Common Prepositions Used with Infested

The word infested is usually followed by the preposition with, which indicates what is causing the infestation. For example, one might say The house was infested with termites or The garden is infested with aphids. This structure is standard in English and is widely accepted in both formal and informal contexts. Using with after infested allows the speaker or writer to clearly identify the source of the infestation.

Examples of Infested with

The old attic was infested with spiders.
The abandoned building is infested with rats and cockroaches.
Her kitchen became infested with ants after the summer picnic.
The fish pond was infested with algae and invasive plants.
The field was infested with locusts, destroying the crops.

In these examples, the preposition with directly connects infested to the noun that specifies the invader or problem. This construction is simple, clear, and widely understood by native speakers and learners alike.

Less Common Prepositions with Infested

While with is the most common preposition used with infested, other prepositions sometimes appear depending on context. For instance, by can occasionally be used, especially when describing the agent responsible for the infestation in a more passive or causative sense. For example, The crops were infested by locusts. However, by is less frequent and may feel slightly formal or technical in everyday speech.

Examples of Infested by

The cellar was infested by mold due to poor ventilation.
The picnic area was infested by bees after the fruit trees bloomed.
The old ship was infested by barnacles along the hull.
The abandoned warehouse was infested by pigeons.

Using by emphasizes the agent causing the infestation rather than the general state of being overrun. This subtle distinction can be important in scientific writing, reports, or formal descriptions.
