About 25% of Miami Residents Reporting Seing A Roach In The Last 12 months.

Florida has the largest fauna of roaches in the U.S. There are at least 69 different cockroach species found in the United States, over 38 can be found in Florida. 

Seeing more big roaches this year? According to the U. S. Census Bureau American Housing Survey (AHS) 2021 Servey of the Top 15 Metropolitan Areas surveyed for Housing Quality Miami was the #3 again in roach sightings by residents with 24.97% reporting seeing evidence of roaches in the last 12 months.

In 2021 Total homes surveyed 2,175.2 of which 543.1 or 24.97% reported seeing evidence of roaches. 293.9 or 54.12% of  homeowners and 249.2 or 45.88% of renters. 

In 2019 Total homes surveyed 2052.1 of which 534.2 or 26.03% reported seeing evidence of roaches. 251.8 or 47.14% of homeowners and 249.2 or 46.65% of renters. 

Pest infestations in housing units are a significant issue in Miami, with low-income households and those with structural problems or water leaks being more susceptible. 

A big roach during periods of drought, cockroaches are more likely to invade structures in search of moisture and food. This can lead to an increase in the number of cockroaches found indoors, especially the larger species such as American and Oriental cockroaches.

Pests, such as cockroaches and rodents, pose public health risks and can lead to various diseases and allergies. According to the 2019 American Housing Survey (AHS), approximately 14 million housing units reported roach sightings, while nearly 14.8 million reported rodent sightings.

The AHS data also highlights disparities between homeowners and renters, as well as geographical differences. Cockroach sightings are more frequent in renter-occupied units and units in the South.

To address the issue of pests in housing units, it is essential to implement effective pest control measures, improve housing quality, and address contributing factors such as water leaks, structural problems, and neighborhood conditions.

There are at least 69 different cockroach species found in the United States, 38 can be found in Florida. Florida has the largest fauna of roaches in the U.S.

This paper summarizes the synonymy, distribution, and ecological data of 38 cockroach species in Florida which belong to 24 genera in 4 families. The authors provide valuable information on other species that are known to occur in nearby areas and could potentially be found in Florida.

Thirteen of the species, which include many of the important pests, have been introduced to Florida from Africa (7), the Neotropics (3), and Asia (3). These exotic species seem to be heavily dependent on human disturbance, and only two, Pycnoscelis surinamensis (L.) and Periplaneta australasiae (F.), are commonly found in natural communities away from human influence. Blattella germanica (L.) and Supella longipalpa (F.), both introduced, are strictly domiciliary.

The majority of the native species (15) have neotropical distributions and are not found north of Florida. Four species, Chorisoneura texensis Saussure & Zehntner, Euthlastoblatta gemma (Hebard), Eurycotis floridana (Walker), and Ischnoptera deropeltiformis (Brunner), are restricted to the southeastern U.S. and are the northernmost representatives of neotropical genera.

Five species of Parcoblatta, which are widely distributed in the Southeast, reach their southern limits in Florida. Finally, the paper notes that there is one endemic species, Arenivaga floridensis Caudell, which is restricted to sandy areas in central Florida.

Overall, this paper provides valuable insight into the diversity of cockroach species in Florida and their distributions, including several species that are of ecological or economic importance.

AN IPM APPROACH FOR OUTDOOR COCKROACHES

An 80% or better reduction in cockroach abundance can be achieved using the following IPM approach.

Use only a thin layer of mulch around the home that extends 1 ft (30.5 cm) out from the foundation. This will allow drying time and make conditions less conducive to cockroach survival.

Apply control products within 3 feet (91.5 cm) of the home in pine straw, fallen leaves, or ivy, and next to other cockroach habitats such as garden borders, large rocks, or railroad ties. Always follow the label.

Treat sheltered cracks and crevices such as porch corners, under ledges, in crawl space gratings, and under garage doors. Baits or liquid products can be used, but not both at the same time in the same place.
