There are many ways to solve arachnophobia... I recommend giving some of those a try.
To prevent chemical cross-contamination the proper location of surface bait stations is to place rodenticide baits rightly into rat burrows. This may have a quick result and rapid bait uptake and effective treatments for those who have neophobia that avoids bait stations.
I think you should review each lesson on those sports.
