Be very careful using an airpump while being fumigated. They could verywell overheat if they cannot get enough air, and if they can get air they WILL be pulling in air from the room.
Turn everything off, cover completely with plastic wrap, seal it. Then to be sure throw a blanket or such over that.
Honestly i would rather lose some BB than lose the tank of fish.
(i tried the air pump thing and lost $300 worth of fish out of my 5ft tank when the house 1st had to be fumigated, learnt the next times!)
Seal tight - tape as backup, plus blanket cover!
