Cockroach control

Hello, I hope you are well. I would like to know if cockroach spray/dust is safe for infants. I live in an apartment and they are spraying to get rid of cockroaches. I have a 1 month infant. They have said that we need to leave the apartment for 4 hours after they spray. I would like to know if it is safe for my infant to re-enter the apartment after 4 hours. Please let me know. Thanks. Mississauga, Ontario

It depends on the specific pesticide being applied. If it is a synthetic pyrethroid (commonly used in cockroach control), it probably would be prudent to wait a bit longer than four hours. A Canadian government web page on pesticide safety recommends waiting 12 hours unless specified otherwise on the pesticide label – Click here
