What immediate consequence results from crushing a mother wolf spider carrying young?

Answer

Immediate release of eggs or a swarm of newly hatched spiderlings.

A critical practical reason to avoid crushing a wolf spider involves the maternal care exhibited by females. Wolf spiders carry their egg sacs attached to their spinnerets located at the rear of the abdomen. After hatching, the mother spider often carries the numerous young spiders on her back until they are sufficiently developed to be independent. If a panic-induced smash results in the destruction of a pregnant or mother-carrying female, the immediate result is the sudden dispersion of the entire brood—either the unhatched eggs or dozens of mobile spiderlings—directly into the surrounding living space, thereby instantly multiplying the perceived spider problem.
