Insects That Can Make Screeching Noises: The Sounds of Southeast Alabama

While we often associate insect noises with buzzing or chirping, several species in Southeast Alabama are known for their distinct screeching sounds. These noises can be startling and sometimes even concerning, especially when they originate from inside your home. Let’s explore some of these noisy insects and what their screeches might signify.

1. Cicadas: The Summer Serenaders (and Screechers)

Cicadas are perhaps the most well-known screeching insects. These large, winged insects produce loud, high-pitched sounds by vibrating specialized membranes on their abdomens.

• Sound: A loud, buzzing, or screeching sound that can be heard from a considerable distance.
• Reason: Male cicadas produce these sounds to attract mates.
• When: Primarily during the summer months.
• Location: Found in trees and shrubs.

2. Crickets: The Nighttime Chirpers (and Sometimes Screechers)

While crickets are more commonly known for their chirping, some species can produce a louder, more abrasive sound that borders on a screech.

• Sound: A sharp, rapid, high-pitched sound that can be startling.
• Reason: Male crickets create these sounds to attract females and establish territory.
• When: Primarily at night.
• Location: Found in grassy areas, under rocks, and sometimes inside homes.

3. Cockroaches: The Hidden Hissers (and Screechers)

Certain cockroach species, particularly the Madagascar hissing cockroach (which is less common in typical homes, but is worth including), and when other cockroaches are disturbed, can produce a hissing or screeching sound.

• Sound: A sharp hissing or screeching sound, often accompanied by rustling.
• Reason: Used as a defense mechanism or to communicate alarm.
• When: When disturbed or threatened.
• Location: Found in dark, moist areas, such as kitchens, bathrooms, and basements.

4. Longhorned Beetles: The Wood-Boring Screechers

Longhorned beetles, also known as wood borers, can produce a screeching sound when disturbed or when their larvae are feeding inside wood.

• Sound: A sharp, grating, or screeching sound.
• Reason: Larvae feeding inside wood, or adults rubbing body parts together when disturbed.
• When: Throughout the year, especially during the larval stage.
• Location: Found in or near wood, including trees, lumber, and wooden structures.

5. Katydids: The Nocturnal Noise Makers

Katydids, related to crickets and grasshoppers, produce a variety of sounds, including some that can be described as screeching.

• Sound: A sharp, clicking, or screeching sound, often heard at night.
• Reason: Used for mating and communication.
• When: Primarily at night during the summer and fall.
• Location: Found in trees and shrubs.

What to Do If You Hear Screeching Insects:

• Identify the Source: Try to pinpoint the location of the sound to determine the type of insect.
• Inspect for Damage: If you suspect wood-boring insects, inspect wooden structures for signs of damage.
• Contact Pest-Ex: If you’re concerned about an insect infestation, contact Pest-Ex for a professional inspection and treatment plan.

By understanding the insects that produce screeching noises, you can better identify potential problems and take appropriate action to protect your home.
