Alpine Cockroach Gel Bait Rotation 2 Reservoir will be good for three years unopened and one year once the tube has been opened. It does take time for roach baits to work since the roaches have to consume it. We would also recommend doing a complete roach treatment with insecticide, such as Cyzmic CS, and an insect growth regulator, such as Gentrol Point Sources. Be sure not to spray the bait because that will contaminate it and the roaches will not consume it.
Please take a look at our Roach Control Guide for information on how to treat and prevent roaches in the future.
The manufacturer of Alpine Cockroach Gel Bait Rotation 2 Reservoir is BASF.
BASF uses a unique set of numbers to match up that product, when it was made, what lot it was a part of and how many were in that lot. Below you will see an example of a Cy-Kick aerosol can and how it is broken down. The batch numbers can vary in location on BASF products from just above the label on a bottle, to the bottom of a container or can, as well as on the sides of case containers or boxes.
On the bottom of a can of Cy-Kick you will normally see a few sets of numbers appearing as follows:
59011782 15 111
Starting with the first row. The first set of numbers normally starting in 59- ex: 59011782 is BASF's article number for the product.
The second set- ex: 15, indicates the year in which the product was produced. For this can that would mean it was produced in the year 2015
The third set- ex: 111, indicates the numerical day of the year that the product was produced. So it was manufactured on the 111th day of the year of 2015. This comes out to show it was produced on April 21st of 2015.
The bottom row of numbers indicates the batch information. The first set- ex: 203923930, indicates the actual batch/lot number for the manufacturer. The second set- ex: 28570 indicates the container count of each batch.
Based on the numbers you provided it looks like March 2016.
Exact placement of Alpine Cockroach Gel Bait Rotation 2 Reservoir should be based on complete monitoring and inspection. Applications should focus on cracks and crevices in areas where activity has been observed or is likely, such as near water sources, around pipe collars, where utilities enter, around or under appliances, underneath counters, where cupboard frames meet the wall, along drawer slides, along baseboards, doorframes, and windowsills. If using residual sprays, do not use sprays and baits in the same places: keep sprays in low areas on or near the floor and use baits in higher locations. The sizes of the bait would be pea size points, with approximately 10 spots per 100 sq. ft.
