They would almost certainly escape into the wild and breed with native or natural species, creating problems like how asian beetles are replacing ladybugs, and earwigs spread like an invasive species, not to mention African honeybees displacing other species of bees.

I'm just over here trying to figure out how bugs are more environmentally acceptable than other life forms. Nothing gets around the law of conservation of energy. Trillions of bugs don't just grow spontaneously. They still need to eat a shit ton of feed. Of course we all know this has nothing to do with the environment, and everything to do with control.
Just because I was curious, I tried to figure out how many crickets a person would need to eat to replace meat. Of course, all of the dishonest assholes pushing this try to avoid providing inconvenient facts, so I've had to dig around and use some estimates.
According to most sources, they use 3.5 oz of cricket powder for comparison against regular meat. That serving is said to provide around 13g of protein, for around 3.7g per ounce. The USRDA for protein (which is bullshit, but we'll stick with government numbers for government bullshit) varies by weight and sex, but an average of 50g. 70 for pregnant women.
The number you won't find is how many crickets it takes to make that 3.5 oz serving. The best numbers I've been able to find are between 1500 and 2500 crickets per pound, depending on species. We'll call it 2000 crickets per pound, or 125 crickets per ounce. To get the government recommended protein per day, you need to eat 13.5oz of crickets, or roughly 1700 crickets.
For purposes of rough numbers, we'll assume that on average everyone needs the same protein. Some need less (small children, elderly) and others need more (pregnant women, growing teenagers) so we'll say those even out. There's are 330M people in the US. To eliminate meat as the greenies want, the US would need to consume 561 BILLION crickets per day. More than 200 TRILLION crickets per year.
Who cares about how many crickets they would feed you? Numbers wise flies or beetle grubs take a lot less input to generate protein than say a cow sheep or pig it also takes far less time to generate it.
that doesn't matter though, it should be used as animal feed not human feed.
Conservation. Of. Energy. Energy input equals energy output. Feeding the world with insects will still require massive crop farming for insect feed at a time when countries are signing onto the WEF fertilizer reduction plan. Lower crop yields equals fewer bugs.
Dipshit greenies think that eating bugs means eating from a Chinese street vendor, with two deep fried grasshoppers on a stick. In reality, it means eating thousands of insects. Every day. And shipping feed and processed bugs around the world. It changes nothing.
It takes way less resources to produce the same amount of cricket protein as beef protein.
Meat production is extremely wasteful.
If you are trying to figure it out I suggest you do some badic research in that.
