267, it took me more than two months to establish such a healthy colony on a property that has had maybe more than 100,000 mature BSF grubs released on it over a two year period. It takes a little patience, but in Texas it should just be a matter of time before you succeed. The fact that you did see a lot of BSF eggs in your BioPod indicates you have a breeding population on your property.
I doubt that hot weather will kill the eggs but a lack of humidity will. Having said that, I also doubt that there is a lack of humidity in your unit because of the melon and other food scraps.
How closely have you studied the waste for signs of smaller BSF grubs? You might want to try turning over a few pieces of food scraps to see if smaller BSF might be present.
Hot weather will definitely be an issue when your colony starts to become dense with grubs. A dense colony with a lot of available food generates significant heat. On especially hot or windless days I add a few wood spacers between the BioPod lid and body. I think it significantly increases ventilation. You can also simply remove the lid but I wouldn't recommend doing that overnight. I do often leave the spacers in place overnight and I haven't had an problems from raccoons yet. If you remove the lid be careful where you set it because ants will raid the eggs in the egg disc.
