Does the spray have to be used within a certain amount of time after it's opened?

I do not see any expiration date. I opened a bottle 6 months ago and it seems just as potent. The bottle is pretty air-tight so I do not think it spoils easily.

Not that I'm aware of.. not that it even worked from the beginning though. Seriously, save your money....

I see no reason to be concerned about how long you keep the spray or how fast you use it. Because I spray our bedding daily, my bottle last approximately two months. I did notice that the fine spray works best. That covers more area. I do not see a problem, even if you had it for a longer period of time before using it up. Stringbean

you can spray a little and stop, just press lightly on tab. If you press it all the way down it locks open.

Not after it dries.Strongly suggest testing on small inconspicuous area prior to general use.

yes it would be good after a week. Read the directions and follow the same general guidelines for respraying/treating an area. What ever the time the spray maintains an effectively treatment effect for exterminating the targeted pest would be the same general shelf life of the mixed solution.

The bottle says this, no matter the size: Refrigerate after opening. Best if used within 3 months after opening.

Not while spraying, but I did an hour or so later. No ill effects I could see.

Kinect, Not long. Maybe 1-2 days? And for that reason, you shouldn't mix up more than you intend on using that day. This way you won't foul up your sprayer or end up spraying a finished solution which has deteriorated because the active has sat too long.Cheers,JonathanCustomer CareU-Spray Bugspray

Yes, it's a powder that you mix with water in a sprayer. Apply in the springtime just before the buds open and repeat second application 10 - 12 days after first application. Make sure it is rain free for at least 24 hrs after spraying. WEAR GLOVES.

Yes. Just allow ample time for it to dry before before letting kids or pets around where you sprayed.

No, the spray bottle can not be opened. It is under pressure and would explode/spew everywhere. For us, the spray lasts a very long time. We use it in conjunction with the diffusers, but only spray down low on/around the areas one of our cats tends to go to spray. It really has seemed to make a difference. Hope this helps.

I leave mine on the counter after opening and don't know if it has affected it's efficacy. It works just the same. I hope this helps.

supposed to wait 2 times as long after use before using again. so for 20 seconds you wait 40 seconds before using again. it works well. we use it to load and unload an 800 pound cabinet into our toyhauler.

as long as you shake it well before you spray, as it tends to settle out to the bottom if you just let it sit for a long time. i have done this for years and it always works well.

Buy a new empty spray.bottle. pour the contents of the first bottle into the empty one and use it

I don't think so.I looked into that and it seems to be counter productive.The spray should be all you need.

I set up my room (shut A/C down), set spray and immediately leave room, close door. Don't open for 10 hours at least. I didn't use masks; I wasn't in there long enough.... If you plan to, I'd use a mask & googles
