When the weather starts to warm up across Canada, snow will melt away and spring showers will lead the way to lush, green summers. But along the way, we have to prepare for floods.
In May of 2017, many parts of Canada suffered from severe flooding as torrential rain and snowmelt overran the river and drainage systems. Some cities, including Montreal, even declared a state of emergency. While systems are in place to provide immediate relief from floods, it’s important to be prepared for the long-term consequences of flooding, including increased pest activity and pest-related health risks.
Just like you, pests will seek relief from flood waters. For example, rats and cockroaches found in sewage and drainage systems will be forced to higher ground and inside buildings. Crawling insects such as ants, ground beetles and wood roaches that escape the floods will migrate in large numbers into dry buildings.
Even if your property stays dry, it’s still at risk for pest activity, as insects, rodents and other wildlife will move to higher ground untouched by the flood waters.
When flood waters recede, accumulated debris attracts flies, scavenging beetles and cockroaches that feed on the abundance of garbage and sewage overflow. Mold growth also attracts mold-feeding insects like plaster and fungus beetles., and moist soil and pockets of standing water offer breeding grounds to mosquitoes, midges and gnats. Your property also could face a higher risk of carpenter ant infestations and damage as heavy rain and flooding leave behind wet or rotting wood.
While there’s not much you can do to prevent a flood, there are steps that you can take to mitigate the pest-related damage. The first step is to develop and implement an Integrated Pest Management (IPM) program before a flood occurs. IPM strategies focus on preventive controls, like exclusion, sanitation and maintenance techniques, to help defend against pest activity year-round. The ongoing monitoring and prevention will help keep pests away from the property before a flood occurs.
Before flood season begins, meet with your pest management provider to develop a plan for responding to pests after floods and heavy rain. They will be able to tell you which parts of your property are at a higher risk for pest activity and can help establish a corrective or preventive action plan and process for minimizing damage. As part of your ongoing IPM program, here are a few proactive measures you should make to reduce pest activity and prevent flood-induced pest infestations:
There also are steps you can take after a flood to reduce conditions that attract pests. Of course, your top priority in a flood should be your and your employees’ safety, so don’t enter flood waters and take precautions when lifting heavy materials around the property. Once the waters have receded, take the following steps to help defend against pests.
After a flood, it’s also a good idea to contact your pest management provider and ask them to inspect your property. They can help you assess damage from a pest management perspective and provide recommendations for repairs and preventing pest infestations. Seeking a professional opinion is important, as there could be underlying conditions or excess moisture that will attract pests like mold-feeding beetles, cockroaches, rodents, carpenter ants and termites over time. They can also help you adapt your existing IPM approach to respond to changing conditions and excess water left by the flood.
In the aftermath of last year’s devastating floods, emergency preparedness is increasingly important and can go a long way in helping your business recover from these natural disasters. So, take advantage of the opportunity to mitigate pest worries and think about a response plan now, before a crisis hits.
