  <dc:description>&lt;h3 id="ps7163-sec-0001-title" class="article-section__sub-title section1"&gt;BACKGROUND&lt;/h3&gt;&lt;p&gt;Pest management professionals will require a diverse, adaptive abatement toolbox to combat advanced challenges from disease vector and nuisance insect populations. Designed for post-application longevity, insecticidal paints offer extended residual effects on targeted insect pest populations; a measured understanding of active ingredient bioavailability over time is valuable to fully assess treatment efficacy and potential environmental risks. This study was initiated because&amp;nbsp;a nuisance net-spinning caddisfly,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Smicridea fasciatella&lt;/i&gt;, is lowering the quality of life for riverfront residents at the type locality.&lt;/p&gt;&lt;h3 id="ps7163-sec-0002-title" class="article-section__sub-title section1"&gt;RESULTS&lt;/h3&gt;&lt;p&gt;We tested the efficacy and potential mobility of a transfluthrin-based paint (a.i. 0.50%), comparing the impacts of UV exposure and substrate texture over time. Direct UV exposure decreased efficacy (β ± S.E.&amp;nbsp;= 0.008 ± 0.001,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;P&lt;/i&gt; &amp;lt; 0.001) and a coarse texture maintained greater efficacy (β ± S.E.&amp;nbsp;=&amp;nbsp;−3.7 ± 1.3,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;P&lt;/i&gt;&amp;nbsp;=&amp;nbsp;0.004) over time. Notably, the coarse texture + indirect UV treatment maintained 100% mortality after 240 days. UV exposure and substrate texture did not have a significant impact on leachate concentrations over time, and successive immersion tests indicated a two-phase emission pattern. Bioaccumulation increased with time on the cuticle of dead adult&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;S. fasciatella&lt;/i&gt;; after 24 h of direct exposure the concentration of transfluthrin&amp;nbsp;was 25.3 ± 0.9&amp;nbsp;ng/caddisfly with a maximum concentration of 345 ng/caddisfly after 7 days.&lt;/p&gt;&lt;h3 id="ps7163-sec-0003-title" class="article-section__sub-title section1"&gt;CONCLUSION&lt;/h3&gt;&lt;p&gt;Our predictions were validated with measured, time-dependent impacts on efficacy, leachability, and bioaccumulation. Because of the mobility of active ingredient&amp;nbsp;in the environment, insecticidal paints merit low-impact protocols to improve public health outcomes and environmental safety. © 2022 Society of Chemical Industry.&lt;/p&gt;</dc:description>
