When to expect house wrens in Wisconsin
House Wrens are summer residents in Wisconsin, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on beetles, caterpillars and crickets; spiders and flies.
Humid continental, with two Great Lakes shorelines, northern forest and southern prairie-oak savanna.
Nesting in Wisconsin
Across Wisconsin, house wrens typically nest from June–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.
Warm, humid summers.
- Have boxes cleaned and mounted before May — 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.
