Altosid Pro-G Mosquito Larvicide
Altosid Pro-G is an extended-release granular insect growth regulator formulated to prevent mosquito larvae from emerging as adults, providing weeks to months of residual control that makes it especially cost-effective for large or recurring breeding sites. Compared with quick-acting biological larvicides like BTI dunks and bits, Altosid trades faster knockdown for longer persistence and reduced reapplication frequency, making it a strong technical and financial choice for municipal and commercial programs focused on suppression over time.

Review Summary
"Users report Altosid Pro-G provides reliable, long-lasting control by preventing mosquito emergence and is favored for larger standing-water sites; some note it doesn’t kill larvae immediately and can be pricier than granular options. Overall it’s praised for duration and ease of use in routine mosquito programs."

BTI Mosquito Dunks
Mosquito Dunks deliver Bacillus thuringiensis israelensis (Bti) in a slow-release tablet that rapidly kills mosquito larvae in standing water while remaining safe for people, pets, and most wildlife. They are inexpensive and extremely user-friendly for spot and irregular water sources, producing faster larval mortality than IGR-only products but typically offering shorter residual protection than extended-release IGRs like Altosid Pro-G.

Review Summary
"BTI Mosquito Dunks are widely loved for being safe, easy to use, and highly effective at killing mosquito larvae in small containers and ponds; reviewers only caution that heavily organic or flowing water can reduce effectiveness and repeat applications may be needed. Many users rely on them for backyard and community mosquito control."

Nyguard IGR Concentrate
NyGuard IGR Concentrate is a professional-strength liquid insect growth regulator designed for dilution and targeted application to breeding habitats, giving applicators flexible dosing and favorable per-treatment economics at scale. Unlike biologicals that deliver immediate larval mortality, this concentrate disrupts development to reduce future adult populations and—when applied precisely or tank-mixed—can extend control longevity compared with single-mode treatments, though it requires calibrated application to maximize cost-effectiveness.

Review Summary
"NyGuard IGR Concentrate is viewed positively by professionals for its potency at low rates and residual prevention of adult emergence, but homeowners note it requires proper dilution/equipment and careful handling, and can be more expensive than simpler products. When applied correctly reviewers report good suppression though results depend on application quality."

Gentrol Point Source IGR
Gentrol Point Source uses a controlled-release point-source format to dispense a juvenile hormone analog continuously at infestation hotspots, offering long-duration suppression with minimal worker interaction or frequent reapplications. Its technical advantage lies in sustained, localized disruption of pest development—making it especially valuable in confined or indoor sites—while higher per-unit costs are often offset by reduced labor and the ability to pair with quick-acting larvicides for integrated programs.

Review Summary
"Gentrol Point Source IGR is appreciated by pest pros for providing ongoing suppression of target insects (especially stored-product pests and flies) with discreet placement, though some consumers find the devices costly and location-dependent for best results. Reviews indicate solid supplemental control when used as part of an IPM program."

Summit Mosquito Bits
Summit Mosquito Bits are a Bti-based granular formulation designed for rapid larval control in small containers and shallow water, providing an affordable, fast-acting spot-treatment option for residential or transient breeding sites. They complement longer-lasting IGR products (such as Altosid or NyGuard) in integrated approaches by delivering immediate reductions in larval numbers while IGRs suppress subsequent generations, though their shorter persistence means more frequent re-treatment in high-pressure areas.
