Tarantulas not making any new "silk home" after I move them.

Here's my story:
I pet 2 Avicularia versicolor.

I put my Ts on an isolated room, and then my father said he want to spray insecticide (http://en.wikipedia.org/wiki/Baygon ) in that room. So I move my tarantulas and all of their accesories and care to another room downstair. My house has two floor. After I move them, my father spray that room. I don't dare to move them back soon, so I wait three day.

Then I buy two plastic container for food to make a new cage for them. I make many holes in the container and make their hide out/ home from plastic botle. I move them into their new container. Then I move the new container back to the isolated room after I wait three days since spraying. I wait two night for them to make their new home, but they didn't make any. Not even a single thread of silk. Usually they will make a new silk home after 1 night only. What did I do wrong? I didn't decorate any of the container because it will make them hard to find roaches.

Some tarantulas do not like to be moved and will sulk for day, weeks or even months before making a new webbing.
Make sure they have fresh water and just leave them alone for a few weeks before you disturb it, no food just water.
Just because you have give them a (clear ?) plastic bottle for a new home doesnt mean that your avic is going to like or use it, try using a piece of bark standinmg upright in a corner or a bunch of plastic plants hanging up.
Dont forget that Tarantulas and Cockroaches are both nocturnal so even if you dont see the spider eat the roach immediately, they will both be out exploring after you have gone to bed.
When I move any avic I just leave it alone for 2-3 weeks so it can settle into its new home before I disturb it.
