Whether introduced accidentally or intentionally, these species often thrive in new areas due to lack of natural predators, quickly outcompeting native species for resources. Invasive species pose a significant threat to ecosystems, property and public health. For pest management professionals, understanding and addressing these threats is crucial. 

Understanding Invasive Species

Invasive species are organisms – plants, animals, insects – that are introduced to regions where they don’t naturally occur and cause harm to the environment, economy or human health. Unlike nuisance pests, invasives often spread aggressively and have long-term impacts on property. 

Common invasive pests affecting residential and commercial landscapes include:

• Emerald ash borer: A destructive beetle that kills ash trees.
   
• Spotted lanternfly: Known to damage trees and crops like grapes and apples. 
   
• Red imported fire ants: Aggressive stinging ants that form massive colonies. 
   
• Norway rats: Rapid breeders with a destructive impact on structures and food supplies.

These pests disrupt native ecosystems, degrade habitats and contribute to the loss of native species – all while posing real challenges to landowners and pest professionals alike. 

Identification and Monitoring

Early detection is essential to limiting the damage caused by invasive species. Tools and techniques for identifying invasives include:

• Visual inspections: Look for signs such as unusual plants, burrow holes, insect egg masses or structural damage. 
   
• Pheromone traps and lures: Useful for monitoring insect activity and population density. 
   
• Remote sensing and GIS mapping: helpful for identifying large-scale invasions and tracking their spread.

Regular monitoring allows for the timely implementation of control measures. Educating property owners about what to watch for – like changes in vegetation health or the appearance of unfamiliar pests – can also enhance early detection efforts. 

Control and Management Strategies

Once an invasive species is identified, prompt and targeted action is key. Pest control approaches fall into several categories:

• Mechanical control: Physical methods such as trapping, hand removal or barriers to prevent pest movement. 
  • For Norway rats, consider using bait stations like Bell Labs Evo Express with Trapper T-Rex snap traps and Contrac bait blocks. 
     
• Biological control: Introducing natural enemies like predators or parasites to suppress invasive populations. This should only be done under expert guidance to avoid unintended consequences.
   
• Chemical control: Adjusting human practices – such as proper landscape maintenance, removing infested material or modifying irrigation practices – to create less favorable conditions for invasive pests. 
  • For emerald ash borer, consider utilizing LESCO Bandit or ArborJet Tree-Age R10 Insecticide.
  • For spotted lanternflies, consider using LESCO Crosscheck or Safari 20 SG Insecticide.
  • For red imported fire ants, consider using Advion Fire Ant Bait or Top Choice. 

Prevention and Education

The best defense against invasive species is prevention. Pest professionals can help prevent the spread by: 

• Inspecting new plant material before installation. 
   
• Cleaning equipment and vehicles between job sites to avoid transporting seeds, insects or larvae.
   
• Properly disposing of infested materials in sealed containers or designated facilities. 
   
• Sealing entry points in homes or commercial structures to deter pests from moving in.

Educating clients and communities about invasive threats is just as vital. Workshops, signage and informational handouts can all promote awareness and encourage proactive behavior.

Invasive species are a serious and growing concern for pest control professionals, property owners and communities alike. From disrupting ecosystems to damaging property and posing health risks, these non-native pests require constant vigilance and effective management. By identifying threats early, using a combination of control strategies and educating others, pest professionals can play a critical role in safeguarding both landscapes and local environments.
