Coqui Frog observations !

[allensylves]

The latest county e-mail report had a discussion of coqui frog control. They mention that caffeine and pyrethroids were used in testing and found to control coquis. However, the cost, effectiveness and federal requirements proved to be hurdles. Most likely this was mainly the federal requirements, which are a major hassle for a minor use.
The Illinois Dept. of Public Health has some information on use of pyrethroids for mosquito control (edited):

PYRETHROID INSECTICIDES
What are pyrethroid insecticides and how are they used?
Pyrethroids are a group of man-made pesticides similar to the natural pesticide pyrethrum, which is produced by chrysanthemum flowers. These include permethrin (Biomist®, resmethrin (Scourge® and sumithrin (Anvil®. Pyrethroids are found in many commercial products used to control insects, including household insecticides, pet sprays and shampoos. Some pyrethroids also are used as lice treatments applied directly to the head and as mosquito repellents that can be applied to clothes.
What happens to pyrethroids after they are sprayed?
After spraying, pyrethroids settle onto the ground and flat surfaces. Because pyrethroids are mixed with water or oil before being applied, the amount of insecticide left on surfaces is very small. Pyrethroids are broken down by sunlight and other chemicals in the atmosphere. Often, they last only one or two days in the environment.
Pyrethroids usually do not get into groundwater and do not contaminate drinking water supplies. Pyrethroids are eventually broken down in the soil.

So if you buy some Resmethrin, etc. (labeled for mosquito control) in order to control mosquitoes around your home at night, you might achieve other benefits.
