://www.bunnings.com.au/aqua-systems-5l-garden-pressure-sprayer-kit_p2960992) and apply to all the crevices, nooks, crannies, corners, etc. inside the chook pen, and then outside and under roof eaves.
House was infested with white cedar moth caterpillars (coming from next door Cape Lilac tree). Tried this and sprayed around bottom of exterior around the whole house and fenceline.Works like a charm! Even cockroaches, crickets and spiders around entrance of doors didn't make it!
Bought it yesterday because I had bed bug issue from traveling for work. Was worrying about getting pest control to come in and having a full deep clean at home.Found this product and got it started ASAP, next day morning it's gotten so much better (85-90%). Altought itill need the second spray down but massive improvement for a very short period of time .
