Pest control in Mernda

Beside Plenty Gorge Park.

Plenty Gorge Park runs past Mernda, so rats and mice share the suburb with protected possums and snakes, and telling them apart decides whether you need a pest business at all.

Mernda and the gorge

Plenty Gorge Park

Parks Victoria describes expansive bushland only 20km from Melbourne, home to an abundant variety of plants and wildlife. Its Plenty River Trail project names a bridge north of Hathfelde Blvd in Mernda and links to Mernda station, so the park is right on this suburb's doorstep.

Rats and mice

The City of Whittlesea lists them as health hazards and says they can damage walls, pipes and electrical systems. That's why a chewed cable in the roof deserves more than a shrug.

Possums

Whittlesea says they're protected by the Wildlife Act 1975 and can't be killed by poisoning or any other means.

Snakes

The council says snakes are protected, are best left alone and will go away by themselves, and that a licensed snake catcher can be called. If someone is bitten, call 000.

Rodent control in Mernda

A good job starts with a walk around the outside. The technician should look at where rodents are coming from, such as stacked timber, the shed, the compost and any gap under a garage door, then at the roof and wall cavities. Bait stations (locked boxes that hold rodent bait) only help if the way in gets closed as well.

A follow-up visit is normal, so ask whether it's included in the written quote and when it would happen. Tell them about kids, pets and allergies so they can plan the treatment and tell you any precautions.

When it's more than one mouse

  • Fresh droppings in more than one room.
  • Noise in the ceiling several nights running.
  • Chewed wiring or insulation in the roof.
  • Burrow holes along a fence, shed or retaining wall.

What you can sort out yourself

You can

  • Keep bins lidded and pet food sealed.
  • Stack timber off the ground, well away from the house.
  • Seal gaps around pipes and under doors.
  • Empty pot saucers and other standing water before the warm months.

Leave to a pest business

  • Finding nests and entry points you can't reach.
  • Setting and checking bait stations.
  • Closing up a roof so a possum can't get back in.

What we'd do about pests in Mernda

Clean up outside first and watch for a week or two. One mouse in the laundry isn't always a job worth paying for. Noise every night is. When that happens, tap what you've found and your postcode.

Questions

Pest control in Mernda: common questions

I've only seen one mouse. Do I need rodent control?

Not always. Seal the gap, remove the food and keep watching. If you see fresh droppings or hear them again over the next week or two, there are likely more.

What should I do about a snake near the gorge?

Leave it alone, keep kids and pets back, and give it room to move on. If it won't, call a licensed snake catcher. We don't take snake jobs.
