Forum:Continuous Trap Effect

When face-up Continuous trap cards state "Once per turn", can you activate its effect during your opponents turn?(like the typical trap card)

like for example, an infestation infection is face-up on my field along with an Evilswarm Monster. My opponent activates dark hole, can i chain my trap card so my monster could dodge the destruction and return it to the deck instead in order to add another evilswarm monster to my hand?

If yes then does this apply to every kind of continuous trap card? any exemptions?--119.92.123.171 (talk) 04:47, April 19, 2013 (UTC)
