Cockroaches are very closely connected with the human environment and have become unwanted pests worldwide. Cockroaches are attracted to buildings where there is food, dampness and, in colder environments, and warmth. They feast upon a large range of human food and also organic products like card board, glue, feces, dead creatures and fellow cockroaches. They can acquire diseases from the dirt in their environments and easily transmit them onto food and surface areas.

Cockroach Treatment

You don’t need to stay away from your house since we use a low mammalian toxicity insecticide, without any internal smell. You don’t have to clear cabinets or wash anything after the treatment has been finished. Harmless to be used around kids and household pets.

Our Part: Interior spray to skirting boards. External spray to garage, sheds, fencing lines, paths, windows, gutters, fascias. Dusting to roofing void (accessed from inside of the house), sub floor, Telstra pits, cracks, crevices and weep holes. Gel affected locations for German cockroaches.

Your Part: Don’t put the washing out, clean up prior to treatment, cut the yards, restrict your garbage outside and clean up internally. The more things away from the wall inside the better the buffer. Keep doors and windows shut until the spray dries. Clean behind the refrigerator and beneath the microwave oven.

Cockroach Control

The treatment for German cockroaches differs from bigger cockroaches. Caste Hill Pest Control utilise gel to eliminate German cockroaches– using powder, gas, and conventional sprays will only temporarily halt them.

Large cockroaches are addressed using a basic spray that includes treatment of roofing system spaces, internal skirting boards and exterior spots.

Large Cockroaches:

Roof: Dust/powder is dispersed into the roofing cavity by the means of a dust gun. The technician will use a ladder to access the roof cavity through the manhole and the dust will be spread throughout this space.

Internal: An indoor buffer spray will be applied to the skirting boards all over the house. All rooms will be treated with the skirting board spray. Dust may also be placed on any cracks & crevices within the house.

Sub Floor: Dust/powder is going to be sprayed into the area below the house.

External: Spray will be applied to these spots: around windows, gutters, fascias and so on. Garage areas, sheds, walkways, fencing lines, laundry, weep holes, cracks and crevices and Telstra pits

How Does the Spray Get the job done?

cockroach controlThe spray that’s utilised for large cockroaches also covers you for other unwanted pests including webbing spiders, redback spiders, carpet beetles, silverfish, creamy coloured crickets and any current wasp nests.

The dust and spray technique used for large roach control not only eliminates the existing population but will also offer long-lasting security as a recurring protection is created.

A roach will walk over this buffer and meet this buffer, and as cockroaches usually lick themselves clean they end up absorbing the poison.

Treatment Preparation


  • Don’t hang the washing out, clean up internally. The more things away from the wall inside, the better the buffer.
  • Keep doors and windows shut until the spray dries.
  • Clean behind the refrigerator if accessible and below the microwave oven.
  • Limit the clutter within the property as having a messy house can introduce pest infestations to your home and become a harbourage area for unwanted pests.
  • Limit paper items and dispose off cardboard boxes.


  • Trim the yards
  • reduce your garbage outside
  • clean up the backyard location
  • pack away kids or pet toys.
