Microbe-Lift BMC 6 oz | 8% Bti Liquid, Treats 2,000 Gallons

Biological Mosquito Control and the Reason It Only Hits Larvae

This is a bacterial product, not a synthetic one. The active ingredient is Bacillus thuringiensis subspecies israelensis, declared on the label as solids, spores and insecticidal toxins, at eight percent by weight. A larva feeding in the water column takes the material in, and the toxin then acts in its gut. Adult insects on the wing are untouched by it, which is the trade-off that comes with a larval product. Treating the water is therefore preventive work rather than a response to a swarm already flying. The label rate is 2.5 ml per thousand gallons of standing water every other week, doubling where two thousand gallons are being held. Weekly application is permitted where the pressure justifies it. Ecological Laboratories also give a surface figure of one teaspoon per five hundred and forty square feet of total water column. Each application stays active for up to fourteen days, with site conditions deciding the exact figure. The registration number is 62637-1-74466 and the product is made under establishment number 74466-FL-001. It disperses into the water instead of floating, and it leaves no organic or inorganic residue. It may be applied where aquatic life, fish and plants are present. Bacterial larvicides also carry a much lower resistance risk in target populations than chemical alternatives such as methoprene.

Sizing This Larvicide Against the Water You Actually Hold

Start with the volume rather than the bottle. This size holds about 177 ml and treats two thousand gallons across roughly sixteen months. Two thousand gallons takes 5 ml a fortnight, which is twenty-six doses and 130 ml in a full year. The bottle therefore covers sixteen months of continuous fortnightly treatment. Anyone running a smaller feature will get proportionally longer from it. The labelled sites run well past ponds. Water gardens, birdbaths, fountains and statuary open the list. Rain barrels, roof gutters, drains and buckets sit on it too. Plant trays, planters, pool covers, old tires, abandoned swimming pools and stock tanks finish it. Plant trays and planters appearing there is useful to know, since irrigation runoff standing in a saucer breeds as readily as a rain barrel does. Mosquito larvae are the only pest this registration covers, and drinking water sources are excluded. The signal word is CAUTION, and the label warns the material is harmful if inhaled or absorbed through skin. Avoid contact with skin, eyes and clothing when measuring. Keep it cool and dry between applications and do not reuse an empty container.
