Wet Drains Keep Cockroaches Away

We recently had a call from a client who had cockroaches coming up through the drain of his bathroom floor. Today, we’re sharing some of the advice we gave them on understanding cockroaches and how their infestations happen.


How Cockroaches Live

  • First of all – long! Fun fact: cockroaches have been around since the time of dinosaurs.
  • In fact, cockroaches have evolved into some of the most durable creatures on the planet. Not only are they hard to kill, they naturally are resistant to dying since they can go a month without food, 40 minutes without air, and can even live a week long without a head!
  • While cockroaches invade all sorts of buildings, many of them start life outside among vegetation.
  • Heat is their enemy – when temperatures rise, they look for cooler places to migrate to. They can invade buildings through underground and in-wall piping, where they can keep safe, dry and cool while they unpack their luggage.
  • The problem begins when they lay eggs as they explore. When those eggs hatch, you have an entire army of these pests in every nook and cranny before you realize what happened!


When cockroaches come up through drainage, this is what’s happening:

  • They’re in the process of moving in, and they’re laying eggs along the way.
  • They are hungry and looking for food.
  • If you see one cockroach, there are going to be more.
  • Expect other odours to follow in their wake, since they are literally dragging outside material inside your drainage system.


What to do about an infestation

We can’t remember the last time cockroaches haven’t been busy invading some house or apartment building. We also can’t remember the last time that regular insecticide was actually good enough for stopping a roach problem. At this point, it doesn’t make sense to waste money on several cans of insecticide. The best suggestion we can offer is to get the professionals dealing with them as soon as possible. The high-grade chemicals that companies like ours use are very hazardous and must be professionally controlled. But, they are the best and quickest way to get rid of an infestation.


Preventable Measures

  1. While cockroaches like warm and damp areas, they do not enjoy swimming. “P,” “J,” or “U” shaped traps hold water. You can find traps like this under just about every kind of sink. This isn’t just good for blocking sewer odours from flowing back into your house, but they also are good for blocking swimming-averse pests from coming up your drainage.


  1. Cockroaches aren’t just ugly (and scary for some), they’re dangerous and fast! They can trigger asthma attacks and allergies, and they spread huge amounts of bacteria wherever they go just because they walk in very dirty areas then come inside. They can run up to three miles an hour, meaning that if they wanted to, they can spread disease at a very quick pace. This means that quarterly cockroach prevention check-ups should be a critical part of your building maintenance routine. This is especially important for buildings with vulnerable individuals, such as households with young children or elderly people, restaurants, day-cares, and hospitals.


  1. Make it hard for cockroaches to invade – pour a few cups of water every week down drains that are rarely used. Dry drains are the easiest path that they will take to move in. If the area is hot and the water is likely to evaporate quickly, pour a thin layer of mineral oil or cooking oil down the drain right after you wet it. That way, the drain will remain moist for some weeks.


  1. Get a trap primer: Plumbers can install trap primers in your water supply – this is great for commercial buildings. The trap primer can detect when water evaporates from traps then refill them with a release of water. Liquid trap seal primer is another optionPour some water down your drain, then pour this odourless, biodegradable liquid right after. Liquid primers last three to six months or longer.

These methods will help prevent a cockroach takeover and also help stop sewer smells from flowing into restrooms and other areas with plumbing. Odours aren’t just smelly, they’re dangerous –the toxic gasses can cause serious health issues in children and adults alike. So, drainage maintenance is crucial for the health and safety of your property.
