Can I use this in mulch and will it be safe for my dog and cat?
Answer by ChewyAug 07, 2021
To kill fungus gnat larvae in the soil, water your plants with a "tea" made from Mosquito Bits. This product is harmless to pets.

Can I use these in a pond stocked with koi and plants?

Can this be put in dog water nowls?
Answer by ChewySep 05, 2022
While Mosquito Bits kill mosquito and fungus gnat larvae in their respective habitats, they are labeled for use in animal watering troughs, ponds, birdbaths, and other areas in which animals and pets will drink and bathe. This is also completely harmless to plants, fish, frogs, turtles and beneficial insects. They can be applied to water and soil used with edible plants, fruits and vegetables.

Can I put this in my pool with my kids swimming in it?
Answer by ChewyMar 21, 2022
We do not recommend placing this in a pool while anyone is swimming. Avoid breathing dust. This causes moderate eye irritation. Avoid contact with eyes or clothing. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, using tobacco, or using the toilet. Do not apply directly to treated, finished drinking water reservoirs or drinking water receptacles when the water is intended for human consumption.

Works great for a couple weeks

Liked the fast action these provided but results only last a couple weeks. No problem in my sized 500 gal pond with this large bag of product.

Mosquito Bits

I "assume" they work. I put some in my birdbath and so far, no larvae. The writing is so small that I'm not sure of how to use the item, the amount needed, or when do I repeat the application. As for the delivery service.... the person delivering the item left the cardboard box containing the Mosquito Bits, out in the rain. Luckily, the Mos.Bits are inside a plastic type bag.
