The short answer

All Corners Pest Control exterminates cockroaches in homes, rentals and businesses with two options: a low-toxicity gel with powder and dust that needs no preparation and takes three to four weeks for full effect, or a chemical spray with powder and dust that works in one to two weeks. Cockroaches are treated twice, three weeks apart.

Signs of cockroaches

Seen at night

Cockroaches hide during the day. One running when the kitchen light goes on usually means more out of sight.

Droppings

Small dark specks like pepper or coffee grounds in drawers, cupboards and behind appliances.

Warm, damp hiding spots

Behind the fridge and stove, under sinks and around the dishwasher.

Treatment

Two ways to treat cockroaches

No preparation

Gel formulation plus powder and dust

Less obtrusive and needs nothing from you beforehand. It takes a little longer to reach full effect.

  • Low-toxicity gel bait
  • No preparation needed
  • Vapour-free, fume-free and odour-free
  • Full effect in three to four weeks
Fastest

Chemical treatment plus powder and dust

Hits cockroaches strong and fast, and keeps working after it dries.

  • Kills on contact and leaves a residual that prolongs the effect
  • An aerosol disrupts development so eggs do not hatch
  • Preparation needed, mainly in the kitchen
  • Full effect in one to two weeks
How it works

What happens after you call.

  1. Call or send a request

    Tell us where you are seeing them. We help you choose the gel or the spray option.

  2. Prepare if needed

    The gel needs nothing. The spray needs the kitchen and bathrooms cleared, per the checklist.

  3. First treatment

    Gel, powder and dust, or spray, powder and dust, in every area cockroaches use.

  4. Second treatment

    We come back three weeks later for the second treatment. Until the problem is gone, do not wash cupboards or near the baseboards.

Safety and preparation

Before and after your visit.

For the spray treatment, all people and pets stay out of the home for 4 to 5 hours. Children aged 2 and under, anyone pregnant and anyone with breathing problems stay out for at least 24 hours.

Cover or remove exposed food, and cover food preparation surfaces and utensils before treatment or wash them after.

After the treatment

  • Leave the treatment in place until the problem is gone. Do not use wet wipes or wash the cupboards, drawers or the floor near the baseboards.
  • Sweeping and vacuuming near baseboards is fine. When you mop, stay about 12 inches away from the baseboards.

What affects the price

  • The size of the property
  • How far the problem has spread
  • The condition of the property
  • Hard-to-reach areas
  • After-hours visits

FAQ

Cockroaches: common questions.

Straight answers. If yours is not here, call 905-385-1818. The phone is answered 24 hours a day.

How much does cockroach extermination cost?

It depends on the size of the home or business, how widespread the activity is and which option you choose. Call 905-385-1818 for an estimate on the phone. You know what you are paying before the work starts, with no hidden costs.

Do I need to prepare for cockroach treatment?

Not for the gel option, which needs no preparation. The spray option needs the kitchen and bathrooms cleared, with cabinets and drawers emptied. See the cockroach checklist.

How long does it take to get rid of cockroaches?

Cockroaches are treated twice, three weeks apart. The spray reaches full effect in one to two weeks, and the gel in three to four weeks.

Is the cockroach gel safe?

The gel is a low-toxicity formulation and is vapour-free, fume-free and odour-free, which is why it needs no preparation.

Can I clean my kitchen after the treatment?

Sweep and vacuum as normal, but do not wash cupboards, drawers or the floor near the baseboards until the problem is gone. The treatment keeps working as long as it stays in place.
