TS interference

[Guest]

If a TS were to occupy one of my apartments, would that keep the PMS away?

Richard. Seems to depend. Sometimes the TS will not push PMs out. Especially if the PMs have been there a few years. However, if your colony is just forming, or is very new, the TS will probably chase them off. The ideal situation is to have the TS in their own housing (Blue Bird style house, or gourd) around 35 feet from the PM housing. If you have Blue Birds, you could put up two BB style houses around 10 feet from each other, and possibly get all three to nest. CUL Lou
