Seeing insects during a mild winter day?
If insects appear around windows in your Lebanon, MO home during a warm spell, photograph them before choosing treatment. The insect may already have been sheltering in the building. A change in weather does not establish where it came from or whether an indoor colony is present.
Cluster flies can become active on mild winter days. Read University of Maryland Extension's cluster fly guide.
Record the pattern
- Which window, room or wall has activity?
- Is it one insect or repeated sightings?
- Do insects appear when that part of the building warms?
- Have similar insects appeared in previous years?
Make practical maintenance part of the plan
Keep accessible storage organized, check damaged door seals and report moisture problems. Have repairs made without blocking required ventilation. If animals may be inside an opening, discuss occupancy before sealing it. An inspection can help you decide which conditions matter for the identified pest.
Choose service based on the findings
Explore individual pest services, including ant control, spider control and rodent service. Different pests need different approaches. Ask about the proposed work, preparation and follow-up before service begins.
