How long a gel bait stays soft depends on where you place it. If you place the gel outside or on concrete or cardboard which soaks up moisture, it will only stay soft for a couple days at best. If you place it indoors in one of our bait stations for gel, then you can usually get about a week out of it. However, just because the bait hardens does not mean it is not effective. Roaches will eat hardened bait for up to 3 months after it is applied.
