An Advanced Look At Scrapes & How They Can Factor Into Hunting Strategy

Bucks are beginning to shed velvet across much of North America so it seems like a good time to discuss one of the most recognizable signs left by the elusive whitetail.

Several decades ago, hunting for a buck near a scrape was very popular, sort of like food plot hunting is these days. Growing up I read many articles about scrape hunting tactics in outdoor magazines. In more recent years, telemetry studies have shown most scraping activity occurs at night. Current conventional wisdom has shifted to the belief that hunting a scrape is low odds for a mature whitetail buck.

However, I think there is more to scrapes than meets the eye.

Most hunters know scrapes are typically located near destinations such as bedding or food or intersecting travel routes. On top of that, scrapes can be created somewhat randomly by rut crazed bucks. Deer are most active after sundown so naturally most sign occurs at night. Location is everything, and I will go into more detail on that in a few paragraphs.

The type and frequency of scrapes you see in the woods depends a lot on deer densities and age structure of bucks in the herd. Low densities and few older bucks result in less sign including scrapes. But there still might be a great buck using that scrape you just found.

The striking difference between a 30-inch wide “big” primary scrape in northern Wisconsin (left) and a six-foot wide one in Iowa farm country (right) represent the differences in habitat, deer densities and age class of bucks.

Although I will describe some general types of scrapes in this article, do not get hung up on names or labels. Study patterns where you hunt and apply that to your tactics.

Location, Location, Location

It is usually easy to identify primary/community scrapes from the large number of more lightly used scrapes that pop up every rut. Primary scrapes may appear perennially and are often used by many different bucks. Broken and worn licking branches can be spotted while scouting at other times of the year, even in the summer when ground vegetation covers any sign of the scrape.

Back to location. A small proportion of scrapes see a lot of daylight activity. These are typically in secure areas in close proximity to buck bedding. Just how many scrapes fall into this category depends on factors including deer herd structure and hunting pressure.

Scrapes near bedding are a major component of my bow hunting strategy. You cannot disturb them with pre-hunting prep or trail camera checks any more than you can disturb the bedded buck that is likely nearby. I look at a primary scrape in security cover near bedding as a virtual bottleneck that every buck will pass by on their way to and from their bed. The scrape becomes a focal point to target the adjacent bedding location. It is often my kill site.

This fully mature buck worked a scrape mid-morning within his public land bedding area on the first high pressure day after a cold front in late September. Putting a camera on a scrape within a bedding area and leaving it the entire fall is a great way to better understand the location. This buck felt comfortable working this scrape because it is extremely secure and hard to approach undetected. Believe me, I want to!

How does a hunter use this situation to their advantage? The oldest bucks tend to approach a scrape from downwind and may only scent check it from a distance. The right set up is situational, depending on good access and a knowledge of how bucks move in and out of that area. My decision to attempt a morning or evening hunt is usually dictated by which time period will allow me to get in clean. The difference between success and failure is usually measured in a few degrees of wind or yards of distance. You learn by screwing up a few times.

Understanding Thermal Hub Scrapes

There is one type of scraping behavior that I find fascinating. In hilly terrain some of the largest and most heavily used primary scrapes show up in low areas where valleys or draws join together. These scrapes can see a lot of use peaking in the days leading up to the cruising phase of the rut.

A few years ago I heard these locations described as thermal hubs. The hub is created when falling thermals pool in a central low area early and late in the day. A buck can pass through the thermal hub and scent check a large area for other deer, most importantly does nearing estrus. Often they bed in or near the hub. This is classic pre-rut seeking behavior in hill country. I first learned about this behavior in the collegiate level deer hunting academy that is Dan Infalt’s Hunting Beast forum and have not heard it discussed anywhere else.

In this random location from Google Earth the red circles indicate where low thermal hubs would occur with yellow arrows representing falling thermals in the evening and night.

Thermal hub locations often contain massive perennial scrapes and signpost rubs. The more doe bedding on the surrounding ridges the better. Low thermal hubs are challenging to hunt due to the swirling air currents and the likely proximity to bedded bucks. More often I use thermal hub scrapes for trail camera inventory sites and target the nearby bedding of rutting bucks using the thermal hub scrape as a likely direction of travel.

Five different nice bucks hit this public land thermal hub scrape in a 5-day period. Similar activity happens every year in this location.

I have noticed similar activity, including perennial primary scrapes, on the spine of ridge systems where multiple secondary ridges join together. Rising thermals converge on these locations from multiple directions. This location could be called a high thermal hub.

These high hubs see strong rising air currents on calm, sunny, high pressure days that can draw the scent stream of a tree stand hunter right up through the tree tops. In other words, a high thermal hub in the right spot can be a lethal cruising setup during the rut.

Scrape Bedding

Another unique behavior that I have observed is scrape bedding. Some primary scrapes have bucks bed in them repeatedly through the fall. Scrape bedding seems to occur most often in the evening or at night and in areas with decent age structure and buck to doe ratios in the herd. In other words, where the rut is most competitive. I have noticed after a younger buck beds in a scrape a more mature buck usually shows up shortly thereafter and tears up the scrape.

This series of pictures was taken over two consecutive years at the same perennial scrape located in a public land thermal hub. You can see the same symmetrical 8 pointer bedded in the scrape both years.

Any scrape that sees this bedding behavior tends to be in security cover. Many, but not all, of the scrape bedding occurs in thermal hubs. Beyond that I have a lot questions still to answer about bucks bedding in scrapes.

Breeding Stations

A different interesting scrape behavior is that of does using scrapes as breeding stations. Does that are near estrus sometimes wait near scrapes for a buck to show up. It seems this is most common in areas of low deer densities but I have seen it in other areas as well.

Although does frequently use licking branches at other times of the year it seems like they avoid scrapes near peak rut unless they are nearing estrus. In this example a doe visits a scrape under my trail camera (left) on the morning of November 7^th and it’s not a coincidence that two big bucks are on camera later that morning.

As you can see, scrapes can have many meanings and many uses. Hopefully this gives you some ideas about scrapes in the areas you hunt. As always, good luck!
