Best Way to Measure and Mix Permethrin Insecticide Safely?
Asked by CuriousBee42
I'm trying to mix 1.6 fluid ounces of 38% Permethrin insecticide with a gallon of water. The instructions specify to achieve a 0.5% emulsion but repeatedly emphasize not to use any eating or cooking utensils. I plan to fill a gallon milk jug with water for measurement, but I'm looking for the safest method to accurately measure the Permethrin for my application against stubborn carpenter bees. Any tips?

Honestly, it's best to just buy some inexpensive measuring tools and keep them in the garage just for chemical use. Makes everything much simpler!

When they say not to use cooking utensils, they mean don’t mix chemicals with things you use for food. Dedicated tools are fine, but I’d avoid using a milk jug for mixing just to be safe. Stick with something disposable or specifically for chemicals.

Even tools from the dollar store can work! Just get some measuring spoons and keep them in your shed for this kind of task.

You could use an old Nyquil cap to measure the Permethrin. It's disposable, so you can just toss it away when you're done. Make sure to rinse it out if needed, but it’s an easy solution!

If you want to be extra cautious, buy a dedicated measuring device and label it "POISON" with a Sharpie. Just avoid using it for anything else after mixing your chemicals. It's all about safety!

Consider grabbing some small disposable cups, like the Dixie style ones. Use a measuring device to get your 1.6 oz of water, pour it into the cup, mark the level with a pen, then empty it and fill it with Permethrin up to the mark. It's a simple and effective method!

You might also want to use a disposable syringe (without a needle) or a disposable measuring cup. They work great for accurate measurements!

BeeKeeperMike: Just a heads up, make sure that any cap or container you use is completely dry before throwing it away. Better safe than sorry!
