Maxforce FC Roach Bait Gel will remain effective for months once it is applied. However, what really determines how often you should apply it is how much activity you have. If you have a lot of roach activity, then once you apply the product it could be eaten by the roaches in just a few days and you would need to re-apply often to keep up with the activity. Roaches will still eat the gel even if it hardens. Any gel that is not consumed should be cleaned up and reapplied as needed, or at least every 2 weeks.
