Since these use different bait attractants particular to the insects they are made for, we would not recommend using the Advion Cockroach Bait Arena and the Advion Ant Arena close to one another.
Example. you could place the ant arena on a window sill, counter top, under the sink and place the roach bait arena in another location, under cabinets, behind appliances, between dishwasher and refrigerator, etc.
The Advion Cockroach Bait Arena has a shelf life of 5 years. Any bait arenas that have not been used would still contain bait and be fine to use. Once in use, the arenas should be replaced every 3 months.
Advion Cockroach Bait Arena will help get rid of an infestation and only attracts those already in the area. You may see more activity when using a bait especially if you are only seeing 1 or 2 at a time. We would recommend reviewing our Inspection guide to confirm an infestation and our How to Prevent Roaches guide for the best advice if you are only seeing a few.
