It’s hard to expose forcefulness out ants to lethal temperatures because they motion inside the mound to avoid temperature extremes. When temperatures drop, forcefulness out ants motion deeper into the warmer soil below the surface to avoid the cold. However, if the temperatures drib rapidly they may non live able to avoid the cold, particularly if moisture soil prevents them from moving deeper inward the mound. Persistent mutual depression temperature temperatures are required to impact forcefulness out emmet populations.
Fire ants buy the farm speedily when exposed to temperatures inward the teens or lower. Cold impacts on forcefulness out emmet populations are localized. Fire emmet mounds located nigh homes together with other estrus sinks volition live protected from the colder temperatures to roughly extent. Even if roughly colonies die, others volition survive. Over time, nether optimal conditions, population densities volition rebound to pre-existing levels or larger.
A drib inward visible activity does non e'er hateful a decreased population. On warmer days afterwards the recent mutual depression temperature snap, dead forcefulness out ants workers were establish on the overstep of mound indicating roughly ants had survived to motion the dead ants out of the colony. When the atmospheric condition warms i time to a greater extent than inward the spring, it volition live of import to go along to sentry for mounds. Problems arise when the perceived drib inward population causes population administration to cease.
