Adult phymateus leprosus have a habit of invading spaces in search of food, which include both natural environments and human dwellings. Their presence in homes and gardens can cause distress due to their appearance and minor agricultural damage as they feed on vegetation, creating a mild but noticeable conflict with human inhabitants.

To prevent issues with phymateus leprosus, sealing entry points in homes, such as cracks and crevices, is pivotal. Likewise, maintaining clean surroundings by removing food sources that attract these insects can greatly reduce their presence. Employing physical barriers like nets over windows can also deter phymateus leprosus invasions effectively.

If one encounters trouble with phymateus leprosus, maintaining a clean and clutter-free environment can help minimize their impact. Using non-toxic repellents in areas where these insects are common can deter them without causing harm. Install screens on doors and windows to prevent entry. During the recovery of any vegetation affected by phymateus leprosus, avoid overwatering or overfertilizing plants to prevent attracting more pests. Ensure that all food sources that could attract phymateus leprosus are securely stored, minimizing their incentives to invade human-inhabited areas.

Adults of phymateus leprosus are mild nuisances; their tendency to enter homes and fields can lead to noticeable but generally not severe distress. Limited agricultural impact but can cause unrest due to their presence and minor damage.

Phymateus leprosus populations can irrupt in numbers, causing damage ranging from mild to severe. The nymphs and adults chew on plant tissues including leaves, stems, flowers, fruits, and seeds, leading to stunted growth, decreased yields, and even plant death. In large infestations, economic losses to agriculture can be significant, potentially impacting food supplies and prices.
