The optimal window for rodent exclusion in Randolph is August through October — before temperatures drop and rodents begin actively seeking entry into heated structures. Mice can enter through gaps as small as a dime; rats through a quarter-sized opening. Once rodents establish inside a structure, both population removal and structural exclusion are required. Exclusion before the search begins is significantly simpler and less expensive than addressing an established infestation after winter entry.

Active subterranean termite infestations are most commonly treated with liquid termiticide applications to the soil around and under the foundation, creating a treated zone that kills or repels foragers. Termite bait systems are an alternative approach that uses delayed-action toxicants carried back to the colony. Drywood termites may be treated with localized injection or whole-structure fumigation depending on infestation scope.

A termite bait station is a plastic housing installed in the soil at intervals around the structure perimeter. Inside is cellulose material that termites locate while foraging. When activity is detected, a delayed-action active ingredient is added. Workers carry the material back to the colony and distribute it to nestmates, eventually eliminating the colony. Bait systems require ongoing monitoring to function correctly.

Liquid termite treatment involves applying a termiticide to the soil around and beneath a structure's foundation — through trenching and rodding around the perimeter, injection through concrete slabs at regular intervals, and treatment beneath slabs where accessible. Repellent termiticides create a treated zone termites avoid; non-repellent termiticides are carried back to the colony by workers who contact the treatment zone.

Non-repellent liquid termiticides applied by licensed professionals typically maintain effectiveness in the soil for five to ten years under standard conditions, though soil type, moisture, and disturbance can affect longevity. Bait systems require ongoing monitoring and periodic replenishment. The specific duration depends on the products used, application conditions, and whether the soil treatment remains undisturbed.

Consumer-grade termite products are generally insufficient to protect a structure from active infestation. Effective liquid treatment requires rodding and trenching equipment to achieve uniform soil placement at depth. Improperly applied consumer products may kill surface foragers without establishing a protective treatment zone, creating a false sense of security while the infestation continues.

Subterranean termites cause an estimated $6 billion in structural damage annually in the United States. In severe infestations, termites hollow out floor joists, wall studs, and support beams from the inside, leaving intact-appearing surfaces that mask complete structural failure. Worst-case scenarios involve significant portions of structural framing needing replacement in addition to termite treatment.

Termites target cellulose, which is present in all wood species, though they show preferences for softwoods over hardwoods and for wood with elevated moisture content. Pressure-treated wood resists subterranean termite attack in soil contact, but the treated zone is limited to a few inches from the surface — termites can bridge treated wood with mud tubes to reach untreated wood above.

Mud tubes are tunnels constructed by subterranean termites from soil particles, feces, and saliva to maintain the moist, dark environment they require while traveling above ground. They appear as pencil-to-thumb-width tubes running along foundation walls, over concrete, or up wood framing. Flattened tubes over smooth surfaces and exploratory tubes on exterior walls are all termite mud tube types.

A termite swarm consists of winged reproductives — alates — emerging from a colony to find mates and establish new colonies. They appear as clouds of flying insects near windows, doors, or light sources, often following rain and warmth. Termite alates have equal-length wings that extend past their bodies and straight antennae, distinguishing them from flying ants, which have pinched waists and bent antennae.

No. Both are winged reproductives that swarm seasonally, but termite alates have straight antennae, equal-length wings, and no pinched waist. Flying ants have bent antennae, wings of unequal length with the front pair longer than the rear, and a distinctly pinched waist between the thorax and abdomen. Misidentification leads to the wrong treatment approach.

Subterranean termite colonies nest underground, often several feet below the foundation, making the colony itself inaccessible for direct inspection. Colony presence is inferred from evidence — mud tubes, damaged wood, swarmers, and monitoring station activity. Professional termite inspections identify all active indicators and likely entry points without requiring colony excavation.
