Pest Control Techniques - FAQ Here we explain the details of proven methods for pest removal and control

What pest control chemicals are used?

The pest control chemicals used depends on the type of pests we are dealing with. However, all of the chemicals we use are harmless to humans and pets.  

Rodents are most effectively controlled by using bait loaded with rodenticides that is locked in a tamper-resistant bait station. Today, there are a variety of rodenticides available, which work as a single dose anticoagulant. Depending on the situation, rodent traps may also need to be used.

Pest control for crawling insects may take different forms with chemicals such as dilatable pesticides, oil-based residual pesticides, non-residual pesticides and powder. Since situations vary and every pest is different, the choice of chemicals varies, but all chemicals used are approved by the Pest Management Regulatory Agency or PMRA.

Powders will often be used in hard to reach areas like cracks and crevices to ensure a long-lasting effect. The powders will need to remain free of dirt and humidity to be effective. Powders also work effectively as a flushing agent.

Oil-based chemicals are used as non-residual pesticides to mainly flush out pests that may be hiding in otherwise inaccessible areas of a structure. Dilatable pesticides are mixed with water before being used to target pests like cockroaches, bed bugs, centipedes, ants, flying insects, spiders, etc.

The dosing for each type of chemical we use varies and depends on the product as well as recommendations by PMRA. Chemicals that are meant to be mixed with water are available in highly concentrated forms, with different formulations like Soluble Concentrates and Emulsifiable Concentrate, etc.

Commercial grade chemicals can only be purchased and used by licensed, trained, insured, and bonded pest control companies like Pesticon. The chemicals are used with care by a seasoned and licensed exterminator. Pesticon also ensures that the right post-pest treatment measures are followed to ensure further safety and effectiveness of the extermination process.

Do we need monthly pest control?

Businesses that are in the food serving or manufacturing industry certainly need weekly, biweekly and monthly pest control to ensure that their environment is clean and sanitary. We also recommend warehouses, greenhouses and all other commercial and industrial facilities get regular pest management.

Pest issues are unavoidable for most industrial and commercial businesses, which is why active management programs are so important. We use different exterior and interior pest management systems to ensure effective pest control. For example, we may use exterior bait stations to ensure that facilities are free from mice and rats. 

We offer a home protection plan for residential pest control. The plan helps keep homeowners safe throughout the year from a variety of common pests. You can find out more here.

How long do you have to stay out of your house after pest control work has been completed?

It is not necessary to vacate the premises for every type of pest control procedure. For example, we may use dust (powder) and gel for cockroaches, dust and bait for ants, and baiting for rodents (mice and rats). These procedures do not require lengthy stays away from your home. The only precaution is to avoid the area while pest extermination is physically in process.

If we are using chemicals to exterminate flying and crawling insects, it is best to vacate the premises for up to 6 hours. You’ll also want to keep the property well ventilated by opening doors and windows for 10-15 minutes before re-occupying the premises.

How to control insects in my house?

Habitat modification is a key aspect to controlling insects in your home. For example, you can change the humidity of your home and use use caulking and sealing to block off spots that harbour pests. However, in the majority of cases, you’ll need to start with professional extermination.  

All pests have their own ways of invading your home:

Bed Bugs

Bed bugs will travel with you from an infested location like a motel, hotel or another person’s home.


Cockroaches will often follow you from the grocery store and come hidden in cardboard packaging. They may also infest your property from any utilities you may be sharing with a neighbour. Sharing walls in your property, condo, townhome, and semi-detached home means that your neighbour's cockroach problem soon becomes yours.


Rodents will generally enter your property via air vents, central vacuuming pipes, air conditioning pipes, and a variety of other pipes on the property. You’ll also be invaded if the front door, garage door, or back door is left open by mistake.

Carpenter Ants

Carpenter ants will nest in the window frame or the door frame and sometimes behind plumbing pipes where there is a lot of moisture and humidity. In some cases, you may be able to remedy the situation by changing the old window or door frames. Carpenter ants can also end up in your kitchen while searching for food.

Pharaoh Ants

Generally, like all other ants, they are attracted to moisture and a good food source. So, by eliminating bread crumbs, maple syrup drips, etc., you can get rid of pharaoh ants, but professional extermination can help you get rid of them sooner.
