### Ant Control

- URL: https://crdpestcontrol.com/services/ant-control/
- Summary: C.R. Davis III & Sons Pest Control treats ants in homes across Chester County, Montgomery County and Delaware County from our Phoenixville base. The ants most often found in southeast Pennsylvania kitchens include odorous house ants and pavement ants, with carpenter ants in damp wood. Each nests in a different place, so we identify the species first and place bait and treatment where that colony lives.
- Species here: Odorous house ant (Tapinoma sessile), pavement ant (Tetramorium caespitum), black carpenter ant (Camponotus)
- Active season: Spring through fall; pavement ants can swarm indoors in winter in heated buildings
- Signs: Single-file trails to sweets, sand piles at slab cracks, winged ants at windows

### Carpenter Ant Control

- URL: https://crdpestcontrol.com/services/ant-control/carpenter-ants/
- Summary: C.R. Davis III & Sons Pest Control treats carpenter ants in homes around Phoenixville and across Chester County, Montgomery County and Delaware County. The black carpenter ant nests in moist, decaying wood, often with a parent colony outside and satellite nests in the house. We find both, place treatment where the ants live, and show you the moisture problem that drew them in.

We name the species first, because a paper wasp nest under a porch ceiling and a yellow jacket colony inside a wall void need very different work.
- Species we see most: Paper wasps, bald-faced hornets, eastern yellow jackets, European hornets
- Nests start: May, when overwintered queens begin building (Penn State Extension)
- Most defensive: August and September, as colonies peak and food gets scarce

### Carpenter Bee Control

- URL: https://crdpestcontrol.com/services/carpenter-bee-control/

We treat active galleries per the label and show you how to plug and paint so the wood stops attracting them.
- Species here: Eastern carpenter bee (Xylocopa virginica), the only large carpenter bee in Pennsylvania
- Active season: Nest building in April and May; new adults emerge in August and overwinter in the tunnels
