I am in Santa Fe, TX, near the coast, but in more of a rural area. We have lots and lots of Crawdads that burrow holes in our yard and ditches. Does anyone know how to get rid of them or getting them to leave? It makes the yard really hard to walk in because of the holes.
I can appreciate your desire to do something about this, Pamela, but I'm afraid the only longterm solution is to work to improve the drainage on your property. Most sources specifically recommend against chemical controls because of the threat to water quality and how widely they can be distributed by water movement. No chemical controls are registered in Texas. For some additional perspective and guidance, see this from Virginia Cooperative Extension: http://pubs.ext.vt.edu/420/420-253/420-253.html From Texas A&M: http://landscapeipm.tamu.edu/what-is-ipm/ipm-concepts/pest-identification/good-bug-bad-bug/neither/crawfish/
