Maxforce Pro Roach Killer Bait Gel will work if you are using it per the label. This product should not be the only item you are using when treating for roaches. Our Roach Kits comes with everything you will need to do a complete treatment, including bait gel, an insectide, an insect growth regulator and monitoring traps.
Please take a look at our Roach Guide for tips on how to treat and which products to use to get rid of them.
The Maxforce Pro Roach Bait Gel will stay effective for several weeks after it is applied. After 3 years, the chances of any beneficial residual effects or bait attractant in the gel is unlikely. If you do not currently have roaches, those bait placements could be scraped off and removed.
If you have active roaches, roach bait gel placements need to be reapplied every 2 weeks so that fresh bait is offered in addition to using a residual insecticide and insect growth regulator.
