Rat Exterminator in Melville, NY

Norway rats live close to the ground, tunneling next to slabs, footings and the bottom of steps and using the same worn lanes every night. When one reaches a wall cavity, a trail normally already exists outside, so the walk begins in the grass.

Their draws are quite ordinary: seed dropped under a feeder, a dripping hose bib, a compost heap, firewood stacked on siding. None of these says a household is unclean. They are simply what a rat samples while following a fence line.

Droppings give the cleanest answer. Rat pellets are about as plump as a rice grain with blunt ends, whereas mouse droppings are slim and short. Tooth marks agree, since rats leave broader and deeper grooves.

• Burrow openings roughly fist-sized, ringed by smooth packed dirt.
• Dark grease rubbed along the foot of a wall or pipe.
• Torn sacks of seed or pet food in a garage or shed.
• Thudding or dragging overhead once it is dark.

The outdoor lap comes first and records burrows, feeding spots and any gap near the ground. Traps are placed on the runs, tight to walls, beyond the reach of kids and pets. Indoors, the attic and cellar are checked for the entries the lap pointed toward.

A rat entry needs sterner material than a mouse job. Gaps receive heavy mesh, flashing and a hard sealant, never foam or rags, and the repair is verified from both sides. The sealing page explains what goes where.

Yards here range from small suburban plots to bigger parcels beside wooded parkland, such as the areas people call Arboretum Park and West Hills County Park. We cannot know what a particular lot contains, so describe trees, fences and stone walls when you call, since they shape where the outdoor lap starts.

Caught rats are removed, and burrows are filled in or watched. When droppings and nesting need clearing, the debris and insulation page walks through it. A yard that keeps drawing animals is covered further on the lawn and burrow page.
