Read the yard before you read the house.
Rodents often start outdoors. They settle where food, cover and a burrow site are close together, and move inside when the house offers a better deal. Fixing the yard early can stop the problem before it reaches your walls.
About 8% of Little Silver homes sit directly on the Shrewsbury River, and roughly another third sit on streams that connect to it. Norway rats travel along those banks, so if your lot backs onto a creek, start your walk-around on the wet edge of the yard. Burrows and foundation gaps along that edge are the ones most likely to matter.
How to tell what dug that hole.
Not every hole in a yard is a rat burrow. Chipmunks, moles, voles and squirrels all dig, and each needs a different response. Use this table to narrow it down before you buy anything.
| What you see | Likely animal | What it tells you |
|---|---|---|
| Hole about 2 to 3 inches wide, smooth worn edges, often beside a foundation, deck or shed slab | Norway rat | Active burrow. Look for a runway of packed dirt and gnawed food scraps nearby. |
| Small hole about 1 inch wide in a garden bed or under a step | Mouse or vole | Mice use burrows near food. Voles leave narrow surface trails in grass. |
| Volcano-shaped mound of loose soil with no visible opening | Mole | Mounds are pushed up from tunnels below. Not a rat sign by itself. |
| Hole with a tidy, scattered soil fan near a stone wall or step | Chipmunk | Usually seasonal and rarely enters the house. |
| Tunnel opening angled under a woodpile or shed edge, with droppings about 1/2 to 3/4 inch | Norway rat | Blunt droppings this size point to rats and mean the site is in regular use. |
The usual yard attractants.
Gardens and compost bins are the most common food source we see. Ripe tomatoes left to rot, fallen fruit under apple or pear trees, and open compost piles with cooked scraps all draw rats. Little Silver's farm and nursery past left fertile soil, and gardens are common. A well-tended vegetable bed can also be a steady meal for a rat, so pick ripe produce promptly and keep beds clear of fallen fruit. Dog food left in a bowl on a patio works the same way as bird seed.
Bird feeders come next. Seed that falls to the ground feeds rodents all night after the birds are gone. Woodpiles stacked against a wall, sheds set on the ground, and low decks give them shelter. A rat that finds food and cover in the same corner tends to stay put.
Sheds and decks deserve a closer look than most people give them. A rat will dig along the edge of a concrete pad or under low deck boards, then line the burrow with shredded paper and fabric. If you can only see a dark gap under the structure, a technician with a flashlight and a mirror can check it in a few minutes.
A yard with no food and no cover is a yard rats move on from.

What treatment outdoors looks like.
We start by locating every active burrow and runway, and we mark where droppings and gnaw marks show up. Rats often have several openings, so plugging a single hole tends to push them to another. We also check the foundation line, deck edges and shed bases to see where they might travel into the house.
Treatment usually combines trapping along runways with tamper-resistant bait stations placed out of reach of children, pets and wildlife. We do not scatter loose bait. Poison can hurt dogs, cats and hawks and owls that eat a poisoned rodent, so placement matters. Once activity stops, burrows are filled and the edges are closed. If the animals were already getting indoors, our rodent exclusion service closes those gaps, and rat control covers how we handle established infestations.
Why you may need a follow-up look.
Rodent numbers near creeks and low ground swing with the seasons and the weather. Heavy rain or a high tide can drive animals out of banks and into yards for a few days. If you saw a burrow after a storm, tell us when it first showed up. Fresh soil and a clean, shiny hole edge usually mean the burrow is in use right now. A few photos of the hole, taken from the side with something for scale, help us judge how fresh it is.
