When to expect house wrens in Idaho
House Wrens are summer residents in Idaho, arriving shortly before nesting begins in May and leaving after the young are independent. Through the season they feed on beetles, caterpillars and crickets; spiders and flies.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, house wrens typically nest from May–August. Nest site: almost any cavity — boxes, gourds, even boots and flowerpots; males build several stick-filled dummy nests. Females lay 3–10 eggs, incubate for 9–16 days, and young leave the nest after 15–17 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- Have boxes cleaned and mounted before April — house wrens begin prospecting ahead of egg-laying.
- Use a 1 to 1 1/8 in round entrance on a 4 × 4 in floor, mounted 5–10 ft near shrubs.
- Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
- Clean out old nests after each brood and again after August.
