They don&#8217;t seem to be doing much damage yet, but another spraying couldn&#8217;t hurt. So I&#8217;m making a new essential oil bug spray &#8211; slightly stronger this time, bigger batch. I&#8217;ve increased the amount of dish soap and the tea tree and rosemary, supposedly these are most effective against aphids. Lavender, lemon and ethanol kept at the same concentration.<br><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>280 drops of essential oil (~1.4%):\n<ul class=\"wp-block-list\">\n<li>100 drops tea tree<\/li>\n\n\n\n<li>81 drops rosemary<\/li>\n\n\n\n<li>75 drops lavender <\/li>\n\n\n\n<li>15 drops lemon <\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>30 mL 95% bio-ethanol (~3%)<\/li>\n\n\n\n<li>25 drops of mild dish soap<\/li>\n\n\n\n<li>distilled water to 1000 mL<\/li>\n<\/ul>\n\n\n\n<p>Ended up being way more than I need.

Tomorrow I&#8217;ll clean the most affected plants off under the shower and perhaps do another spray on them, hopefully that should be enough to keep them away for a while. I did have some irritation in one eye after spraying, so I&#8217;ll be more careful with that.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>No big thrips infestation yet this year.
