Caddisfly

Adult caddisflies resemble moths, with tent-like wings held over their abdomen when at rest. They are typically small, ranging from 1/2 to 1 inch long, and have long, thread-like antennae. Their coloration is usually drab, in shades of brown or gray, providing camouflage near water sources.

Caddisflies are attracted to lights, so you might find them near windows or doorways at night. The presence of numerous caddisflies indoors, especially near standing water or aquatic habitats, could indicate a nearby breeding source. Larval cases, made of small pebbles or plant debris, may also be found in or near water sources.

MBPC focuses on source reduction to control caddisfly populations. Eliminating standing water and reducing outdoor lighting near homes can help. While insecticides are rarely needed, our SC Department of Pesticide Regulation-licensed technicians can advise on targeted treatments if necessary.

Reduce outdoor lighting to minimize attraction. Ensure proper drainage around your Myrtle Beach home to eliminate standing water sources. Keep windows and doors properly screened to prevent caddisflies from entering your home. Contact MBPC for a consultation on managing aquatic insect populations near your property.

Caddisflies are aquatic insects, with larvae found in streams, rivers, ponds, and lakes along the Grand Strand. The adults are commonly found near these water sources, as well as in nearby vegetation. In Myrtle Beach, they thrive in the numerous tidal creeks and salt marshes.
