01Sightings keep happening outside
Make a short record of where and when you already saw snakes. Separately note known rodent activity and visible brush or log piles. Keep observations separate from conclusions: repeat sightings do not tell you whether it is the same animal, where it lives or which condition brought it there.
Notice next: Use existing observations to choose what to discuss with a wildlife professional; do not seek a closer encounter to complete the record.
02You are deciding what to change
CDC's prevention guidance gives two concrete starting points: rodent prevention and reducing brush or log piles. Discuss how that work can be done without handling snakes. If a snake is present in the work area, keep away rather than trying to move it so the job can continue.
Notice next: Ask the person assessing the property to separate observed conditions, proposed prevention work and anything still unconfirmed.
03A snake appears after prevention work
Record the sighting and what work had actually been completed. A later sighting does not by itself establish a cause or show that another product or removal job is needed. Review the observations before choosing further work; do not treat a quiet period as proof that encounters cannot recur.
Notice next: Compare dated observations with the agreed work record, without promising a sighting-free deadline.
04A snake is now inside the home
Pause the outdoor-prevention task. Keep people and pets away and contact animal control; do not handle or trap the snake. The linked indoor-snake answer covers that separate immediate decision.
Notice next: Tell the contact that the snake is indoors and its species is unconfirmed. A possible bite remains a medical emergency.
