“Chafer” has three common meanings depending on context: a type of beetle that damages lawns, a serving dish used in catering, or shorthand for skin chafing caused by friction. If you searched this term, you likely encountered one of these and want to know what it refers to. Here’s a clear breakdown of each.
Chafer Beetles
Chafer beetles are a group of scarab beetles whose larvae (called grubs) feed on grass roots and can destroy lawns, golf courses, and turf fields. The most well-known species in North America is the European chafer, a tannish to reddish-brown beetle about half an inch long. It looks similar to a May or June beetle but is slightly smaller and lighter in color.
Adult European chafers emerge from the soil in early summer, typically at dusk on warm, clear nights. They swarm around small trees and shrubs to mate, then return to the ground to lay eggs. The real damage comes from their larvae: white, C-shaped grubs with reddish-yellow heads and visible legs, ranging from a quarter inch to almost one inch long. These grubs feed on grass roots from late summer through fall and again in spring, creating brown patches of turf that peel up easily because the root system has been eaten away.
Animals make the problem worse. Skunks, raccoons, and crows dig up lawns to feed on the grubs, tearing apart turf in the process. According to Cornell University’s integrated pest management program, the treatment threshold for European chafer grubs is just 5 to 8 per square foot, lower than most other grub species. That said, Cornell’s research in upstate New York found that insecticide treatment is actually needed only about 20% of the time on home lawns and golf course fairways.
Managing Chafer Grubs
Before treating, it helps to cut a square foot of turf and count the grubs underneath. If you’re consistently finding 5 or more European chafer grubs per square foot across several areas, intervention may be warranted. One biological option is applying beneficial nematodes, microscopic organisms that infect and kill grubs in the soil. The species Heterorhabditis bacteriophora is commonly used for this purpose, though these nematodes don’t establish permanently in the soil and need to be reapplied.
Chafing Dishes (Chafers)
In catering and food service, a “chafer” is a chafing dish: a metal setup designed to keep cooked food warm on a buffet line. The basic components are a frame, a water pan, a food pan, and a lid. A low, steady heat source (typically a small fuel canister) sits beneath the water pan. The water heats up and produces steam, which gently warms the food pan above it. This indirect heat keeps food at serving temperature without scorching or drying it out.
Food safety is the main concern when using a chafer. The USDA recommends keeping hot food at or above 140°F to prevent bacterial growth. Food that drops below this temperature enters the “danger zone” (between 40°F and 140°F), where bacteria multiply rapidly. As a general rule, never leave food sitting out for more than 2 hours. If the room temperature is above 90°F, that window shrinks to 1 hour.
Skin Chafing
Skin chafing is irritation caused by repeated friction, either skin rubbing against skin or skin rubbing against fabric. It happens most often in areas that are warm, moist, and prone to contact: inner thighs, groin, buttocks, armpits, and chest. People of all ages and body sizes experience it, and it’s especially common during exercise, in hot weather, or when wearing rough or poorly fitting clothing.
Friction disrupts the outermost layer of skin, causing redness, stinging, and sometimes raw or broken patches. Superficial chafing typically heals within two to three days. If the friction was severe enough to cause a partial-thickness burn (where deeper layers of skin are affected), recovery can take two to three weeks with proper care.
When Chafing Becomes Something Else
Simple chafing is a mechanical injury that improves once the friction stops. But warm, moist skin folds are also a breeding ground for infection. Intertrigo is a condition where irritated skin in these folds becomes colonized by yeast or bacteria. The key differences: simple chafing tends to look the same on both sides of a fold and improves with rest, while infections are often one-sided or uneven. If you notice pustules, crusting, weeping, or small satellite bumps spreading outward from the irritated area, a secondary infection is likely involved.
Prevention
The goal is reducing friction and moisture. Moisture-wicking fabrics pull sweat away from skin more effectively than cotton. Anti-chafe balms and skin protectants create a barrier layer that lets skin slide rather than catch. Many of these products use ingredients like allantoin (a skin protectant) or petroleum-based barriers to reduce direct contact. Keeping skin folds dry, wearing well-fitted clothing, and applying a protective balm before exercise are the most reliable ways to prevent chafing before it starts.
