Remove ectoparasites from nests to increase survival or reproductive success
A replicated, paired site study over two summers in 1991-92 in central Scotland (Alves 1997) found that sand martin Riparia riparia chicks from nests treated with Alugan pesticide (4.25% Bromocyclen) had fewer ectoparasites than chicks from untreated nests and fledged at higher weights (average of 18.8 g for 44 treated nests vs. 18.0 g for 44 control nests; within pairs, chicks from treated nests were heavier in 61% of cases). However, there was no difference in nestling survival between treated and control nests.
