Bayer Coopex Residual Insecticide

This is the only "safe" insecticide to use for ants and spiders – We have got aviaries - and you can't spray just anything to control ants and spiders. Coopex is the only effective product that won't kill birds. (However, it is deadly for amphibians such as frogs - so one must be careful.) You can see Coopex working within 30 seconds of spraying it when it is dropping ants and spiders. And the product will last months, thereby preventing re-infestation. For people considering using it - Coopex is actually a powder that is dispersed with water by spraying it in a sprayer. The water dries off, leaving a very fine powder. This why it is residual and keeps working. However, rain will wash it off. It is not a chemical like Mortein that evaporates over time.

Kills everything indoors and outdoors for months – Works really well on cockroaches, spiders and other bugs for months outdoors. Just mix the powder in 2.5-5L of water, shake well and spray to create a barrier. Bugs will drop dead overnight and over next following weeks. Spider webs won't come back for months. This is the only spray that lasts as it says on the label. The only downside is that it leaves a slight white powdery residue, but that shows that it's still there and working. This residue can easily be rinsed away with water. So far no resistance but I might rotate pesticides to avoid it. No weird smell either but always wear PPE.

Great Product – I have been using Cooper for 20 years and it is the best we spray outside our house around windows ect for spiders you can even spray trees that have webs going to you house its amazing product

Worked well. Inexpensive – Easy to mix and use in a small sprayer. Apparently safe to use both inside and outside the house. Probably the best ant killer sold to the public in my opinion.

THIS STUFF WORKS – I used to have so many bugs on my out side wall , I used other insecticides and they never worked like chemspray .I got this 25g-coopex-insecticide-sachet ,Put whole packet in 5 liter spray , soak out side walls and pavers , next day all bugs dead on ground and now 4 months later no bugs - highly recommend . Do spray if its sunny or really hot . but I think its a time for a booster shot now . best yet only payed about $12
