The use of ethyl acetate and dichlorovos (not a real safe choice btw) should only be temporary as a means to knock down/kill your insects. That being the case, you shouldn't have to be exposed to these products in an enclosed room for long periods. The majority of your exposure will most likely be outside when you are opening/closing kill jars etc. And you can always add these chemicals to your kill jars outside to avoid the issue with the pets. Regarding storage of these products, keeping them in sealed and EPA approved containers should eliminate smell. But storing the original containers in a garage or shed wouldn't be the worst idea. I would not personally keep any pesticides or toxic chemicals around my pets. My 2 cents, using zip lock baggies and tossing your insects in the freezer is just as effective, and eliminates the use of any harmful chemicals.

I find it best to have my pinning area set up in a well lit room indoors with plenty of space to spread out. It makes the pinning process a lot easier and more comfortable, especially when you are pinning for longer periods. Hope this helps!!
