If an insecticide says to wait until dry, how long should I wait until I can go back in the room?

Question

For one thing I'm from Canada and if you had a cockroach infestation I'm pretty sure you would use it also, and I have tried natural ways to get the bugs out but they are not working.

Answer 1

By the time you read this it will be OK

30 min is enough. If you have a strong smell, open the windows and air it out.

Answer 2

If you truly value your health and your family's health then you would never use an insecticide-ever-period. They are poisons and toxins that have a negative effect on humans as well as family pets. I would hope that you had the windows open for maximum venilation. Americans are too quick to spray Raid or Black Flag. Why do so many Americans have cancer each year? I would argue that pesticides and insecticides have contributed mightily to cancer in general.
